Abstract

A retrospective long-term evaluation of the St. Jude Toronto stentless bioprosthesis in patients aged 60 years or younger. From 1994 to 1997, 50 patients underwent aortic valve replacement with the prosthesis. Patients mean age at surgery was 54.5±6.3 years. Follow-up data were acquired by patient file research and telephone interviews. Morbidity and mortality were evaluated with time-to-event analyses using the Kaplan-Meier-method. The log-rank test was used to determine influencing factors for long-term survival and reoperation. Mean follow-up was 13.5±6.3 years with a total follow-up of 661.8 patient-years and a maximum of 20.0 years. Follow-up was 97.8% complete. Associated procedures were performed in 12 patients (24%), including coronary artery bypass grafting, mitral valve replacement and replacement of the ascending aorta. Freedom from reoperation at 10 and 15 years was 76.0±6.7% and 44.1±8.9%, respectively. Reoperations (n=26) started 4.4 years after implantation and were necessary due to: valve degeneration with regurgitation in 79.2% and stenosis in 12.5%, endocarditis in 4.2% and sinus valsalva aneurysm in 4.2% of the cases. The log-rank test revealed that only body-mass-index>25 lowered freedom-from-reoperation,...Continue Reading
