The caveats in the diagnosis of anomalous origin of left coronary artery from pulmonary artery (ALCAPA).

Abstract

Anomalous origin of left coronary artery from pulmonary artery (ALCAPA) is an infrequent, well described, but important anomaly of the coronary origin. Early diagnosis and prompt surgical treatment of the disease can be life saving. However, there are several potential sources of error in the seemingly simple stereotype diagnostic pattern. We report a case of ALCAPA and allude to some of the caveats in the diagnosis of this entity.
