ABSTRACT

Objective:

To explore the anatomic repair strategy for congenital corrected transposition of great arteries (ccTGA).

Methods:

At the retrospective study, from August 2004 to May 2019, all 120 consecutive ccTGA were included and all accepted anatomic repair. There were 36 cases with with left ventricular outlet obstruction(LVOTO) and cardiac malpositon [ages(4.6±2.2) years, weight(17.7±5.9)kg] underwent the one and a half ventricle repair(hemi-Mustard and bidirectional Glenn procedures combined with the Rastelli), 49 cases[ages(3.4±2.7) years, weight(17.7±11.4)kg] underwent double switch operation(Great artery swtich with Senning operation), 24 cases [ages(5.7±4.3) years, weight(19.1±8.6)kg] with LVOTO and ventricular sept defect(VSD) accepted the Rastelli with Senning operation, and 14 cases with LVOTO and remote VSD [ages(6.9±4.8) years, weight(23.0±12.9)kg] accepted the Double root transposition(DRT) with Senning operation. Follow up data were collected by telephone interviews and echo. The median follow-up time were 49 months varied from 20 to 84 months, 46 months varied from 18 to 108 months, 35 months varied from 7 to 84 months and 98 months varied from 72 to 145 months. Statistical analysis was performed with SPSS 19.0.

Results:

There were 6 in-hospital deaths and 2 follow-up deaths. The survival probability were(84.0±6.0)% and(84.0±6.0)% at 5 and 10 years after operation. The probability of freedom from re-intervention were(95.0±11.8)% and(89.0±11.8)% at 5 and 10 years after operation. All 6 patients need implant pacemaker for Ⅲ A-V block. Seven patients had moderate or more than moderate tricuspid regurgitation. The left ventricular(systemic ventricle) EF were 0.61±0.09, 0.63±0.08, 0.59±0.01 and 0.65±0.07 in one and a half ventricle repair group, double switch(AS group), Rastelli with Senning(RS group) and DRT with Senning(DS group) patients. There were 1 heart failure in one and a half ventricle repair group, 1 in AS group and 1 in RS group. For 36 pure ccTGA patients, compared with direct double switch patients these patients accepting double switch after pulmonary banding(PAB) had more EF(0.54±0.09 vs. 0.65±0.08, P=0.00). There were significantly less patients need re-operation in one and a half ventricle repair group compared with RS group(0 vs. 13.6%, P=0.03).

Conclusion:

For ccTGA/LVOTO/cardiac malpositon, the one and a half ventricle repair was ideal strategy with significant less RV-PA conduit stenosis and re-operation. For pure ccTGA patients, second staged double switch after PAB had better long-term heart function. For ccTGA/ LVOTO/ remote VSD patients DRT with Senning was ideal strategy.
