This study shows that mitral valvuloplasty with a rasping procedure is a safe and effective treatment for mitral valve stenosis. It significantly improves heart function and valve area without requiring long-term anticoagulation.

Area of Science:

  • Cardiovascular Surgery
  • Interventional Cardiology
  • Cardiac Surgery

Context:

  • Mitral valve stenosis poses significant risks and requires effective treatment.
  • Traditional surgical approaches can be invasive with potential complications.

Purpose:

  • To evaluate the efficacy and safety of mitral valvuloplasty using a rasping procedure combined with open mitral commissurotomy.
  • To assess short-term and long-term postoperative outcomes.

Summary:

  • Seven patients underwent the combined procedure, showing significant improvements in mitral valve area and reduced transvalvular pressure gradient.
  • Postoperative left ventricular fractional shortening (LVFS) improved, indicating enhanced cardiac function.
  • No restenosis, regurgitation, or infection occurred; one patient experienced late thromboembolism, but no reoperations were needed.

Impact:

  • The rasping procedure offers safe and effective débridement, potentially avoiding long-term anticoagulation.
  • This technique is a viable option for mitral valve stenosis, excluding transmural calcified lesions.
  • Excellent long-term results are anticipated, improving patient quality of life.
