FFR and non-hyperaemic pressure ratios

Moderators: M. Götberg, R. Bagur

Summary

This session presents contemporary clinical applications of fractional flow reserve (FFR) and non-hyperaemic pressure ratios (NHPR), highlighting real-world impacts of physiology microcatheter-based indices, the interplay between epicardial stenosis and microvascular resistance, post-PCI hyperemia effects on iFR, and machine-learning driven outcome predictions.
