Ross procedure

INTRODUCTION: In 1967 Donald Ross introduced the subcoronary Ross procedure consisting of transplantation of the autologous pulmonary valve into aortic position. We describe our 15-year experience in Ross procedures. METHODS: 576 subcoronary operations have been performed (436 male and 140 female patients); the mean age was 45±11.9 years. (range, 13 to 70 years). The mean follow-up was 7±4.2 years (range, 0 to 16 years). There were 4597 patient years at follow-up with a clinical completeness of 95% and echo completeness of 91%. RESULTS: There were two operative deaths (0.3%) and 31 patients with reoperation. The survival is similar to that of the normal population and the freedom from allo- and autograft reoperation is 87% at 15 years. Autograft regurgitation at last examination was grade 0 in 40%, trace in 54%, grade I in 19%, grade II in 4% and grade III in 0.4%; the pressure gradient was smaller than 5 mmHg in 57% and between 5 and 10 mmHg in 24%. Only 6% had a transvalvular pressure gradient of more than 10 mmHg. DISCUSSION: After 15 years of experience it can be concluded that the subcoronary technique provides near normal survival in adult patients, with excellent hemodynamics and acceptable rate of reoperations.
