Mitral valve reconstruction offers excellent long-term results, with 88% of patients free from recurrent insufficiency 10 years post-operation. Early surgical intervention is recommended for mitral valve prolapse to improve patient outcomes.

Area of Science:

  • Cardiovascular Surgery
  • Cardiac Valve Repair
  • Minimally Invasive Cardiac Surgery

Background:

  • Mitral valve reconstruction has evolved significantly over 18 years.
  • Long-term follow-up data is crucial for assessing surgical technique efficacy.

Purpose of the Study:

  • To summarize outcomes of 1,000 mitral valve reconstructions.
  • To evaluate evolving surgical techniques and approaches for mitral valve repair.

Main Methods:

  • Review of 1,000 patients undergoing mitral valve reconstruction over 18 years.
  • Analysis of Carpentier techniques, including segmental resection with annuloplasty and ring insertion.
  • Evaluation of newer techniques: triangular resection, posterior folding plasty, and minimally invasive approaches (Port-Access).

Main Results:

  • 88% of patients remain free from recurrent mitral insufficiency at 10 years.
  • Reconstruction is feasible in nearly 90% of mitral valve prolapse patients with a ~2% operative mortality.
  • Minimally invasive approach used in 130 patients with positive outcomes.

Conclusions:

  • Mitral valve reconstruction provides durable, long-term benefits.
  • Early surgical intervention is advised for mitral valve prolapse, especially with left ventricular dysfunction or in sinus rhythm.
  • Ongoing evolution of techniques, including minimally invasive options, enhances patient benefits.
