Summary

Mitral valve reconstruction for endocarditis is feasible and safe, offering excellent functional outcomes. This approach should be strongly considered over valve replacement for mitral insufficiency due to infection.

Area of Science:

  • Cardiology
  • Cardiac Surgery
  • Infectious Diseases

Background:

  • Mitral valve reconstruction offers benefits over replacement for mitral insufficiency.
  • Feasibility and outcomes of reconstruction for endocarditis are not well-established.

Purpose of the Study:

  • To evaluate the feasibility and results of mitral valve reconstruction in patients with mitral insufficiency caused by endocarditis.

Main Methods:

  • Retrospective review of 22 patients undergoing mitral valve reconstruction for endocarditis-related mitral insufficiency.
  • Analysis of preoperative and postoperative echocardiograms, operative findings, and clinical outcomes.
  • Follow-up data including mortality and functional class (New York Heart Association).

Main Results:

Related Experiment Videos

  • 22 patients (mean age 53) underwent reconstruction for isolated mitral valve endocarditis.
  • Preoperative findings included severe mitral insufficiency (20/22) and various valve pathologies.
  • Post-repair, 16 patients had no mitral insufficiency, and 6 had mild insufficiency.
  • No operative or in-hospital deaths; one late death at 30 months.
  • 90% of survivors were in New York Heart Association functional class I or II at follow-up.

Conclusions:

  • Mitral valve reconstruction for active or healed endocarditis is associated with low morbidity and mortality.
  • Excellent functional results were observed in the study cohort.
  • Strong consideration of mitral valve reconstruction over replacement for endocarditis-induced mitral insufficiency is supported.
