Abstract
Between April 68 and May 91, 59 patients underwent total correction fordouble-outlet right ventricle. The mean age was 59.2 +/- 7.8 months. Thehospital mortality rate was 27%; it was 41% before 1980 and 13% thereafter.Low cardiac output failure was the leading cause of early death. Myocardialprotection without cardioplegia and long cardiopulmonary bypass time weresignificant predictors of hospital mortality in univariate as well as inmultivariate analysis. The late death rate was 7%. The actuarial survivalrate was 67% (CL 55-80%) after 10 and 20 years. The reoperation rate was42%, a loose VSD patch constituted the main indication (23%). The actuarialfreedom from reoperation rate was 51% (CL 33%-69%) after 10 years and 31%(12%-50%) after 20 years. The mean follow-up time was 8.4 +/- 0.9 years (2to 20 years). Seventy-five percent of all postoperative survivors are inNYHA functional class I and left ventricular ejection fraction is normal in82%.Keywords
