Door-to-Balloon Time Delay in Complex Primary Angioplasty: A Case of Anomalous Origin of the Right Coronary Artery From the Pulmonary Artery (ARCAPA).

ABSTRACT: Anomalous origin of the right coronary artery from the pulmonary artery (ARCAPA) is a rare condition, with clinical presentations ranging from sudden cardiac death to heart failure, although most cases remain asymptomatic until adulthood. We report the case of a 58-year-old man who presented to the emergency department with chest pain and persistent ST-segment elevation in the lateral leads (DI and aVL) on electrocardiogram (EKG). Coronary angiography revealed a subocclusive stenosis of the ramus intermedius (RIA) of the left coronary artery. Failure to selectively engage the RCA during the procedure, together with visualization of collateral circulation on aortography, raised suspicion of ARCAPA. Primary angioplasty was performed on the RIA with the implantation of a biodegradable polymer
