We report here our experience with SPV used in the Ross procedure. METHODS: Between March 1992 and February 2011, 360 patients had a Ross procedure; 61 patients received a SPV in pulmonary position and they represent the study population. Mean age was 38 ± 7.6 years. Indication for surgery was an infective endocarditis in 15 cases, there were 3 redo operations. Median SPV diameter was 29 mm (range, 25 to 29 mm). Pulmonary stenosis was defined as a peak transvalvular gradient of more than 50 mm Hg. RESULTS: Perioperative mortality was 4.9% (3 patients) and late mortality was 3.3% (2 patients). Median follow-up was 4 years (range, 7 days to 14.9 years). There was no reoperation on the right ventricle outflow tract, and freedom from pulmonary stenosis was 100% at 5 years. Mean transpulmonary gradients were 7.1 ± 3.1 mm Hg and 13.5 ± 6.8 mm Hg postoperatively and at 5 years, respectively. Mean transpulmonary gradient increased faster over time when the SPV diameter was less than 29 mm (p = 0.03). CONCLUSIONS: The SPV could represent an alternative to cryopreserved pulmonary homografts during the Ross procedure in adult patients. Hemodynamic results were improved by using large diameter SPV, but longer follow-up is mandatory to confirm those results.Lire moins >
