Mid-term outcomes of surgical repair for anomalous origin of the left coronary artery from the pulmonary artery: In infants, children and adults

BACKGROUND Anomalous origin of left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital malformation. We sought to evaluate in-hospital and mid-term outcomes of patients with a diagnosis of ALCAPA who underwent surgical repair. OBJECTIVES The objective of this study is to evaluate the mid-term outcomes of surgical repair of ALCAPA at our center and to analyze the surgical techniques used. MATERIALS AND METHODS In a retrospective study, we analyzed early and mid-term clinical and echocardiographic data to determine the outcomes of patients who underwent surgical repair of ALCAPA in our institution between 2005 and 2015. RESULTS Twenty-one patients underwent surgical repair for ALCAPA using aortic reimplantation (n = 10, 47.6%), ostial closure (n = 8, 38.1%), or ligation (n = 3, 14.3%). The median age of patients was 24 months (range 22 days to 51 years). There were 2 (9.5%) in-hospital mortalities in infants undergoing the reimplantation technique. All patients were followed up for a median of 21 months (range 1-60 months). No patients required reoperation, and there was no mortality from discharge to mid-term follow-up. Severe early postoperative mitral regurgitation (MR) was associated with composite end-point, defined as a combination of mortality after surgery, moderate to severe MR, and moderate to severe left ventricular dysfunction at late follow-up (P = 0.019) while mitral valve repair was not (P = 0.469). CONCLUSION The surgical management of ALCAPA can be associated with good in-hospital and mid-term outcomes regardless of the age, at which the patient has been operated.
