Figure 1. The transition of the physiological parameters throughout the procedure. Baseline coronary angiogram (A), fractional flow reserve (B), and diastolic pressure ratio (C). Post atrioventricular (AV) branch intervention coronary angiogram (D), fractional flow reserve (E), and diastolic pressure ratio (F). Final coronary angiogram (G), fractional flow reserve (H), and diastolic pressure ratio (I).

A 68-year-old man with exertional angina was admitted to our hospital. Coronary angiography revealed a moderate stenosis in the mid right coronary artery (RCA) and an occluded atrioventricular (AV) branch with Rentrop grade 2 collaterals providing retrograde flow from the posterior descending (PD) branch (Figure 1...
