Objective To investigate the surgical indications and the mid and long term results of morphologic tricuspid valve replacement for corrected transposition of the great arteries(cTGA). Methods From September 1997 to September 2007, 18 cases with cTGA were treated in Fu Wai Hospital. There were 15 male and 3 female, aged from 16 to 51 years(33.3±12.8 years), and weighed from 47 to 90 kg(60.9±14.7 kg). There were 10 cases with isolated morphologic tricuspid valve insufficiency, 3 complicated with ventricular septal defect, 2 complicated with ventricular septal defect and pulmonary valve stenosis, 2 with morphologic tricuspid valve insufficiency after septal defect repair, and 1 with mechanical valve dysfunction after morphologic tricuspid valve replacement. The preoperative mean morphologic right ventricle ejection fraction was 562%±11.6%. Of the 18 cases, 12 were in grade Ⅱ and 6 were in grade Ⅲ according to New York Heart classification(NYHA).All the cases had undergone morphologic tricuspid valve replacement. Postoperative indices such as cardiac function and morphological right ventricle ejection fraction were followed up. Results One patient died of postoperative low cardiac output syndrome. Two had pervavlvular leak, which were cured by pervavlvular leak repair at 7th and 30th day after operation, respectively. Sixteen were followed up with a followup time of 57.0±407 months. There was no statistical significance between preoperative and postoperative mean morphologic right ventricle ejection fraction(52.8%±9.2% vs.56.2%±11.6%; t=2.062, P gt;0.05). The followup showed that 12 were in NYHA grade Ⅰ or Ⅱ, and 4 were in NYHA grade Ⅲ. There was no statistical significance between preoperative and postoperative percentage of cases in NYHA grade Ⅲ(χ2=1.532,P gt;0.05). Conclusion Morphologic tricuspid valve replacement can prevent the further damage to morphologic right ventricular function caused by morphologic tricuspid valve insufficiency. The mid and long term results were satisfying. During the followup, the morphologic right ventricle can function appropriately.
