From March 1977 through May 1985, 33 patients with double-outlet right ventricle and pulmonary stenosis were operated in our hospital. In present series, the operative mortality rate of former 8 patients was 37.6%, while that of the later 25 cases was 8%. Our experiences in improving the surgical results in double-outlet right ventricle (DORV) are following: (1) A better understanding of DORV pathological anatomy, especially a clear-cut differential diagnosis from tetralogy of Fallot and TGA is mandatory. (2) Strict selection of indications for surgery. (3) Improvement of techniques in perfusion and myocardial protection. (4) Keeping on two principles of surgical treatment: sufficient blood drainage from left ventricle to aorta by using intracardiac tunnel or tube, and adequate relief of the obstruction of right ventricle outflow tract by making RVOT patch or conduit between RV or LV and pulmonary artery. (5) Postoperative care, especially the management postoperative cardiac arrhythmas and low cardiac output syndrome.
