Mitral valve replacement with ball valve prostheses
Why the study?
What are the mortality and thromboembolic complication rates following mitral valve replacement with different models of ball valve prostheses?
Population
Patients undergoing isolated or multiple mitral valve replacement with ball valve prostheses over a decade.
Design
Cohort
Follow-up
Up to a decade

Implication
May support cloth-covered designs for lower thromboembolism risk; extends early prosthesis data but warrants modern validation.
Structured PICO
What are the mortality and thromboembolic complication rates following mitral valve replacement with different models of ball valve prostheses?
P
Population
Patients undergoing isolated or multiple mitral valve replacement with ball valve prostheses over a decade.
I
Intervention
Mitral valve replacement with ball valve prostheses (including earliest models, Model 6120, and totally cloth-covered Model 6310)
O
Outcome
Operative mortality, late mortality, and thromboembolic complicationshard clinical
Improvements in ball valve prosthesis design, particularly the development of totally cloth-covered models, significantly reduced the incidence of thromboembolic complications after mitral valve replacement.
