AbstractAnomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital heart lesion that if left untreated, results in high mortality. Surgical treatment options include reimplantation of the anomalous coronary ostia, use of extracardiac arterial blood supply, or the Takeuchi procedure. The Takeuchi procedure involves creation of an aortopulmonary window and an intrapulmonary tunnel that baffles the aorta to the ostium of the anomalous left coronary artery. The incidence of late complications following the Takeuchi repair is unknown. The goal of our study was to determine the long-term outcome after palliation of ALCAPA using the Takeuchi Procedure. A total of 9 patients with a history of ALCAPA palliated with the Takeuchi procedure were identified from our surgical database. Chart review was performed. The mean age at time of Takeuchi procedure was 49.6 months (range 5 weeks-14.6 years). There was one late death, of unknown cause. Of the remaining 8 patients, the mean length of follow-up after surgery was 15.9 years (13.5-19.7 years). All 8 survivors had some degree of main pulmonary artery stenosis in the area of the intrapulmonary baffle, with moderate stenosis in 2 and severe stenosis in 1. Three late survivors (38 %) had a baffle leak. Two patients (25 %) had decreased left ventricular systolic function and 3 (38 %) had developed at least moderate mitral valve regurgitation. Three of the 8 late survivors (38 %) required a reoperation for repair of mitral valve regurgitation, baffle leak, and main pulmonary artery (MPA) stenosis. Review of literature demonstrated similar complication rates and need for reoperation following the Takeuchi procedure. Compared with patients after direct reimplantation for ALCAPA at our institution, there was no significant difference in late survival or freedom from reoperation. The Takeuchi procedure is a method to establish a two-coronary repair for ALCAPA. Late complications are common, necessitating lifelong care in a center experienced with caring for adults with congenital heart disease.
