Why the study?
How do long-term outcomes compare among caged-ball, tilting-disc, and porcine biological mitral valve prostheses in patients with isolated mitral disease?
Population
385 patients with isolated mitral disease who received valve prostheses between 1974 and 1981
Design
Cohort
Follow-up
up to 10 years

Porcine bioprostheses were associated with inferior 10-year outcomes; leaves open optimal mitral prosthesis selection pending randomized data.
How do long-term outcomes compare among caged-ball, tilting-disc, and porcine biological mitral valve prostheses in patients with isolated mitral disease?
Long-term follow-up of mitral prostheses demonstrates that porcine bioprostheses have significantly lower freedom from valve-related morbidity and mortality at 10 years compared to mechanical valves, primarily driven by higher valve failure rates.
Vitale et al. (1995) studied this question.
