Effect of valve deformity on results and mitral regurgitation after Inoue balloon commissurotomy.
Why the study?
Do age and extent of valve deformity affect the acute results of PTMC using the Inoue balloon in patients undergoing mitral commissurotomy?
Population
162 patients undergoing percutaneous transvenous mitral commissurotomy (PTMC), mean age 52 +/- 14 years.
Comparison

Implication
Supports Inoue balloon PTMC irrespective of age or deformity; leaves open need for prospective outcome validation.
Structured PICO

I
Intervention
Percutaneous transvenous mitral commissurotomy (PTMC) with the Inoue balloon
C
Comparator
Subgroups compared based on echocardiographic score (≤8 vs >8) and age (<60 vs ≥60 years, <70 vs ≥70 years)
O
Outcome
Increase in mitral valve area and mitral regurgitation acutely after the proceduresurrogate
Age and extent of valve deformity do not significantly affect the acute results of PTMC using the Inoue balloon, likely due to its unique geometry and controlled sizing.
