Abstract:
Objective To discuss clinic effect of pulmonary artery valvuloplasty for right ventricle outflow tract (RVOT) reconstruction in patients with repaired tetralogy of fallot (TOF). Methods A total of 93 cases TOF were randomly divided into Group A (n = 49) or Group B (n = 44) to perform the procedure with repaired tetralogy of fallot Group A received autogenous pericardium to enlarge RVOT and pulmonary valvuloplasty.Group B received autogenous pericardium to enlarge RVOT by routine therapy. Pulmonary regurgitation index (PRi) and the ratio between pulmonary regurgitant jet width and pulmonary annulus diameter were measured with echoeardiography. Results The mean follow-up was 3. 1 ± 0. 2 years. The PRi and the ratio between pulmonary regurgitant jet width and pulmonary annulus diameter in Group A were-significantly lower than Group B (0. 55 ± 0. 13 vs. 0. 61 ± 0. 10, t = 2. 685, P < 0.01) and ([52.0 ± 10.4] % vs. [57.1 ± 10. 5]% ,t = 2. 349, P < 0.05) . Three-dimensional ultrasound examination showed that 69% (34/69) of pulmonary valves in Group A was developed well. Conclusion Pulmonary valvuloplasty during transannular patch for repaired TOF may prevent fre'e pulmonary regurgitation and can obtain good clinical outcome.
