The role of multimodal imaging in the diagnosis of an asymptomatic patient with congenital anomaly.

Anomalous left coronary artery from the pulmonary artery (ALCAPA) syndrome is a rare congenital coronary anomaly, which can cause potentially fatal complications, such as heart failure, myocardial infarction and sudden cardiac death. Only a few patients left untreated survive to adulthood. We highlight the importance of multimodal imaging in the diagnosis of ALCAPA syndrome in a young asymptomatic female patient with inducible ischemia on exercise. The patient was successfully treated with surgery.
