Introduction

Optical coherence tomography intravascular OCT is a catheter-based imaging modality used inside blood vessels—most commonly the coronary arteries—to produce high-resolution, cross-sectional images during catheterization procedures. It is widely used to support intraprocedural decision-making in interventional cardiology, especially when clinicians need more detail than angiography alone can provide.

For hospitals and clinics, Optical coherence tomography intravascular OCT is not just a “better image” tool; it is a workflow, safety, and cost-of-care consideration. It affects contrast utilization, procedure duration, sterile handling processes, data storage, staff competency, and ongoing spend on disposable imaging catheters and service contracts.

This article provides operationally focused, non-advisory guidance for hospital administrators, clinicians, biomedical engineers, procurement teams, and healthcare operations leaders. You will learn what Optical coherence tomography intravascular OCT is, typical clinical use cases, general safety considerations, how basic operation usually works, how outputs are commonly interpreted, how to troubleshoot failures, how to approach infection control and cleaning, and how the global market and supplier ecosystem tends to look across multiple countries.

All information is general and educational. Clinical decisions must be made by qualified professionals using local protocols and the manufacturer’s instructions for use (IFU).

What is Optical coherence tomography intravascular OCT and why do we use it?

Optical coherence tomography intravascular OCT is an intraluminal imaging medical device that uses near-infrared light delivered through a catheter to generate high-resolution images of the vessel lumen and superficial vessel wall. It is often compared with intravascular ultrasound (IVUS): OCT typically provides higher near-surface detail, while IVUS generally offers deeper tissue penetration. The choice between them depends on the question being asked, anatomy, operator preference, and institutional practice.

Clear definition and purpose

In practical terms, Optical coherence tomography intravascular OCT is used to:

Visualize vessel lumen geometry in cross-section and longitudinal views
Characterize lesion morphology at a level of detail not available on angiography alone
Assess pre-intervention anatomy to support device selection (for example, stent sizing)
Evaluate post-intervention results (for example, stent expansion and apposition)
Document findings for quality assurance, teaching, and longitudinal care

Because light does not travel well through blood, intravascular OCT imaging typically requires transient blood clearance using contrast media and/or flush solutions, depending on local protocol and manufacturer guidance. This blood clearance requirement is central to both workflow and safety planning.

Common clinical settings

Optical coherence tomography intravascular OCT is most commonly used in:

Cardiac catheterization laboratories (cath labs)
Interventional cardiology suites performing PCI (percutaneous coronary intervention)
Institutions with complex coronary disease programs (e.g., left main, bifurcation, calcified lesions), where intraprocedural imaging is frequently used
Centers running clinical research, training, or quality-improvement programs that rely on standardized imaging documentation

The technology is typically integrated into a broader cath lab ecosystem that includes fluoroscopy, hemodynamic monitoring, contrast injectors, sterile disposables, and image archiving.

Key benefits in patient care and workflow

From a care-delivery perspective, the main value proposition is precision. Optical coherence tomography intravascular OCT can support more confident, more standardized procedural decisions by clarifying what angiography may under-represent (for example, subtle dissections, stent malapposition, or underexpansion).

From an operational perspective, benefits commonly include:

More structured documentation through stored pullbacks, measurements, and annotations
Improved team communication when image findings can be shown and discussed in real time
Enhanced training capability, because OCT images are relatively intuitive once artifacts are understood
Potential reduction in ambiguity-driven device usage (for example, fewer “trial-and-error” post-dilations), although outcomes depend on practice patterns and should not be assumed

For administrators and procurement teams, it is important to view Optical coherence tomography intravascular OCT as both capital medical equipment (console/software) and a recurring consumables program (disposable imaging catheters, drapes/accessories), with direct implications for case costing, inventory management, and service continuity.

When should I use Optical coherence tomography intravascular OCT (and when should I not)?

Use of Optical coherence tomography intravascular OCT should be driven by a clear clinical question and an operationally safe plan to acquire interpretable images. The technology is most effective when the team understands what the modality can and cannot show, and when blood clearance and catheter handling can be performed reliably.

This section is general information and not medical advice. Appropriate use, contraindications, and procedural details vary by manufacturer, local regulation, and facility protocol.

Appropriate use cases (common scenarios)

Optical coherence tomography intravascular OCT is commonly used when teams want to:

Assess lesion morphology before intervention (e.g., calcification pattern, plaque features, lumen sizing)
Optimize stent selection and placement using measured reference segments
Evaluate stent expansion and apposition immediately after deployment
Identify and characterize edge dissections, tissue protrusion, or residual stenosis after intervention
Investigate mechanisms of stent failure (e.g., restenosis patterns) where imaging is expected to change management
Provide high-quality documentation for complex interventions, teaching, or second-opinion review

In many institutions, OCT is adopted as part of a “precision PCI” pathway, where imaging is used consistently for defined lesion subsets rather than sporadically.

Situations where it may not be suitable

Optical coherence tomography intravascular OCT may be less suitable when:

Adequate blood clearance cannot be achieved safely (image quality will be poor and risk may increase)
The patient’s condition or procedural context makes repeated contrast/flush runs undesirable (local protocols vary)
Target anatomy is large, highly tortuous, or otherwise technically challenging for stable catheter positioning
Heavy thrombus burden or certain lesion characteristics limit interpretability (attenuation and artifact risk)
The incremental procedural time and complexity are not justified by a clear clinical question

It is also important to consider operational suitability: if staff are not trained to recognize artifacts, a high-detail modality can paradoxically increase uncertainty.

Safety cautions and contraindications (general, non-clinical)

General safety considerations for this clinical device typically include:

Contrast/flush burden: OCT imaging frequently requires contrast injections to clear blood; this can affect renal risk management and fluid planning according to local protocol.
Catheter handling risks: Any intravascular catheter carries risk of vessel irritation, spasm, dissection, or trauma if advanced or withdrawn improperly.
Transient ischemia risk: Blood clearance techniques may transiently reduce perfusion; monitoring and procedural discipline are important.
Allergy and sensitivity risks: Contrast media and some materials used in accessories may trigger reactions in sensitive individuals; screening and preparedness are facility responsibilities.
Additional fluoroscopy exposure: OCT itself uses light, not ionizing radiation, but the procedure is performed under fluoroscopy; extra imaging steps can increase overall radiation time.
Device-specific contraindications: These are manufacturer-defined and must be checked in the IFU (varies by manufacturer).

A practical hospital approach is to treat Optical coherence tomography intravascular OCT as a “high-value, high-dependency” workflow: it is safest and most effective when the team has a stable protocol, a clear imaging objective, and a defined stop-rule for non-diagnostic imaging runs.

What do I need before starting?

Successful use of Optical coherence tomography intravascular OCT depends on readiness across people, process, and equipment. This includes cath lab environment readiness, sterile workflow, compatible accessories, and a trained team that can acquire interpretable images safely.

Required setup, environment, and accessories

Typical requirements include:

OCT imaging console/workstation: The capital medical equipment component (cart/console, monitor, processing unit, software).
Pullback mechanism: Often motorized and integrated; exact design varies by manufacturer.
Disposable OCT imaging catheter: Usually sterile, single-use, and packaged with specific handling constraints (varies by manufacturer and local regulation).
Sterile field accessories: Sterile drapes, sterile covers for cables/handpieces if used, and appropriate connector management.
Guidewire and guiding catheter compatibility: Ensure catheter compatibility with common guidewires, guide catheters, and hemostasis valves per IFU.
Flush/contrast delivery: Manual syringe technique or power injector workflow, depending on facility policy and clinician preference.
Imaging integration (optional): DICOM connectivity, procedural reporting integration, and (in some systems) angiographic co-registration (availability varies by manufacturer).
Power and network readiness: Stable power supply, safe cable routing, cybersecurity-compliant network connection if images are stored to PACS or a server.

From a biomedical engineering viewpoint, consider electrical safety checks, preventive maintenance schedules, software patch governance, and accessory compatibility control as part of ongoing hospital equipment management.

Training and competency expectations

Because OCT is high-detail and artifact-sensitive, training should cover both operation and interpretation basics:

Console startup, catheter connection, and sterile handling
Blood clearance technique basics and coordination with the team
Artifact recognition and “non-diagnostic run” criteria
Measurement conventions used by the local clinical team
Data storage, labeling, and documentation requirements
Emergency stop actions and escalation workflow

Competency is not only the physician’s responsibility. Nursing, technologists, and cath lab support staff often perform critical steps (setup, priming, documentation, cleaning). Many institutions formalize competency through checklists, supervised cases, and periodic refreshers.

Pre-use checks and documentation

A practical pre-use checklist usually includes:

Verify system power-on self-test completes without errors
Confirm software login and patient record creation workflow is functioning
Confirm available storage (local and/or network) and correct export destinations
Inspect OCT catheter packaging integrity, expiry date, and sterile indicator
Confirm correct catheter model for intended anatomy and compatibility (IFU)
Verify pullback device readiness and that the catheter is recognized by the console (if applicable)
Prime/flush lines as required and remove air per protocol
Ensure required emergency equipment is present per cath lab standards
Record required identifiers (e.g., lot/serial information) according to facility policy and regulation

For procurement and quality teams, consistent device tracking (including disposable lot capture) supports recall readiness, adverse event investigation, and supply chain transparency.

How do I use it correctly (basic operation)?

Operation of Optical coherence tomography intravascular OCT varies by manufacturer and by local cath lab protocol, but the overall workflow is typically consistent: prepare the system, prepare the sterile disposable catheter, position it safely, perform blood clearance, acquire a pullback, review, document, and dispose/clean appropriately.

This section describes a general workflow and is not a substitute for the IFU or training.

Basic step-by-step workflow (typical)

Prepare the console and workspace
Power on the OCT console, confirm the system is ready, and verify the correct procedure context (patient record, case ID, and storage destination).
Establish sterile workflow and role clarity
Confirm who is responsible for catheter prep, who triggers acquisition, and who coordinates the flush/contrast delivery. A brief “imaging time-out” reduces miscommunication.
Open and prepare the sterile OCT catheter
Maintain sterility, inspect the catheter for visible damage, and confirm the correct model and compatibility. Do not use if packaging is compromised.
Connect the catheter to the system
Connect the catheter to the console interface and pullback device as designed. Ensure connectors are clean and dry to avoid signal dropout (follow IFU).
Prime/purge to remove air
Use the manufacturer-recommended priming steps to remove air from the catheter and associated lines. Air bubbles can create artifacts and may create procedural risk if introduced intravascularly.
Calibration/normalization (if required)
Some systems perform auto-calibration; others require a normalization step. Follow on-screen prompts and IFU (varies by manufacturer).
Advance and position the catheter under fluoroscopy
Over the guidewire, advance to the intended distal imaging position with gentle technique. Avoid forcing the catheter if resistance is encountered.
Plan the pullback and blood clearance
Confirm planned pullback length and imaging segment. Coordinate the flush/contrast delivery timing with acquisition start.
Acquire the OCT pullback
Start acquisition and pullback. Maintain stable catheter position and minimize patient and table movement as much as feasible.
Review image quality and repeat only if justified
If images are non-diagnostic (e.g., blood artifact), decide whether repeating is appropriate based on local safety considerations and clinical need.
Perform measurements and document findings
Capture key frames, measurements, and annotations. Save/export images per institutional policy.
Remove and dispose of the disposable catheter appropriately
Most OCT imaging catheters are single-use disposables; follow local policy and IFU for disposal and sharps management.

Setup, calibration, and operation notes

Operational reliability often depends on small details:

Keep connectors dry and protected from fluid ingress.
Manage cable routing to avoid tension on connectors and reduce trip hazards.
Use only compatible accessories (hemostasis valves, extension tubing) specified by policy and IFU.
Standardize “who presses what” during acquisition to reduce timing errors.

For biomedical engineers, recurring issues often relate to connector wear, pullback motor maintenance, software storage failures, and network configuration. Preventive maintenance and standard work instructions can reduce avoidable downtime.

Typical settings and what they generally mean

Exact options vary by manufacturer, but common configurable elements include:

Pullback length: Defines the imaged vessel segment; longer segments can be useful for diffuse disease but may require more robust blood clearance.
Pullback speed: Balances longitudinal sampling and motion sensitivity; faster pullbacks may reduce ischemic time but can be more sensitive to timing errors.
Frame averaging or image processing presets: Can improve apparent clarity but may affect appearance of fine features; interpretation training is important.
Measurement modes: Lumen diameter/area, reference selection, stent metrics, and reporting templates.
Co-registration features (if available): Align OCT frames with angiographic landmarks to improve communication and documentation (availability varies by manufacturer).

A mature cath lab program often defines default “house settings” for common use cases, with controlled deviation when clinically justified.

How do I keep the patient safe?

Patient safety with Optical coherence tomography intravascular OCT is primarily about disciplined procedural practice: minimizing avoidable risk while ensuring the imaging run is diagnostic enough to justify its use. OCT adds steps to a catheterization procedure, so safety management must consider hemodynamics, contrast/flush planning, catheter handling, and team communication.

This section is general information only. Clinical decisions belong to qualified professionals using facility protocols and manufacturer guidance.

Safety practices and monitoring

Common safety practices include:

Pre-run readiness: Confirm the imaging objective and define what would make the run “diagnostic.” Avoid “just to see” imaging that adds risk without a clear question.
Hemodynamic and ECG monitoring: Maintain standard cath lab monitoring and ensure the team is ready to respond to changes during flush and pullback.
Contrast/flush stewardship: Coordinate contrast delivery method and volume planning per local protocol. OCT often increases contrast utilization, which requires proactive planning rather than reactive dosing.
Catheter handling discipline: Advance and withdraw gently. If resistance occurs, stop and reassess rather than applying force.
Limit repeat runs: Repeating pullbacks due to avoidable artifacts increases contrast burden and procedural time. Standardized technique reduces repeats.
Radiation awareness: While OCT itself is optical, it is performed under fluoroscopy. Reducing unnecessary repositioning and repeat acquisitions can limit overall fluoroscopy time.

Alarm handling and human factors

OCT consoles typically provide on-screen prompts and audible alarms related to connection status, pullback motor function, signal quality, and system faults. Human factors matter:

Assign a clear “console operator” role during acquisition.
Use closed-loop communication when initiating flush and acquisition (“flush starting… acquiring now… pullback complete”).
Treat repeated alarms as a reason to pause and troubleshoot rather than pushing through.

Common high-impact human factors risks include mis-timed flush (leading to blood artifact), cable disconnection mid-pullback, and repeating runs without addressing the underlying cause.

Emphasize following facility protocols and manufacturer guidance

Safety is strengthened by alignment across:

The manufacturer’s IFU (device-specific contraindications and setup steps vary by manufacturer)
Facility policy (contrast management, sterile handling, documentation, and escalation)
Team competency (consistent technique and artifact recognition)

For hospital leaders, a practical safety governance approach includes standardized work instructions, competency tracking, incident reporting pathways, and periodic review of “non-diagnostic OCT runs” to identify process gaps.

How do I interpret the output?

Optical coherence tomography intravascular OCT produces high-resolution images that can be clinically powerful but also easy to misread if artifacts and limitations are not understood. Interpretation typically blends real-time assessment during the case with post-run review for documentation and teaching.

This section describes general interpretation concepts and does not provide clinical advice.

Types of outputs/readings

Common outputs include:

Cross-sectional (axial) images: The primary OCT view—circular slices of the vessel showing lumen, plaque features, and stent struts when present.
Longitudinal reconstructions: A “rail” view that helps visualize lesion length, stent edges, and transitions between segments.
Quantitative measurements: Lumen diameter/area estimates, reference segment selection, stent expansion metrics, and distances relevant to apposition (measurement tools vary by system).
Annotated key frames and reports: Screenshots, labeled frames, and summary reports for the medical record.
Optional integrations: Some systems support co-registration or structured reporting outputs (varies by manufacturer and site integration).

For administrators and informatics teams, outputs also imply data governance: storage capacity, DICOM workflow, naming conventions, and long-term access for audits and case review.

How clinicians typically interpret them (high-level)

Clinicians commonly use OCT to look for:

Lumen size and shape: Helpful for selecting device size and confirming post-intervention result.
Plaque and lesion morphology: Qualitative patterns (e.g., signal-rich vs signal-poor regions) can inform strategy, while recognizing that tissue characterization has limitations.
Calcification appearance and distribution: OCT can show calcific arcs near the lumen clearly; deeper extent may be less visible than with ultrasound-based modalities.
Stent assessment: Strut visualization, apposition, expansion symmetry, edge transitions, and possible dissections are common focal points.
Complications: Identifying flaps, intraluminal material, and irregularities that may require attention per clinical judgment.

Most institutions standardize interpretation language (e.g., what qualifies as “significant” findings) to reduce variability across operators and to support consistent documentation.

Common pitfalls and limitations

Common limitations that can affect interpretation include:

Blood artifact: Incomplete blood clearance can mimic pathology or obscure key findings.
Guidewire shadowing: The guidewire creates a persistent shadow that hides a sector of the vessel.
Limited penetration depth: OCT excels near the lumen but may not visualize deeper vessel structures as well as IVUS, which can matter in certain lesion types.
Motion artifacts: Cardiac motion, catheter movement, or poor timing can blur frames and distort measurements.
Catheter eccentricity: Off-center catheter position can affect apparent measurements and create uneven illumination.
Over-interpretation risk: High-detail images can tempt users to “treat the picture.” Interpretation should be integrated with the full clinical context and facility protocols.

From a training standpoint, one of the most valuable exercises is systematic artifact review—understanding what non-pathologic features look like and when images are non-diagnostic.

What if something goes wrong?

A structured troubleshooting approach can reduce downtime, prevent repeated non-diagnostic runs, and improve safety. When problems occur with Optical coherence tomography intravascular OCT, the key is to separate patient-related concerns (stop and stabilize) from system-related concerns (pause and troubleshoot), and to know when to escalate.

A troubleshooting checklist (practical)

If the system is not producing a usable image or behaves unexpectedly, check:

Patient safety first: Stop acquisition if the patient becomes unstable or if blood clearance is not achievable safely.
Connections: Confirm catheter-to-console connections are fully seated and dry; check for cable strain.
Catheter recognition: Confirm the console identifies the catheter model; incompatible or damaged catheters may not initialize properly.
Air and priming: Re-check priming steps; air bubbles and inadequate purging are common causes of poor image quality.
Blood clearance timing: If images show significant blood artifact, reassess flush timing, delivery method, and coordination (within local protocol).
Pullback function: If the pullback fails to start or stops, check for on-screen prompts, mechanical obstruction, or motor errors.
Software status: Confirm adequate storage space, correct patient/case selection, and that the system is not stuck in an error state requiring restart.
Network/export issues: If saving/export fails, verify network connectivity and permissions; consider local save with later export per policy.
Environmental factors: Electromagnetic interference is less common but cable routing, power instability, and fluid ingress can cause intermittent faults.

When to stop use

Stop using the device and follow facility escalation protocols if:

There is any sign of catheter damage or compromised sterility
The patient’s condition changes and continued imaging would add risk
The system produces repeated errors that cannot be resolved quickly
Imaging quality is persistently non-diagnostic despite appropriate technique
There is concern for equipment malfunction that could impact safety

A “stop rule” is a hallmark of safe adoption. Repeating acquisitions to “make it work” without addressing root cause is a common pathway to wasted contrast, prolonged procedure time, and preventable risk.

When to escalate to biomedical engineering or the manufacturer

Escalate to biomedical engineering when:

The console, pullback device, connectors, or power/network systems appear faulty
The device fails self-test or shows persistent alarms across cases
There are cybersecurity, software update, or integration concerns
Preventive maintenance or calibration status is uncertain

Escalate to the manufacturer (or authorized service provider) when:

The system exhibits repeatable faults that persist after basic troubleshooting
Disposable catheter failures appear clustered (retain lot information per policy)
There is any suspected device defect requiring formal reporting and investigation

Operationally, document the event with as much detail as possible: time, error codes, steps attempted, catheter lot/serial data, and how the issue was resolved.

Infection control and cleaning of Optical coherence tomography intravascular OCT

Infection control for Optical coherence tomography intravascular OCT spans both the sterile disposable components used in the field and the non-sterile capital equipment in the cath lab environment. Because OCT systems include consoles, cables, and touch surfaces, they should be treated as shared hospital equipment with defined cleaning responsibilities between cases.

Always follow facility infection prevention policy and the manufacturer’s IFU. Cleaning agents and contact times vary by manufacturer.

Cleaning principles

Key principles include:

Maintain separation between sterile and non-sterile zones: Use sterile drapes and covers where needed, and avoid bringing non-sterile components into the sterile field.
Assume high-touch contamination: Keyboards, mice, touchscreens, control knobs, and pullback device housings are frequently touched during cases.
Prevent fluid ingress: Do not allow cleaning solutions to drip into vents, seams, connectors, or ports.
Use approved disinfectants: Select products compatible with the surfaces and recommended by facility policy and manufacturer guidance.
Document routine cleaning: Especially for shared medical equipment that moves between rooms.

Disinfection vs. sterilization (general)

Sterilization is intended to eliminate all forms of microbial life and is typically used for invasive instruments that are reused.
Disinfection reduces microbial burden and is commonly used for non-critical external surfaces and non-invasive equipment.

Most intravascular OCT imaging catheters are provided as sterile, single-use disposables and are not intended to be reprocessed (varies by manufacturer and local regulation). The console and pullback hardware generally require cleaning and disinfection rather than sterilization.

High-touch points to prioritize

Common high-touch areas include:

Touchscreen or monitor controls
Keyboard and mouse (or trackball)
Pullback device exterior surfaces and release mechanisms
Cables near the sterile field boundary
Cart handles, drawer pulls, and power buttons
Footswitches (if used) and their cables

In addition, consider less obvious touch points such as cable hooks, clamp points, and accessory bins.

Example cleaning workflow (non-brand-specific)

A typical between-case workflow may look like:

Don appropriate PPE per facility policy.
Remove and discard single-use drapes/covers without contaminating nearby surfaces.
Inspect surfaces for visible soil; follow spill procedures for blood/body fluid contamination.
Wipe high-touch surfaces with an approved disinfectant, working from cleaner areas to dirtier areas.
Respect the disinfectant’s required wet contact time (per product labeling and facility policy).
Avoid spraying directly into vents or connectors; apply solution to the wipe first when appropriate.
Allow surfaces to air-dry fully before reconnecting cables or powering down/up as needed.
Confirm readiness for the next case (cables organized, no residue on optical/electrical connectors).
Record cleaning per local documentation practice (especially in shared-equipment logs).

For operations leaders, the most common gap is ambiguity over “who cleans what.” Clear ownership, training, and auditing reduce variability and improve compliance.

Medical Device Companies & OEMs

In the context of Optical coherence tomography intravascular OCT and similar hospital equipment, it helps to separate manufacturers from OEMs (Original Equipment Manufacturers):

A manufacturer typically brands, markets, and assumes regulatory responsibility for the final clinical device system sold to hospitals.
An OEM may produce components or subsystems (optics modules, motors, imaging sensors, embedded electronics, software libraries, carts) that are integrated into the final product.

How OEM relationships impact quality, support, and service

OEM relationships can influence:

Quality consistency: Component sourcing affects reliability, lifecycle changes, and spare parts continuity.
Serviceability: If proprietary components are involved, service may require authorized channels rather than in-house repair.
Cybersecurity and software updates: Third-party libraries and embedded systems may shape patch cadence and long-term support.
Regulatory documentation: Traceability and change control are essential, especially when component lifecycles change.

Hospitals benefit from asking practical procurement questions: expected service life, parts availability, software support duration, local service coverage, and what “end of support” looks like for installed systems.

Import dependence is common, so distributor strength, training support, and parts availability strongly influence long-term viability.

Iran

Iran has experienced growth in specialized medical services in major urban centers, with variable access across regions. Optical coherence tomography intravascular OCT adoption is shaped by procurement pathways, import constraints, and the availability of consumables. Service and maintenance ecosystems may rely on a limited number of channels, making uptime planning and spare parts strategy important for hospitals.

Turkey

Turkey has a mix of high-capability urban hospitals and expanding private healthcare infrastructure, supporting advanced cath lab technology adoption. Optical coherence tomography intravascular OCT use is often seen in larger interventional cardiology centers, where imaging-guided PCI protocols may be more established. Procurement focuses on service coverage, training support, and predictable pricing for disposable catheters.

Germany

Germany’s market is supported by a mature hospital infrastructure, established cardiology networks, and strong engineering and service standards. Optical coherence tomography intravascular OCT adoption is influenced by clinical guidelines, institutional protocols, and cost-effectiveness assessments within hospital purchasing frameworks. Access is generally strong in urban and regional centers with cath labs, with robust service ecosystems compared to many markets.

Thailand

Thailand has advanced private hospitals and growing public-sector capabilities, particularly in major cities and medical tourism hubs. Optical coherence tomography intravascular OCT adoption often concentrates in high-volume centers performing complex PCI, where training and case mix justify the investment. Import dependence for disposables and the strength of local distributor/service support remain key determinants of sustainable utilization.

Key Takeaways and Practical Checklist for Optical coherence tomography intravascular OCT

Define a clear clinical question before each Optical coherence tomography intravascular OCT run to avoid unnecessary imaging.
Treat OCT as both capital medical equipment and a recurring disposable catheter program in cost planning.
Standardize roles so one person owns console actions and one person coordinates flush/contrast timing.
Confirm catheter model compatibility with guide catheter and guidewire before opening sterile packaging.
Inspect sterile packaging integrity and expiry every time; do not use compromised disposables.
Prime and purge meticulously to remove air; air-related artifacts and risks are preventable.
Keep connectors dry and protected; fluid ingress is a common cause of intermittent failures.
Use a brief imaging time-out to align timing, pullback plan, and stop rules.
Minimize repeat pullbacks by addressing root causes of blood artifact and timing errors.
Recognize that OCT image quality is highly dependent on blood clearance technique and coordination.
Remember OCT uses light, but the procedure still relies on fluoroscopy and adds radiation time if inefficient.
Monitor the patient continuously during flush and pullback, following facility cath lab standards.
Stop imaging promptly if the patient becomes unstable or if adequate blood clearance is not achievable safely.
Avoid forcing the catheter; resistance should trigger reassessment, not increased pushing force.
Use facility-approved contrast stewardship practices and document contrast/flush use per protocol.
Train staff to recognize common artifacts (blood, guidewire shadow, motion) to prevent misinterpretation.
Do not over-interpret high-detail images; correlate findings with the full procedural context.
Use consistent measurement conventions and reporting templates to reduce operator variability.
Ensure images and reports are saved to the correct patient record and exported per policy.
Confirm DICOM/network storage workflows during commissioning, not during live cases.
Capture disposable lot/serial information consistently to support recalls and investigations.
Build downtime procedures so cases can proceed safely if the OCT system is unavailable.
Escalate recurring alarms and error codes to biomedical engineering with detailed documentation.
Keep preventive maintenance and software support schedules visible to cath lab leadership.
Validate cybersecurity and patch governance pathways for network-connected imaging consoles.
Clean and disinfect high-touch console surfaces between cases using approved agents and contact times.
Use sterile barriers appropriately and maintain separation between sterile field and console surfaces.
Do not reprocess single-use OCT catheters unless explicitly permitted by manufacturer and regulation.
Audit “non-diagnostic OCT runs” to identify training gaps and workflow weaknesses.
Verify service response times, parts availability, and loaner policies in procurement contracts.
Align purchasing decisions with local service capability, not only upfront price.
Plan inventory levels for disposable catheters to avoid case cancellations due to stockouts.
Document troubleshooting steps taken during failures to speed manufacturer resolution.
Incorporate OCT workflow into cath lab safety checklists to reduce human-factor errors.
Use structured training for new staff and refreshers for low-frequency users.
Treat image archiving and retention as a governance issue, not a “nice to have.”
Set clear criteria for when OCT is indicated in your institution to support utilization control.
Review manufacturer IFU updates routinely; contraindications and handling steps can change.
