Mitral valve re-repair is a feasible surgical option for failed repairs, offering good outcomes. However, reoperative surgery increases risks, necessitating careful consideration of technical aspects and patient selection for successful mitral valve repair.

Area of Science:

  • Cardiovascular Surgery
  • Cardiac Valve Repair
  • Reoperative Cardiac Surgery

Background:

  • 1,596 mitral valve repairs were performed between 1998 and 2004.
  • 23 of these cases involved re-repair of previously repaired mitral valves.

Purpose of the Study:

  • To analyze the causes of mitral valve repair failure.
  • To evaluate technical considerations for mitral valve re-repair.
  • To assess the outcomes of mitral valve re-repair.

Main Methods:

  • Retrospective analysis of 23 mitral valve re-repair cases.
  • Identification of etiologies for failed primary repairs.
  • Review of technical strategies and patient outcomes.

Main Results:

  • Myxomatous valve disease was the primary indication for initial repair in 14 patients.
  • Repair failure causes included early recurrence (infective endocarditis, technical issues) and late recurrence (annular dilatation).
  • 13 of 16 surviving patients were free from mitral regurgitation at follow-up; two required subsequent mitral valve replacement.

Conclusions:

  • Mitral valve re-repair is technically feasible and can yield good functional results.
  • Reoperative mitral valve surgery is associated with increased postoperative morbidity and mortality.
  • Careful surgical planning is crucial for successful mitral valve re-repair outcomes.
