The role of multimodality imaging in diagnosing an adult-type anomalous origin of the left coronary artery from the pulmonary artery: A case report.

Anomalous origin of the left coronary artery from the pulmonary artery is a rare congenital coronary anomaly. This case report describes an adult male with anomalous origin of the left coronary artery from the pulmonary artery, in whom transthoracic echocardiography revealed mitral valve prolapse without apparent anomalies of the coronary ostia. The definitive anatomical diagnosis was established using invasive coronary angiography and coronary computed tomography angiography. This case underscores the indispensable value of multimodality imaging in the diagnosis of anomalous origin of the left coronary artery from the pulmonary artery.
