Abstract: Objective:To review the shortterm result of surgical treatment of child patients with anomalous left coronary artery from the pulmonary artery（ALCAPA）.Methods:A retrospective，single institution review was conducted on 86 child patients with ALCAPA underwent coronary reimplantation.All the patients underwent coronary reimplantation procedure with cardiopulmonary bypass.Patients with moderate or severe MR underwent mitral valve repair simutanously.To evaluate the short outcome of coronary reimplantation and MVP surgery，we analyze the related factors during the surgery and perioperative recovery.Results:There were two inhospital deaths.The median cardiopulmonary bypass time and crossclamp time were 112.0min（95.0～141.0min）and 73.0min（57.0～91.5min）,respectively.The median mechanical ventilation time and intensive care unit time were 22.0h（8.0～93.0h） and 69.0h（24.0～168.0h），respectively.Three patients underwent ECMO support and weaned off successfully.The median postoperative LVEF 55.0%（34.3～65.0%）did not improved compared with the preoperative LVEF.The LVEDD 34.5mm（27.0～38.0mm）decreased significantly compared with preoperative LVEDD（P<0.05）.in the patients with LVEF<50%，the postoperative LVEF increased significantly[（35.5%（26.0～42.0%） vs 25.0%（19.0～35.0%）]，P<0.05）.No patient with severe MR and ten patients with moderate MR when were discharged.Conclusion:The coronary reimplantation has a satisfactory shortterm result for child patients with ALCAPA.
