Anomalous left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital heart defect accounting for 0.26% - 0.46% of congenital anomalies. Most (85%) cases are diagnosed in the first month of life with only 18-25% of patients reaching adulthood. Patients diagnosed in adulthood typically have collaterals from the right coronary artery (RCA) which provide blood flow to the left coronary artery (LCA) system. They can present with heart failure, mitral insufficiency, arrhythmias, and/or sudden cardiac death. An otherwise healthy 60 y/o female presented to an outside hospital after a witnessed cardiac arrest when leaving the gym. Bystander CPR was started, and she received 2 shocks from an automated external defibrillator for ventricular tachycardia/ventricular fibrillation (VT/VF) with return of spontaneous circulation and taken to the local ED. A CTPE showed no acute PE and a possible ALCAPA. She was transferred to our institution for further assessment by adult congenital cardiology. TTE was performed on arrival which showed a global cardiomyopathy with color flow in the myocardium consistent with extensive collateralization. CT coronary artery was performed which confirmed ALCAPA anatomy without significant CAD. The case was discussed with CT surgery, interventional cardiology and adult congenital cardiology. The decision was made for a right and left heart catheterization and cardiac MRI to plan for possible surgery. Angiography showed a large RCA with extensive collaterals filling the left coronary system and no significant disease. RHC showed a normal cardiac output with a large left to right shunt and moderate pulmonary hypertension. MRI showed a mild diffuse subendocardial ischemia with high viability of the entire left ventricle and a pulmonary to systemic flow ratio (Qp:Qs) of 2.1. The decision was made to go ahead with primary re-implantation of the LCA to the aorta, the preferred method. Ligation of the anomalous coronary artery and coronary artery bypass grafting can also be used. She was taken for surgery and tolerated the procedure well. Follow up echo is pending, but she has had no further VT/VF episodes. This case demonstrates successful re-implantation of an ALCAPA in a symptomatic adult.

Between January 2002 and December 2012, five patients (4 female) underwent corrective surgery for anomalous left coronary artery from pulmonary artery (ALCAPA). They were older than 1 year (range, 3-56 years). One of the 2 patients younger than 10 years had presented with congestive heart failure, and the other had experienced repeated episodes of lower respiratory tract infection since childhood. Of the remaining 3 adult patients, 2 had experienced angina with effort, and 1 patient had had repeated respiratory tract infections since childhood, with mild dyspnea on effort of New York Heart Association (NYHA) class II. Three patients had the anomalous left coronary artery implanted directly into the ascending aorta via coronary-button transfer, and 2 patients underwent coronary artery bypass with obliteration of the left main ostium. Two patients underwent concomitant mitral valve repair procedures, and 1 patient underwent direct closure of a perimembranous ventricular septal defect. Four patients survived the surgery, and 1 patient died because of a persistently low cardiac output. Follow-up times ranged from 3 months to 4 years. All survivors are in NYHA class I and have left ventricular ejection fractions of 45% to 60%, with moderate (n = 1), mild (n = 1), or no (n = 2) mitral insufficiency. We conclude that a few naturally selected patients with ALCAPA do survive beyond infancy and can undergo establishment of 2 coronary systems with satisfactory results.

Abstract Background Anomalous left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital disorder resulting in ischaemia and myocardial infarction which can act as a potential substrate for life-threatening arrhythmias and sudden cardiac death. Case summary A 19-year-old man was admitted to the hospital after successful resuscitation from an out-of-hospital cardiac arrest (OHCA) due to ventricular fibrillation occurring during jogging. In the diagnostic work-up of the OHCA, computed tomography identified an ALCAPA. The patient was referred to our tertiary hospital for surgical correction. Direct reimplantation of the left coronary artery in the aorta was performed. During follow-up, 24-h electrocardiogram revealed short episodes of non-sustained ventricular tachycardia (VT). The magnetic resonance imaging at initial admission showed focal wall thinning and transmural late gadolinium enhancement consistent with a previous anterolateral myocardial infarction. Therefore, the aetiology of the OHCA could be due to a scar-related mechanism and not necessarily due to a reversible cause and an implantable cardioverter-defibrillator (ICD) was considered indicated. Given the young age and the lower complication rates, a subcutaneous device was preferred over a transvenous ICD. However, as a subcutaneous ICD (S-ICD) lacks the possibility of anti-tachycardia pacing, programmed electrical stimulation (PES) was performed to test for inducibility of monomorphic, re-entrant VT. After a negative PES, an S-ICD was implanted. Discussion ALCAPA is a potential cause of OHCA in young patients. Some of these patients keep an irreversible substrate for ventricular arrhythmias despite full surgical revascularization and might be candidates for (subcutaneous) ICD implantation.
