Percutaneous balloon mitral valvotomy offers a less invasive way to treat mitral stenosis. Ideal candidates, often younger patients with specific echocardiographic scores, experience good outcomes, but many others also benefit.

Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Cardiac Surgery

Background:

  • Mitral stenosis is a significant valvular heart disease.
  • Percutaneous balloon mitral valvotomy (PMV) offers an alternative to surgical intervention.
  • Understanding patient selection and outcomes is crucial for effective treatment.

Purpose of the Study:

  • To evaluate the efficacy and safety of percutaneous balloon mitral valvotomy.
  • To identify optimal candidates for PMV.
  • To assess the long-term outcomes and complications associated with PMV.

Main Methods:

  • Transseptal catheterization for antegrade balloon placement.
  • Echocardiography for patient selection and scoring (≤8).
  • Exclusion criteria included atrial fibrillation, mitral regurgitation, valvular calcification, and prior surgery.

Main Results:

  • Good immediate and midterm results observed in most patients.
  • 2-year survival free from mitral valve replacement is 84%.
  • Low procedural mortality and morbidity in experienced centers.

Conclusions:

  • PMV is an effective treatment for mitral stenosis, particularly in carefully selected younger patients.
  • Echocardiography plays a vital role in patient selection for PMV.
  • While ideal candidates exist, many non-ideal candidates also achieve substantial relief.
