Reinterventions after percutaneous mitral commissurotomy during long-term follow-up, up to 20 years: the role of repeat percutaneous mitral commissurotomy
Key result
After successful percutaneous mitral commissurotomy, cardiovascular survival without reintervention was 38 ± 2% at 20 years, and survival without surgery was 46 ± 2%.
Why the study?
What is the long-term rate of reintervention and freedom from surgery after successful percutaneous mitral commissurotomy?
Population

Implication
Supports PMC durability in selected mitral stenosis patients; extends observational series but leaves open randomized confirmation of long-term strategy.

Type
Cohort (n=912)
Structured PICO
What is the long-term rate of reintervention and freedom from surgery after successful percutaneous mitral commissurotomy?
P
Population
912 patients with good immediate results after percutaneous mitral commissurotomy, followed for a median of 12 years (up to 20 years).
E
Exposure
Long-term follow-up after successful percutaneous mitral commissurotomy (PMC), including repeat PMC for reintervention.
O
Outcome
Survival without reintervention (surgery or repeat PMC) and survival without surgery alone up to 20 years.hard clinical
After successful percutaneous mitral commissurotomy, almost half of patients remain free from mitral surgery at 20 years, with repeat PMC allowing for further postponement of surgery.
Cite This Study
Bouleti et al. (2013) conducted a cohort in Mitral valve disease post-percutaneous mitral commissurotomy (n=912). Percutaneous mitral commissurotomy (PMC) was evaluated on Cardiovascular survival without reintervention (surgery or repeat PMC). After successful percutaneous mitral commissurotomy, cardiovascular survival without reintervention was 38 ± 2% at 20 years, and survival without surgery was 46 ± 2%.
