      Objective: To evaluate the efficacy of reconstruction of right ventricular outlet tract(RVOT)with 0.1 mm Gore-Tex monocusp valve for short term.
      Methods: Between June 2002 to June 2010, 75 patients (42 male, 33 female) underwent reconstruction of RV0T with Gore-Tex monocusp valve to
correct cardiac anomalies,including 57 patients with tetralogy of Fallot (TOF) and pulmonary stenosis, 10 patients with TOF and pulmonary atresia,
4 patients with TOF and absent pulmonary valve, 2 patients with double outlet of right ventricle and pulmonary stenosis, 1 patient with truncus arterious
and 1 patient with complete transposition of great artery, ventricular septal defect and pulmonary stenosis.
      Results: There was no operative death. The postoperative blood oxygen saturation was up to 96%-100%. PaO2 was 82-207mmHg. The ratioes of right
ventricular systolic pressure and left ventricular systolic pressure were between 0.22 to 0.70.The gradient between right ventricle and left or right pulmonary
artery was less than 10 mmHg; Left ventricular ejection fraction (LVEF) was 0.53-0.80, right ventricular ejection fraction (RVEF) was 0.52-0.71, left
ventricular end-diastolic volume index was 0.28-0.62ml/m2. Early postoperative complications: hypoxemia (oxygenation index <150) in 6 cases, low cardiac
output syndrome in 4 cases, arrhythmia in 5 cases, 7 cases pericardial effusion, 4 cases of residual ventricular septal defects. All patients were followed up
including echocardiography ranged from 3 to 48 months. There were no late death and complications. 62 cases early valve activities function was normal, 13
patients single lobe fixed in the open state, 72 patients were not pulmonary stenosis, 3 patients mild stenosis; 21 cases mild pulmonary valve regurgitation , 5
cases moderate regurgitation.
      Conclusion: The results suggest that reconstruction of RVOT with 0.1 mm Gore-Tex monocusp valve can secure a satisfactory clinical and
hemodynamic effects of the recent good results.Strict,intensive surveillance and promptly synthesized treatment for low cardiac output syndrome,
cardiac arrhythmia can improve the operative results, Early therapy may effectively avoid negative consequence of postoperative serious complication.
