EDLLCW-UP STUDIES OF VALVE REPLACEMENP WITH THE SAINT JUDE MEDICAL VALVE PROSTHESIS

Abstract

From January 1980 to April 1990, 122 patients underwent aortic and/or mitral value replacement with the St. Jude Medical valve prosthesis. Early mortality was 10.7% overall and 23.1% after aortic, 8.0% after mitral and 4.8% after double valve replacement. The total follow-up was 425 patient-years(follow up rate 99.2%).
The 8-year suvival excluding early death was 81%±13% after aortic, 93%±3% after mitral, 63%±26% after double valve replacement. The overall incidences of thranboembolsim, anticoagulant-related hemorrhage and paravalvular leak during follow-up period were 0.71%, 0.24%, and 0.24%/patient-year, resoectively. There have been no instances of primary structural deterioration or prosthetic valve endocarditis.
These results clarify that the St. Jude Medical valve prosthesis is excellent alternative of aortic and mitral position.
