Long-term results of right ventricular outflow tract reconstruction with an allograft conduit

Abstract

Objective: To evaluate the long-term results of right ventricular outflow tract (RVOT) reconstruction with allograft conduits. Methods: From January 1988 to December 1997, a total of 165 patients underwent reconstruction of RVOT with allograft conduit 136 aortic conduits and 29 pulmonary conduits. The mean age of patients was 7.6 years (rang, 1.3 to 22 years). The mean body weight was 22.0 kg (range, 9.5 to 58.0 kg). The mean conduit was 19 mm (range, 17 to 22 mm). Results: The operative mortality rate was 20%(34/165). The mean follow up was (37.0±8.6) months (range, 10 months to 12.1 years). 5-and 10-year survival rates were 94.6% and 83.8%, respectively. Allograft functioning rates at 5 and 10 years were 83% and 58%, respectively. Conclusion: The satisfactory long-term results could be achieved in using reconstruction of RVOT allograft conduit in the treatment of complicated congenital heart disease.
