Abstract

Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA), which has also been termed Bland-White-Garland syndrome, is a rare congenital anomaly of the coronary artery that accounts for 0.25–0.5% of all congenital cardiac malformations. Although computed tomographic coronary angiography allows for the evaluation of the connection and anatomy of ALCAPA, procedural details have not yet been reported. This case report describes how the appropriate dose and duration of contrast medium administration were determined, as well as the optimal direction of image acquisition to allow the most detailed anatomical visualization of the ALCAPA.
