Summary

Mitral valve repair is a viable option for patients with bacterial endocarditis, offering low mortality and excellent long-term outcomes. This procedure effectively addresses mitral insufficiency, avoiding reoperation or recurrent infection.

Area of Science:

  • Cardiology
  • Cardiac Surgery
  • Infectious Diseases

Background:

  • Native valve endocarditis frequently leads to mitral insufficiency.
  • Surgical intervention is often necessary to manage the resulting valve dysfunction.

Purpose of the Study:

  • To evaluate the efficacy and safety of mitral valve repair in patients with mitral insufficiency secondary to bacterial endocarditis.
  • To assess long-term outcomes, including mortality, reoperation rates, and valve-related morbidity.

Main Methods:

  • Retrospective analysis of 22 patients who underwent mitral valve repair for endocarditis-related mitral insufficiency.
  • Detailed review of surgical techniques, patient demographics, preoperative and postoperative functional status, and follow-up data.

Main Results:

  • Successful valve repair was achieved in the majority of patients, with significant improvement in New York Heart Association functional class.
  • Low operative mortality (9%) and no late deaths, reoperations, or recurrent endocarditis were observed.
  • Patients experienced no valve-related morbidity or thromboembolic events during a mean follow-up of 24 months.

Conclusions:

  • Mitral valve repair is a safe and effective treatment for mitral insufficiency caused by bacterial endocarditis, applicable in both acute and healed stages.
  • The procedure demonstrates low operative mortality and excellent long-term results, making it an attractive alternative to valve replacement.
