Summary

Mitral valve repair outcomes show increased risk in patients over 65, but this group faces higher risks with valve replacement surgery. Further research is needed for this demographic.

Area of Science:

  • Cardiovascular Surgery
  • Geriatric Cardiology

Background:

  • Mitral valve reconstruction techniques are established, but data primarily focuses on younger patients (<65 years).
  • The safety and efficacy of mitral valve repair in elderly populations remain less understood.

Purpose of the Study:

  • To evaluate the outcomes of mitral valve reconstruction in a mixed-age population, with a specific focus on elderly patients (≥65 years).
  • To compare the hospital mortality rates between younger and older patient groups undergoing mitral valve repair.

Main Methods:

  • A retrospective analysis of 176 patients who underwent mitral valve reconstruction between April 1985 and September 1988.
  • Patients were categorized by age ( <65 years vs. ≥65 years) and compared for hospital mortality.
  • Carpentier's classification and technique were utilized for all repairs.

Main Results:

  • The study included 176 patients with a mean age of 63 years; 52% were aged 65 or older.
  • Hospital mortality was 4% in patients <65 years and 12% in patients ≥65 years.
  • Overall hospital mortality was 8.5%, with higher rates observed in the elderly group.

Conclusions:

  • Mitral valve repair in patients aged 65 years and older is associated with increased hospital mortality compared to younger patients.
  • Despite increased morbidity, mitral valve repair may still offer a lower risk profile for elderly patients compared to mitral valve replacement.
  • Further investigation into optimizing mitral valve repair strategies for geriatric populations is warranted.
