What are the long-term outcomes and complication rates of bioprosthetic valve replacement in selected patients?
Bioprosthetic valves demonstrate acceptable long-term performance with 83% freedom from valve failure at 8 years, supporting their use in selected patients.
Bloch et al. (1984) studied this question.
