Insights
Percutaneous transarterial balloon dilatation effectively treated mitral stenosis, improving symptoms in 94% of patients. This mitral valve procedure demonstrated acceptable risks and benefits over five years.
Area of Science:
- Cardiovascular Medicine
- Interventional Cardiology
- Valvular Heart Disease
Background:
- Mitral stenosis is a significant cause of morbidity and mortality.
- Transarterial balloon dilatation offers a less invasive treatment option.
Purpose of the Study:
- To evaluate the efficacy and safety of transarterial balloon dilatation for mitral stenosis.
- To assess outcomes up to five years post-procedure.
Main Methods:
- A cohort of 294 patients with mitral stenosis underwent percutaneous transarterial balloon dilatation.
- Functional, hemodynamic, and echocardiographic parameters were analyzed pre- and post-procedure, with long-term follow-up.
Main Results:
- Mean mitral valve area increased by 109%.
- Symptomatic improvement was observed in 94% of patients.
- Complications included death (0.7%), severe mitral insufficiency (2.3%), and cerebral embolism (2%).
Conclusions:
- Transarterial balloon dilatation is an effective treatment for mitral stenosis.
- The procedure offers good results with acceptable morbidity and mortality.
- It presents advantages compared to the anterograde approach.
Objective:
To examine the value of transarterial balloon dilatation of the mitral valve for treatment of patients with mitral stenosis over a period of five years.
Design:
Analysis of patients' functional state, and haemodynamic and echocardiographic variables, before and immediately after the procedure and during a follow up of up to five years.
Setting:
A cardiovascular centre in Belgrade, Yugoslavia.
Patients:
Two hundred and ninety four patients who underwent percutaneous transarterial dilatation of the mitral valve between February 1985 and February 1990.
Results:
Mean mitral valve area was enlarged by 109%. Complications included death (0.7%), severe mitral insufficiency (2.3%), mild mitral insufficiency (9.9%), cerebral embolism (2%), and injury to the femoral artery (2%). Two more patients died at two and 11 months after the procedure. Late cardiac surgery was needed in eight patients (mitral insufficiency in three, restenosis in three, thrombus in one, and endocarditis in one. Restenosis occurred in seven patients. Four of these underwent repeat dilatation and three had surgery. Improvement of symptoms was seen in 94% of patients during the follow up.
Conclusion:
Transarterial balloon dilatation of the mitral valve gave good results with acceptable morbidity and mortality and had some advantages over the anterograde approach.
