摘要

BACKGROUND Treatment of congenitally corrected transposition of great arteries(cc-TGA)with anatomic repair strategy has been considered superior due to restoration of the morphologic left ventricle in the systemic circulation.However,data on long term outcomes are limited to single center reports and include small sample sizes.AIM To perform a systematic review and meta-analysis for observational studies reporting outcomes on anatomic repair for cc-TGA.METHODS MEDLINE and Scopus databases were queried using predefined criteria for reports published till December 31,2017.Studies reporting anatomic repair of minimum 5 cc-TGA patients with at least a 2 year follow up were included.Metaanalysis was performed using Comprehensive meta-analysis v3.0 software.RESULTS Eight hundred and ninety-five patients underwent anatomic repair with a pooled follow-up of 5457.2 patient-years(PY).Pooled estimate for operative mortality was 8.3%[95%confidence interval(CI):6.0%-11.4%].0.2%(CI:0.1%-0.4%)patients required mechanical circulatory support postoperatively and 1.7%(CI:1.1%-2.4%)developed post-operative atrioventricular block requiring a pacemaker.Patients surviving initial surgery had a transplant free survival of 92.5%(CI:89.5%-95.4%)per 100 PY and a low rate of need for pacemaker(0.3/100 PY;CI:0.1-0.4).84.7%patients(CI:79.6%-89.9%)were found to be in New York Heart Association(NYHA)functional class I or II after 100 PY follow up.Total re-intervention rate was 5.3 per 100 PY(CI:3.8-6.8).CONCLUSION Operative mortality with anatomic repair strategy for cc-TGA is high.Despite that,transplant free survival after anatomic repair for cc-TGA patients is highly favorable.Majority of patients maintain NYHA I/II functional class.However,monitoring for burden of re-interventions specific for operation type is very essential.
