Surgical Outcomes for Children with Anomalous Origin of the Left Coronary Artery from the Pulmonary Artery.

Objective of this study is to summarize surgical outcomes of patients with anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) in a single center. The clinical data of 89 children undergoing surgical treatment in Beijing Children's Hospital from January 2007 to January 2022 were retrospectively analyzed. seven patients underwent ECMO support for acute left heart failure after operation, and 2 patients were discharged after weaning successfully. Eight patients died in the early postoperative period, all of them were infants, of which 5 patients underwent ECMO support, 2 patients died of cerebral hemorrhage, 2 patients died of multiple organ dysfunction, and 4 patients died of left heart failure. Three patients died late, 3 patients were lost to follow-up, and 78 patients (96.3%) completed long-term follow-up. A logistic regression model multivariate analysis showed that postoperative moderate or severe mitral regurgitation (MR) (OR 26.948 P = 0.024) and prolonged aortic cross-clamp time (OR 1.038 P = 0.050) were independent risk factors of early mortality. Compared with the Non-MVP group (20/36), the MVP group (patients with moderate or severe MR who underwent MVP at the same time) (16/36) had more significant improvement in early postoperative LEVEF [(50.68 ± 13.85)% vs (40.50 ± 13.58)% P = 0.033] and had a lower proportion of moderate or severe MR after operation (2/16 vs 11/20 P = 0.014). Children with ALCAPA can obtain a good prognosis by reconstructing the blood supply of both coronary arteries. Mitral valvuloplasty (MVP) is more helpful in improving the prognosis of children with moderate or severe MR and mitral valve structural disease. Reasonable placement of ECMO can help reduce the mortality of critically ill children after operation, but be alert to complications in the central system.
