Anomalous aortic origin of the right coronary artery with functional ischemia determined with fractional flow reserve derived from computed tomography

Abstract

A right coronary artery of anomalous origin is rare congenital anatomy that can be fatal. CT angiography is an excellent tool for its anatomical assessment. Noninvasive CT-based fractional flow reserve measurement can additionally evaluate the functional severity of coronary stenosis and is potentially useful for evaluating coronary anomalies.
