Abstract

A significant reduction in coronary flow reserve is present when the ratio of flow at rest to flow after vasodilation is less than 2 : 1. Measurement of the pressure gradient across a stenosis using a small wire transducer also can assess functional severity. Fractional flow reserve is the ratio of the distal pressure to proximal pressure after maximum vasodilation. A fractional flow reserve of less than 0.75 indicates a significant stenosis.
