ABSTRACT
@#Objective    To analyze the early outcomes of anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) patients with severe left ventricular dysfunction after surgical repair, and to explore the predictors for extracorporeal membrane oxygenation (ECMO) support for these patients. Methods    The clinical data of ALCAPA patients with severe left ventricular dysfunction (left ventricular ejection fraction<40%) who underwent coronary artery reimplantation in the pediatric center of our hospital from 2013 to 2020 were retrospectively analyzed. The patients were divided into an ECMO group and a non-ECMO group. Clinical data of the two groups were compared and analyzed. Results    A total of 64 ALCAPA patients were included. There were 7 patients in the ECMO group, including 4 males and 3 females aged 6.58±1.84 months. There were 57 pateints in the non-ECMO group, including 30 males and 27 females aged 4.34±2.56 months. The mortality of the patients was 6.25% (4/64), including 2 patients in the ECMO group, and 2 in the non-ECMO group. The postoperative complications rate was significantly higher in the ECMO group than that in the non-ECMO group (P=0.041). There were statistical differences in the cardiopulmonary bypass time [254 (153, 417) min vs. 106 (51, 192) min, P=0.013], aortic cross-clamping (ACC) time (89.57±13.66 min vs. 61.58± 19.57 min, P=0.039), and preoperative left ventricular end-diastolic diameter/body surface area (132.32±14.71 mm/m2 vs. 108.00±29.64 mm/m2, P=0.040) between the two groups. Multivariate logistic regression analysis showed that ACC time was an independent risk factor for postoperative ECMO support (P=0.005). Receiver operating characteristic (ROC) curve analysis showed that the area under the ROC curve was 0.757, the sensitivity was 85.70%, specificity was 66.70%, with the cut-off value of 66 min. Conclusion    ACC time is an independent risk factor for postoperative ECMO support. Patients with an ACC time>66 min have a significantly higher risk for ECMO support after the surgery.
