Cohort study reveals long-term survival and reoperation rates after mitral valve replacement, highlighting trade-offs between mechanical and bioprosthetic valves.
Key Points
To compare the 25-year long-term survival, reoperation rates, and valve-related complications in patients undergoing mechanical versus bioprosthetic mitral valve replacement.
Conducted a 25-year province-wide population-based observational cohort study.
Followed patients undergoing primary mitral valve replacement with either mechanical or bioprosthetic valves.
Compared 25-year mortality, reoperation, and major bleeding risks between mechanical and bioprosthetic valve recipients.
Identified critical trade-offs between the durability and bleeding risks of mechanical prostheses versus the structural deterioration and reoperation risks of bioprosthetic valves.
