Is exercise stress testing useful for risk stratification in anomalous aortic origin of a coronary artery?

Data on maximal exercise-stress-testing (m-EST) in anomalous-aortic-origin-of-coronary-arteries (AAOCA) is limited and correlation with stress perfusion imaging has not been demonstrated. AAOCA patients ≤20 years were prospectively enrolled from 6/2014-01/2020. A m-EST was defined as heart rate>85%ile on ECG-EST and respiratory-exchange-ratio (RER) ≥1.05 on cardiopulmonary-exercise-testing (CPET). Abnormal m-EST included significant ST-changes or high-grade arrhythmia, ໿V̇O2max and/or O2 pulse
