BACKGROUND: This study was undertaken to determine the midterm outcome in patients with anomalous left coronary artery from the pulmonary artery (ALCAPA) undergoing coronary reimplantation and Takeuchi repair.
METHODS: A retrospective review of patients who had ALCAPA repair between January 2009 and December 2015. Mortality, echocardiography assessment of left ventricular function including ejection fractionand, shortening fraction, severity of mitral regurgitation, stenosis of the coronary ostium were studied retrospectively.
RESULTS: Sixteen patients were described. The mean age at the time of surgery was 22.5 ± 10.3 years (range, 9 months-35.6 years) and 2 patients were younger than 1 year old, Surgical interventions included left coronary artery reimplantation in 13 patients (81 %) and Takeuchi repair in 3 (19 %). Concomitant mitral valve repair was performed in 2 cases, no cases required mechanical circulatory support postoperatively. There was no mortality. At median follow-up of 4.6 years, EF improved from 33.2 % ±6.8 % to 60.9 % ± 8.1 % (p <0.05), mean SF from 28.5 % ± 12.1 % to 40.2 % ± 5.4 % (p <0.05). Only one patient was with moderate mitral regurgitation. All 16 cases had normal ejection fraction and shortening fraction without stenosis of the coronary ostium at last follow-up.
CONCLUSIONS: Early establishment of a 2-coronary artery achieved excellent outcomes without morbidity and mechanical circulatory support. Normal ejection fraction and shortening fraction recovered smoothly. There is no stenosis of the coronary ostium at the midterm follow-up.
