Summary
Mitral balloon valvulotomy (MBV) offers long-term success for mitral stenosis patients. Sinus rhythm and absence of calcium predict better outcomes.
Area of Science:
- Cardiology
- Interventional Cardiology
Background:
- Mitral balloon valvulotomy (MBV) is effective for mitral stenosis.
- Long-term outcomes and predictors of success after MBV require further investigation.
Purpose of the Study:
- To analyze long-term follow-up data for patients treated with MBV.
- To identify factors influencing late success after MBV.
Main Methods:
- Analysis of 350 patients with mitral stenosis treated by MBV.
- Clinical follow-up ranging from 6 months to 6 years.
- Echocardiographic and hemodynamic reevaluations.
Main Results:
- 84% of patients remained in functional class I-II after a mean follow-up of 38 months.
- 5-year survival rate was 94%.
- Sinus rhythm and absence of calcium on fluoroscopy were independent predictors of late success.
Conclusions:
- MBV provides durable long-term benefits for selected mitral stenosis patients.
- Maintaining sinus rhythm and avoiding valve calcification are crucial for sustained success.
