Mitral valve prolapse is a leading cause of mitral regurgitation surgery. Mitral valvuloplasty is effective and safe, offering good long-term outcomes for patients with prolapse.

Area of Science:

  • Cardiology
  • Cardiac Surgery
  • Valvular Heart Disease

Background:

  • Mitral valve prolapse (MVP) is a frequent reason for mitral valve surgery.
  • Understanding the etiologies and outcomes of mitral regurgitation surgery is crucial.

Purpose of the Study:

  • To determine the prevalence of mitral prolapse as an etiology for mitral regurgitation surgery.
  • To evaluate the applicability and outcomes of mitral valvuloplasty in patients with mitral prolapse.

Main Methods:

  • Retrospective analysis of 457 patients undergoing surgery for pure mitral regurgitation between 1985-1987.
  • Categorization of etiologies including mitral prolapse, rheumatic valvulitis, ischemic disease, and bacterial endocarditis.
  • Assessment of valvuloplasty techniques and reconstructive procedures in patients with mitral prolapse.

Main Results:

  • Mitral prolapse was the most common etiology (67%) among patients requiring mitral regurgitation surgery.
  • Chordal rupture was the primary anatomic disturbance in MVP patients (62%).
  • Valvuloplasty was performed in 64% of all patients and 68% of MVP patients, with a 4% operative mortality in the valvuloplasty group.

Conclusions:

  • Mitral prolapse is the predominant cause of mitral regurgitation requiring surgical intervention.
  • Mitral valvuloplasty is a viable and safe option for the majority of patients with mitral prolapse.
  • Valvuloplasty demonstrates low operative mortality and favorable long-term clinical outcomes, including low reoperation and thromboembolic event rates.
