DEFINE-FLOW (Distal Evaluation of Functional Performance With Intravascular Sensors to Assess the Narrowing Effect - Combined Pressure and Doppler FLOW Velocity Measurements)
In Brief
A clinical study evaluating Percutaneous coronary intervention (PCI) and Optimal medical therapy (OMT) for Coronary Artery Disease. Completed, enrolled 455 participants across 12 sites in 6 countries.
Detailed Summary
This study evaluates the prognostic value and therapeutic potential of combined pressure and flow measurements when evaluating a coronary artery stenosis. Lesions with intact coronary flow reserve (CFR) despite a reduced fractional flow reserve (FFR) will receive optimal medical therapy. Only lesions with a simultaneous reduction in both CFR and FFR will be treated with percutaneous coronary intervention (PCI).
