  • The operative strategy after palliative shunt for corrected transposition of great artery (cTGA) with left ventricular outflow tract obstruction and cardiac malpostion

    ObjectiveTo explore the operative strategy after palliative shunt for correcting congenitally corrected transposition of great artery (cTGA) patients with left ventricular outflow tract obstruction (LVOTO) and cardiac malpostion.MethodsWe retrospectively analyzed the clinical data of 54 patients with onsecutive cTGA with LVOTO and cardiac malpositon from June 2011 to May 2019. The patients were devided into two groups. There were 24 patients (16 males and 8 females at mean age of 5.4±2.2 years) who underwent one and a half ventricle repair as a one and half ventricle group. And there were 30 patients (19 males and 11 females at age of 8.6±6.2 years) who underwent one ventricle repair operation as a one ventricle group. Follow-up data were collected by telephone interviews.ResultsThere was no statistical difference in systemic atrioventricular valve regurgitation and systemic ventricular ejection fraction between the two groups (P>0.05). Compared with one and a half ventricle group, the cardiopulmonary bypass time (CPB) time, mechanical ventilation time and intensive care unit stay were significant shorter than those in the one ventricle group (P<0.05), but prolonged pleural effusions developed more frequently in the one ventricle repair group (P<0.05). There was no in-hospital death but 1 follow-up death in each group. The follow-up time was 49 (17-38) months in the one and half ventricle group at follow-up rate of 93.9%, and 47 (12-85) months at follow-up rate at 90.9% in the one ventricle group. One and a half ventricle group had better systemic ventricular ejection fraction (EF) than that in the one ventricle repair group. And the rate of heart function (NYHA) class Ⅲ and class Ⅳ in one and a half ventricle group was lower than that in the ventricle group. No significant difference of survival and freedom from re-intervention probability between the two groups was found.ConclusionFor patients of correction of cTGA with LVOTO and cardiac malposition after palliative shunt, the one-and-a-half ventricular repair procedure is ideal operative strategy.
