Area of Science:

  • Cardiovascular Surgery
  • Geriatric Cardiology
  • Cardiac Valve Repair

Background:

  • Mitral valve reconstruction in elderly patients with ischemic heart disease is debated due to technical challenges and risks.
  • Potential benefits include preserving left ventricular function and avoiding anticoagulation or reoperations.
  • Elderly patients often have complex cardiac conditions requiring combined procedures.

Purpose of the Study:

  • To evaluate the outcomes of mitral valve reconstruction combined with coronary artery bypass grafting in elderly patients.
  • To assess surgical mortality, morbidity, and long-term functional improvement in this specific patient cohort.

Main Methods:

  • A consecutive series of 100 elderly patients (≥65 years) with severe mitral regurgitation and ischemic heart disease underwent mitral reconstruction and coronary bypass grafting.

Related Experiment Videos

  • Procedures included flexible mitral annuloplasty, with additional complex repairs in 54 patients.
  • Pre- and post-operative New York Heart Association (NYHA) class, ejection fraction, and mitral regurgitation severity were assessed.

    • Main Results:

    • Post-reconstruction, severe mitral regurgitation (4+) was eliminated, with most patients having no or mild (1+) regurgitation.
    • Early mortality was 4% (4 deaths), and late mortality was 6% (6 deaths) at a mean follow-up of 25 months.
    • Significant improvements were observed, with remaining patients achieving NYHA class I or II, indicating enhanced quality of life.

    Conclusions:

    • Coronary bypass grafting and mitral valve reconstruction can be performed safely in elderly patients with ischemic heart disease.
    • The procedure yields acceptable surgical mortality and morbidity, with reliable symptomatic improvement and enhanced quality of life.
    • Longer-term follow-up is necessary, but initial results support the benefit of mitral reconstruction in this population.
