Fractional flow reserve FFR is a well-established invasive tool to assess the physiologic significance of a coronary stenosis.

Fractional flow reserve is defined as the pressure after a stenosis relative to the pressure before the stenosis. Its role is to provide information that can more appropriately select patients requiring invasive coronary. The original description of FFR required the induction of maximal hyperemia to achieve near linear correlation between coronary pressure and blood flow.

Fractional Flow Reserve Market PPT 2021-2026. Several randomized trials proved the safety of deferring revascularization based on FFR in subjects with stable coronary artery disease with single or multivessel disease. Fractional flow reserve FFR and instantaneous wave-free ratio are the present standard diagnostic methods for invasive assessment of the functional significance of epicardial coronary stenosis.
