Early Detection of Anomalous Origin of Left Coronary Artery from the Right Pulmonary Artery After Successful Repair of Critical Coarctation of the Aorta

摘要

Left ventricular (LV) function is impaired by increased afterload in neonates with severe coarctation of the aorta, which may result in endocardial fibroelastosis. Repair of the coarctation usually solves the problem, with LV function normalizing after a few weeks. This report describes a patient who underwent successful repair of critical coarctation with normalization of LV function despite signs of endocardial fibroelastosis but with persisting elevation of cardiac troponin T. Cardiac catheterization showed the rare coincidence of anomalous origin of left coronary artery from the right pulmonary artery (ALCAPA) and coronary sinus orifice atresia with left superior vena cava. Keywords ALCAPA - Cardiac troponin T - Coarctation of the aorta - Coronary sinus orifice atresia
