Different Presentation of Anomalous Origin of the Left Coronary Artery from the Pulmonary Artery in Adults: Case Reports

Abstract

Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital cardiac malformation. We report three cases of ALCAPA who survived to adulthood. The first case was a 51-year-old woman who complained of typical chest pain that was diagnosed with ALCAPA using cardiac catheterization and coronary computed tomographic angiography (CTA). The second case was a 30-year-old woman with a history of surgery for atrial septal defect at 10 years old who presented with progressive exertional dyspnea. Cardiac catheterization confirmed the diagnosis of ALCAPA. The third case was a 19-year-old man who was brought to our clinic due to aborted sudden cardiac death on the previous day. Cardiac catheterization and coronary CTA confirmed the diagnosis. They underwent the closure of orifice of the anomalous left coronary artery and grafting the left anterior descending artery concomitantly with mitral valve repair. All patients were followed up during a mean of 8.7 months and they were asymptomatic.
