Long-term outcomes of valve replacement with modern prostheses in young adults
Key result
Valve replacement in young adults resulted in 15-year survival rates of 80.1% after AVR and 71.5% after MVR, with equivalent late survival between bioprosthetic and mechanical valves.
Why the study?
Does bioprosthetic valve replacement improve survival, functional status, and quality of life compared to mechanical valve replacement in young adults (age 18-50) undergoing AVR or MVR?

Implication
Equivalent survival supports individualized bioprosthetic choice in young adults for potential functional gains; leaves open causal confirmation by randomized trials.

In young adults undergoing valve replacement, bioprostheses offer equivalent long-term survival to mechanical valves but are associated with better physical capacity and lower disability, particularly in the aortic position.
Cite This Study
Ruel et al. (2004) conducted a cohort in Aortic and/or mitral valve disease requiring replacement (n=500). Valve replacement with contemporary prostheses vs. Mechanical vs bioprosthetic valves was evaluated on Survival, events, functional status, and quality of life. Valve replacement in young adults resulted in 15-year survival rates of 80.1% after AVR and 71.5% after MVR, with equivalent late survival between bioprosthetic and mechanical valves.
