Imaging findings
CT angiography shows the left main coronary artery arising directly from the pulmonary artery (ALCAPA). There is massive dilatation and tortuosity of the right coronary artery with extensive septal collateral vessels, along with an aneurysmal out-pouching of the left ventricular apex.
Key takeaways
Anomalous left coronary artery from the pulmonary artery (ALCAPA) is a congenital anomaly that usually presents in infancy with myocardial ischemia. Rare patients survive to adulthood due to the development of massive intercoronary collaterals. Over time, chronic ischemia can lead to left ventricular apical aneurysm and dysfunction.
