Understanding Virtual Fractional Flow Reserve

Virtual fractional flow reserve (VFFR) is an innovative imaging-based approach that evaluates blood flow through coronary arteries without the need for invasive procedures. It utilizes two angiographic images to create a 3D reconstruction of the artery, where computational fluid dynamics simulations calculate pressure changes. Unlike traditional fractional flow reserve (FFR), VFFR avoids the insertion of pressure-sensitive wires and induction of hyperemia, making it less invasive. This ease of use overcomes many limitations associated with invasive methods, streamlining the process for interventional cardiologists.
