An 11-Year-Old Athlete With Dynamic Stenosis of Coronary Artery Anomaly With Normal FFR-Dobutamine But Abnormal iFR-Dobutamine
Anomalous aortic origin of a right coronary artery (R-AAOCA) can cause stress-induced ischemia owing to dynamic stenosis of the intramural course. While fractional flow reserve during dobutamine challenge (FFRDobutamine) is the reference standard for hemodynamic assessment, specific scenarios favoring instantaneous wave-free ratio (iFR) over FFR remain unclear.
