Percutaneous balloon mitral commissurotomy offers significant functional improvement for mitral stenosis patients. This minimally invasive procedure is effective for soft valve stenosis but requires careful patient selection.

Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Valvular Heart Disease

Background:

  • Percutaneous balloon mitral commissurotomy (PBMC) introduced in 1984 as an alternative to surgical commissurotomy.
  • PBMC has been widely adopted for treating mitral valve stenosis, improving valvular function.

Purpose of the Study:

  • To evaluate the efficacy and safety of percutaneous balloon mitral commissurotomy.
  • To determine the factors influencing the success of PBMC.
  • To assess the medium-term outcomes of PBMC.

Main Methods:

  • Review of patients undergoing percutaneous balloon mitral commissurotomy.
  • Assessment of pre- and post-procedure valvular function (final area of 2 cm²).
  • Monitoring for complications including mortality, mitral regurgitation, and atrial shunts.

Main Results:

  • PBMC significantly improves valvular function in mitral stenosis.
  • Complication rates are low: 0.5-3% mortality, 5% severe mitral regurgitation.
  • Medium-term results show sustained functional improvement and low restenosis rates in initially successful cases.

Conclusions:

  • PBMC is a safe and effective first-line treatment for soft valve mitral stenosis.
  • Contraindications include left atrial thrombosis and moderate to severe mitral insufficiency.
  • Valve replacement remains the primary treatment for calcified mitral stenosis.
