Follow-up of patients undergoing percutaneous mitral balloon valvotomy. Analysis of factors determining restenosis.
Why the study?
Does echocardiographic score predict clinical and hemodynamic outcomes after percutaneous mitral balloon valvotomy?
Population
100 consecutive patients undergoing percutaneous mitral balloon valvotomy, divided by echocardiographic score.

Implication
Supports echo score for PMV candidate selection; leaves open randomized outcome validation.
Structured PICO
Does echocardiographic score predict clinical and hemodynamic outcomes after percutaneous mitral balloon valvotomy?
P
Population
100 consecutive patients undergoing percutaneous mitral balloon valvotomy (PMV), divided by echocardiographic score (≤8 [n=57] vs >8 [n=43]).
I
Intervention
Percutaneous mitral balloon valvotomy (PMV)
O
Outcome
Clinical outcomes (NYHA functional class, death, need for mitral valve replacement) and restenosis at 13 +/- 1 months follow-up
Percutaneous mitral balloon valvotomy provides excellent clinical and hemodynamic results with low restenosis rates in patients with an echocardiographic score of 8 or less, whereas outcomes are significantly worse in those with higher scores.
