Summary
Percutaneous mitral commissurotomy is a feasible procedure for adults with mitral stenosis. This minimally invasive technique significantly improves valve function with a low complication rate.
Area of Science:
- Cardiology
- Interventional Cardiology
- Cardiac Surgery
Background:
- Mitral stenosis is a significant valvular heart disease.
- Percutaneous mitral commissurotomy offers a less invasive treatment option.
Purpose of the Study:
- To evaluate the feasibility and outcomes of percutaneous mitral commissurotomy in adult patients with mitral stenosis.
Main Methods:
- Twenty-six adult patients with mitral stenosis underwent percutaneous mitral commissurotomy.
- A single or double balloon technique (Trefoil) was employed for valvuloplasty.
Main Results:
- The procedure was successful in 20 patients (77%), with significant improvements observed.
- Mean transvalvular gradient decreased from 14 ± 4 mm Hg to 7 ± 2 mm Hg (P < 0.001).
- Mean valve area increased from 1.1 ± 0.2 cm² to 2.2 ± 0.4 cm² (P < 0.01).
- One patient experienced hemopericardium; five procedures failed. One patient with severe disease had increased mitral regurgitation.
Conclusions:
- Percutaneous mitral commissurotomy is a feasible and effective treatment for adult mitral stenosis.
- The procedure leads to significant hemodynamic improvement with a low complication rate.
