Abstract:
Described herein are findings in 55 non-infected bioprostheses that had been in the aortic valve position from 2 to 276 months (mean 107). The major purpose of this study was to illustrate the variable causes prompting excision of the bioprostheses. Fifty-three (96%) patients survived ≥ 30 days following the bioprosthetic excision and 50 (91%) patients lived ≥1 year postoperatively. The techniques used to explant the bioprostheses appear to vary considerably among the operating surgeons.
