Anomalous left coronary artery from pulmonary artery (ALCAPA) as a silent cause of mitral regurgitation in children

Abstract

Anomalous left coronary artery from pulmonary artery (ALCAPA), also known as Bland-White-Garland syndrome, is a rare cardiac disease. This condition may present with complications such as myocardial infarction, left ventricular dilatation, mitral regurgitation, and left heart failure in children. We report a case of a four-year-old boy who presented with shortness of breath, palpitations, and recurrent upper respiratory tract infections. He was diagnosed with mitral regurgitation. During the surgery, left coronary artery (LCA) was not present in its anatomical position and ALCAPA was identified. One should keep in mind the possibility of ALCAPA in presentation of mitral regurgitation in children despite not being reported in echocardiography.
