Abstract
<jats:p>Anomalous Origin of the Right Coronary Artery from the Pulmonary Artery (ARCAPA), or abnormal origin of the Right Coronary Artery (RCA) from the main pulmonary artery, is an uncommon congenital coronary anomaly, occurring in fewer than 0.1% of all congenital heart defects and significantly less frequent than Anomalous Origin of the Left Coronary Artery from the Pulmonary Artery (ALCAPA). Myocardial infarction and sudden cardiac death are potential complications, even in asymptomatic individuals. The authors hereby, present a case of a 12-year-old boy who presented with recurrent episodes of giddiness, particularly during prolonged standing. Echocardiography and Coronary Computed Tomography Angiography (CCTA) confirmed the diagnosis of ARCAPA, demonstrating an anomalous origin of the RCA from the Main Pulmonary Artery (MPA) along with mild dilatation of the left atrium and left ventricle. The patient underwent successful surgical repair involving translocation of the right coronary artery from the main pulmonary artery to the aorta. The postoperative outcome was excellent, with stable haemodynamics.</jats:p>
