Anomalous origin of the left coronary artery from the pulmonary artery-adult type with heart failure and ventricular arrhythmia presentation

Abstract

Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) syndrome is a rare congenital anomaly occurring in 1 of 300,000 births. As it has high mortality rate during the 1st year of life, adult type is very rare. Arrhythmias, heart failure, myocardial infarction, and sudden cardiac death are common presentations of ALCAPA syndrome in adults. Here, we report a 28-year-old male with malignant ventricular arrhythmia and sudden cardiac death. ALCAPA syndrome was diagnosed by coronary angiography and echocardiography; finally, cardiac surgery was performed with a good result.
