Percutaneous mitral balloon valvotomy for patients with mitral stenosis
Key result
Echo score ≤8 is linked to ~35% higher absolute 80-month survival after percutaneous mitral balloon valvotomy.
- P<0.0001
Why the study?
The immediate and long-term outcomes of percutaneous mitral balloon valvotomy in patients with mitral stenosis, stratified by echocardiographic score, were not fully characterized.
Does echocardiographic score predict long-term outcomes in patients with mitral stenosis undergoing percutaneous mitral balloon valvotomy?
Population
Patients with mitral stenosis undergoing percutaneous mitral balloon valvotomy
Comparison
Patients with echocardiographic scores of 8 or less vs greater than 8
Design
Observational cohort study
Follow-up
80 months

Implication
Echocardiographic score may aid prognostication after mitral valvotomy; leaves open its role in patient selection pending prospective validation.

Main Result
Absolute Event Rate: 83% vs 48%

Percutaneous mitral balloon valvotomy provides excellent long-term outcomes and may be the treatment of choice for patients with mitral stenosis and an echocardiographic score of 8 or less.

Igor F. Palacios (1994) conducted an observational in Mitral stenosis. Echocardiographic score ≤ 8 vs. Echocardiographic score > 8 was evaluated on Survival at 80-month follow-up (p=< 0.0001). In patients undergoing percutaneous mitral balloon valvotomy, an echocardiographic score ≤8 was associated with higher 80-month survival compared to scores >8 (83% vs 48%, P<0.0001).
