Comparison of transcatheter intervention and surgical operation in pulmonary atresia with intact ventricular septum / 中华胸心血管外科杂志

ABSTRACT

Objective To compare the results of transcatheter intervention (TI) and surgical operation (SO) in the pri-mary treatment for pulmonary atrcsia with intact ventricular septum (PA/IVS). Methods From January 2006 to May 2009, 25 patients (20 male,5 female) with PA/IVS were treated. The age at treatment was from 2 days to 8 months. The body weight was from 2.1 kg to 6.7 kg. All patients had mild to moderate hypoplasia of the right ventricle (the Z-valvue of the tricuspid valve from -2 to 1.5) with tripatite right ventricle and without coronary artery-right ventricular fistula. Eight patients under-went TI and 17 patients underwent SO. Results The primary procedure was successful in 7 patients (88%) in TI group and in 16 patients (94%) in SO group. There were 2 deaths (1 in each group). There was no significant difference regarding re-sidual pulmonary stenosis between two groups. The ventilation time and the days of hospital stay were shorter in TI group than in SO group. All the survivors were followed up for 3-36 months. One patient required repeat balloon dilation in TI group. While in SO group, one required reoperation and one required balloon dilation for PS, and 2 patients were waiting for balloon dilation. Twenty-one patients have achieved complete biventricular circulation. Two patients were scheduled for Glenn shunt operation later (1 in each group). Conclusion For PA/IVS patients with mild or moderate right ventricle hypoplasia, tran-scatheter intervention is a better alternative than surgical operation in the primary treatment.
