摘要:
Background The prognosis of tetralogy of Fallot with absent pulmonary valve (TOF/APV) without operation is poor. We evaluated the surgical outcome of TOF/APV in a single center. Methods Twenty-two TOF/APV patients underwent complete surgical correction in our hospital. Right ventricular outflow tract reconstruction was performed using bovine jugular vein (BJV)-valved conduit implantation (n=10), homograft-valved conduit implantation (n=2), or monocusp-valve patch (n=10). Health-related quality of life (QOL) was evaluated during follow-up. Results The overall survival at 5 and 10 years was 86.47.3% (confidence interval 69.4-97.2%). The survival rates were significantly different between patients with and without bronchial stenosis (40 and 100%, P=0.0003, log-rank test). The survival of patients aged>6months was higher than those <= 6months (100 vs. 40%, P=0.0003, log-rank test). Patients with BJV-valved conduits had higher systolic gradients from the right ventricle to the pulmonary artery (RV-PA) compared to those with monocusp-valve patches. BJV-valved conduit implantation was a risk factor for post-operative pulmonary-valve stenosis. The QOL score for patients with BJV-valved conduits was lower than those with monocusp-valve patches (P<0.05). No reoperation was performed during follow-up. Conclusions Bronchial stenosis and lower age (<= 6months) were the main factors influencing post-operative survival. The use of a BJV-valved conduit was a main reason for RV-PA restenosis; thus, the use of a BJV-valved conduit may increase the need for repeat intervention and decrease the post-operative quality of life.
