Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study is designed as a prospective, observational in nature, multi-center, single-arm, clinical registry to estimate the ischemic burden of angiographically intermediate proximal LAD stenosis in clinical practice using the OpSens Medical OptoWire Deux FFR system. Subjects with stable angina or unstable angina who are found to have an intermediate proximal LAD stenosis on coronary angiography with anatomy amenable to PCI and underwent physiological lesion assessment with the OptoWire Deux pressure wire and OCT as part of their routine procedures using standard of care techniques will be enrolled. Patients meeting enrollment criteria will be offered the opportunity to enroll in this observational registry post-procedure. All patients enrolled in this study are expected to be evaluated and treated using a standard of care technique. This study will enroll a total of 60 patients at Columbia University Medical Center and St. Francis Hospital.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Male or female subjects, >18 years of age.
  • Patients with stable angina, unstable angina or non-ST segment elevation myocardial infarction (if the LAD lesion is the non-culprit lesion) and in whom an intermediate proximal LAD de novo stenosis (30-80%) with TIMI flow 3 has been identified on angiography. Note: Patients with multi-vessel disease can be enrolled.
  • Patients have had fractional flow reserve (FFR) and optical coherence tomography (OCT) of the LAD with the OpSens FFR system as part of their routine evaluation as standard of care procedure.
  • Provides written, informed consent and HIPAA consent to use the data in a clinical study.

Exclusion Criteria:

(General exclusion criteria)

  • Patients presented with NSTEMI with the LAD involved as the culprit lesion
  • Any ST-elevation myocardial infarction within the past 30 days.
  • Hemodynamic instability requiring vasopressor or mechanical circulatory support.
  • Prior heart transplant.
  • Known left ventricular ejection fraction ≤40%.
  • LAD supplying akinetic or severely hypokinetic territories if already known based on prior imaging.
  • Patient is enrolled in another clinical study that may impact the results of this study.
  • FFR not acquired per instructions for the OpSens Wire.
  • LAD Lesion not assessed with OCT.

(Angiographic exclusion criteria)

  • Thrombolysis in Myocardial Infarction (TIMI) grade 2 or lower at baseline angiography.
  • Target lesion involves left main (stenosis >50%).
  • Previous percutaneous coronary intervention (PCI) with stent in LAD or left main trunk.
  • Presence of chronic total occlusion in any vessel.
  • Presence of a side branch≥2.75 mm with ≥70% stenosis in the LAD.
  • Bifurcation lesion that resulted in the stent implantation of a side branch.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available.

Experimental: Opsens Medical OptoWire
Subjects who will have or recently had FFR using the Opsens Medical OptoWire Deux FFR system.
Device: OpSens Medical OptoWire

The OptoWire is FDA approved to measure pressure in coronary vessels during diagnostic angiography and coronary interventions.

The OptoWire Deux pressure wire (OpSens Medical, Quebec, Canada) is a novel technology utilizing optical coherence technology to enhance FFR assessment of the coronaries.

Other Names:
  • OpSens Medical OptoWire Deux FFR System
Procedure: FFR
A guide wire-based procedure that can accurately measure blood pressure and flow through a specific part of the coronary artery. FFR is done through a standard diagnostic catheter at the time of a coronary angiogram (a.k.a. cardiac catheterization).
Other Names:
  • Fractional Flow Reserve

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percentage of Recordings of Significant Drift in Pre and Post-PCI
Time Frame: During procedure, approximately less than an hour
The rate of significant drift is defined as FFR <0.97 or >1.03 with the in the pre-percutaneous coronary intervention (PCI) FFR recording using the OpSens OptoWire Deux pressure wire system. FFR is calculated by measuring the ratio between pressure distal to a stenosis and pressure proximally to stenosis using specialized pressure-measuring guidewires during maximal hyperemia.
During procedure, approximately less than an hour
