Summary

Percutaneous mitral valvuloplasty (PMV) significantly improved heart function in patients with mitral stenosis. Both single- and double-balloon techniques effectively reduced pressure gradients and increased cardiac output.

Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Cardiac Surgery

Background:

  • Mitral stenosis (MS) is a significant valvular heart disease.
  • Percutaneous mitral valvuloplasty (PMV) offers a less invasive treatment option.
  • Evaluating the efficacy of PMV using different balloon techniques is crucial.

Purpose of the Study:

  • To assess the outcomes of percutaneous mitral valvuloplasty (PMV) in patients with mitral stenosis.
  • To compare the effectiveness of single-balloon versus double-balloon techniques for PMV.
  • To evaluate hemodynamic changes post-PMV.

Main Methods:

  • A study involving 57 patients with mitral stenosis undergoing PMV.
  • Utilized single-balloon (trefoil or bifoil) in 49 patients and double-balloon (trefoil + monofoil) in 8 patients.

  • Cardiac catheterization was performed before and after a 3-month follow-up period.

    • Main Results:

    • Both single- and double-balloon PMV significantly reduced mitral valve gradient, left atrial pressure, and pulmonary pressures.
    • Mitral valve area and cardiac output significantly increased in both groups post-procedure.
    • Statistically significant improvements (p < 0.001) were observed for all measured hemodynamic parameters.

    Conclusions:

    • Percutaneous mitral valvuloplasty (PMV) is an effective treatment for mitral stenosis.
    • Both single- and double-balloon techniques yield significant hemodynamic improvements.
    • PMV leads to substantial relief of mitral stenosis symptoms and improved cardiac function.
