Abstract:
Objective To analyze the clinical characteristics of complete transposition of great arterial with left ventricular outflow tract obstruction(TGA/LVOTO) patients who received arterial switch operation(ASO),and further evaluated the risk factors of postoperative adverse events.Methods Retrospectively evaluated the adverse events(including postoperative mortality,reoperation,aortic valve insufficiency,re-LVOTO and mitral valve insufficiency) and the related risk factors of 39 TGA/LVOTO patients after ASO.Results 39 TGA/LVOTO patients were included,the mean Z value of PV was 0.6,the mean peak LVOT gradient was 31.6 mmHg (1 mmHg =0.133 kPa).The mean follow up time was 15.9 months,during the follow up,1 patient had early mortality,and CPB time(P =0.034) was associated with early mortality;4 patients had early reintervention;15 patients had AVI,and larger PV Z value(P =0.026) was associated with postoperative AVI;7 patients had MVI,and subvalvar level LVOTO(P =0.001) was associated postoperative MVI;6 patients had re-LVOTO,and older age at operation (P =0.029),muhi-level LVOTO (P =0.024) were associated with postoperative re-LVOTO.Conclusion If the obstruction of LVOT can be repaired by surgery,TGA/LVOTO patients had a satisfied prognosis after ASO with relief of LVOTO,the postoperative early mortality was very low,and although the probability of re-LVOTO was increased with time,the long-term reintervention probability was very low.
