Summary
Percutaneous transvenous mitral commissurotomy (PTMC) offers excellent safety and efficacy for mitral stenosis treatment. While open mitral commissurotomy (OMC) shows greater hemodynamic improvement, PTMC remains a suitable first-line option.
Area of Science:
- Cardiology
- Interventional Cardiology
- Cardiac Surgery
Background:
- Mitral stenosis (MS) is a significant valvular heart disease.
- Percutaneous transvenous mitral commissurotomy (PTMC) and open mitral commissurotomy (OMC) are treatment options for MS.
Purpose of the Study:
- To retrospectively evaluate the effects of PTMC in patients with mitral stenosis.
- To compare the outcomes of PTMC with those of OMC.
Main Methods:
- Retrospective analysis of 34 patients undergoing PTMC.
- Comparison with 28 patients who underwent OMC.
- Evaluation of hemodynamic parameters, mitral valve area, and clinical outcomes (NYHA class).
Main Results:
- PTMC significantly improved transmitral pressure gradient, cardiac index, and mitral valve area (MVA).
- MVA remained increased at follow-up, with no major adverse events.
- OMC demonstrated a greater increase in MVA and NYHA class improvement compared to PTMC.
- PTMC showed significant improvements in NYHA class.
Conclusions:
- OMC offers superior hemodynamic and symptomatic benefits over PTMC.
- PTMC is a safe and effective first-line treatment for mitral stenosis due to its excellent safety profile.
