Anomalous origin of the left coronary artery from the pulmonary artery presenting as dilated cardiomyopathy

Abstract

Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital anomaly and one of the causes of myocardial ischemia. It often presents with atypical signs and symptoms, especially in childhood. In this case report, an 11-year-old girl presented with dilated cardiomyopathy in our clinic and was followed for five years. Echocardiography showed multiple left-to-right shunts on the interventricular septum, the confirmation of which was done by multi-slice computed tomography and coronary angiography. Therefore, we suggest that ALCAPA should be suspected in young patients diagnosed with dilated cardiomyopathy.

Anomalous origin of coronary artery: taxonomy and clinical implication

“…Anomalous origin of left coronary artery from the pulmonary artery is a rare congenital anomaly and one of the causes of myocardial ischemia. Due to atypical signs and symptoms in childhood, it can be misdiagnosed as dilated cardiomyopathy [ 54 ] . The definitive diagnosis can be reached by multislice computed tomography and coronary angiography [ 55 ] .…”
