Key result
Bioprosthetic valves show similar survival to mechanical valves in dialysis patients, with fewer bleeding events.
Why the study?
There is controversy regarding the choice of prosthetic valves in patients with cardiac valve disease who are dialysis-dependent.
Does bioprosthesis valve replacement improve survival and reduce valve-related morbidity compared to mechanical valve replacement in dialysis-dependent patients?
Population
73 consecutive dialysis patients undergoing cardiac valve replacement in China
Comparison
Bioprosthesis valves vs mechanical valves
Design
Retrospective cohort study
Follow-up
Mean 47 ± 23 months

May support bioprosthetic valves in dialysis patients to reduce events; leaves open need for randomized confirmation.

Does bioprosthesis valve replacement improve survival and reduce valve-related morbidity compared to mechanical valve replacement in dialysis-dependent patients?
Absolute Event Rate: 5.3% vs 5.7%
p-value: p=NS
Bioprosthetic valves offer similar survival but significantly lower rates of thromboembolic and bleeding events compared to mechanical valves in dialysis-dependent patients.
Chen et al. (2013) conducted a cohort in Cardiac valve disease in dialysis-dependent patients (n=73). Bioprosthetic valve replacement vs. Mechanical valve replacement was evaluated on Hospital mortality (p=NS). Bioprosthetic valve replacement in dialysis-dependent patients demonstrated similar hospital mortality and late survival compared to mechanical valves, while significantly improving freedom from thromboembolic and bleeding events.
