Intramural Coronary Length Correlates With Symptoms in Patients With Anomalous Aortic Origin of the Coronary Artery

Symptomatic patients had a longer intramural course than asymptomatic patients, as assessed by preoperative imaging and intraoperative measurements. These results may have important clinical implications in determining indications for operation.
