Abstract:
Objective: To investigate the result of biventricular repair for double outlet right ventricle without pulmonary stenosis. Methods: From January 1975 to June 2003, 38 consecutive patients underwent biventricular repair for double outlet right ventricle without pulmonary stenosis. At surgery, the median age of this group was 5.8 years. Two types of repair techniques were applied: intraventricular baffle repair (n=36) and arterial switch operation with VSD to pulmonary artery baffle (n=2). Results: There were 5 hospital deaths, with mortality rate of 13 2%. Two of these patients died of pulmonary hypertension crisis and the other 3 died of low cardiac output syndrome. One case (2 6%) died of right heart failure on 95th day postoperatively. The follow up periods in 29 patients (76%) ranged from 1 month to 23 years. 19 cases (65.5%) of these patients were in NYHA class I, 9 (31.0%) in NYHA class II, and the 1 (3.5%) in NYHA class III. Conclusion: The biventricular repair might be an effective treatment for double outlet right ventricle without pulmonary stenosis is good. Operation should be performed as early as possible before the development of progressive pulmonary vascular disease.
