The central double-orifice technique effectively treats complex mitral valve regurgitation, showing high survival and low reoperation rates in a 7-year study of 260 patients.

Area of Science:

  • Cardiovascular Surgery
  • Cardiac Valve Repair
  • Mitral Valve Disease

Background:

  • Complex mitral valve lesions present significant challenges in surgical repair.
  • Mitral regurgitation mechanisms vary, including leaflet prolapse and annular issues.
  • Degenerative disease is the most common cause of mitral regurgitation.

Purpose of the Study:

  • To evaluate the effectiveness and durability of the central double-orifice technique for complex mitral valve repair.
  • To assess outcomes in a large patient cohort undergoing this specific surgical approach.

Main Methods:

  • The central double-orifice repair was performed on 260 patients over 7 years.
  • Patient data included age, mechanism of mitral regurgitation, and etiology.
  • Follow-up assessed survival and reoperation rates.

Main Results:

  • Hospital mortality was low at 0.7%.
  • Five-year overall survival reached 94.4%.
  • Five-year freedom from reoperation was 90.0%, though lower in rheumatic disease patients without annuloplasty.

Conclusions:

  • The central double-orifice technique demonstrates effectiveness and durability for mitral valve reconstruction.
  • This technique is a valuable addition to the surgical options for complex mitral valve lesions.
