ABSTRACT
Objective:To summarize the surgical treatment result in patients with anomalous left coronary artery from pulmonary artery (ALCAPA) combining severe left ventricular dysfunction.Methods:A total of 24 ALCAPA patients combining severe left ventricular dysfunction received coronary reimplantation in our hospital from 2009-02 to 2016-04 were retrospectively studied.The patients' mean age was 7.0 (5.0,17.8)months including 13 male;mean left ventricular ejection fraction (LVEF)＜30％ and the median pre-operative LVEF was 21.0％ (17.3％,26.5％).Results:There were 2/24 (8.3％) in-hospital death,The median cardiopulmonary bypass time was 109 (95,128) min,aorta cross-clamp time 65 (48,87) min,mechanical ventilation time 94.5 (48.3,165.5) h and ICU stay time 176.5 (101.0,305.3) h;2 patients received ECMO support and weaned off successfully and 2 patients received re-intubation.In 22 survival patients,the median discharge LVEF was 26.0％ (20％,35％) which was similar to pre-operative condition,P＞0.05.The mean follow-up time was (15.3±14.9) months at the longest of 63 months,no re-admission,reoperation and death occurred.The patients had NYHA I and the last follow-up LVEF was 60％ (50％,69％) which was increased than discharge level,P＜0.05,4 patients had LVEF＜50％.Conclusion:Surgical treatment had satisfactory short-and mid-term outcomes in ALCAPA patients combining severe left ventricular dysfunction;comprehensive effort should be emphasized in surgery,anesthesia,cardiopulmonary bypass and ICU management at peri-operative period.
