Abstract
The assessment of FFR for a single stenosis may also be rapid and not require hyperemia if the Pd/Pa gradient already reaches significance before the vasodilator is administered. In this case the resting Pd/Pa was 0.45, demonstrating that the stenosis was relevant even before hyperemia was achieved.
