The Drift-Reduction for Improved Fractional Flow Reserve (FFR) Using Fiberoptic Technology (DRIFT) Study
In Brief
A clinical study evaluating OpSens Medical OptoWire and FFR for Left Anterior Descending Coronary Artery Stenosis. Completed, enrolled 60 participants across 2 sites.
Detailed Summary
The primary objective of this study is to assess the accuracy, efficacy, and durability of the OpSens Medical OptoWire Deux pressure wire in the assessment of angiographically intermediate proximal left anterior descending coronary artery (LAD) stenoses in clinical practice.
Study Details
Timeline
Interventions
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.
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).
