Summary

Aortic valve replacement in octogenarians (≥80 years) showed higher early mortality but comparable clinical improvement and hospital resource use versus younger patients (65-75 years). This study provides data on outcomes for elderly patients undergoing this procedure.

Area of Science:

  • Cardiology
  • Cardiac Surgery
  • Geriatric Medicine

Background:

  • Aortic valve replacement (AVR) in octogenarians may be more complex and resource-intensive.
  • Limited data exist on the outcomes of AVR in patients aged 80 years and older.

Purpose of the Study:

  • To compare the outcomes of AVR in patients aged 80 years and older with those in patients aged 65 to 75 years.
  • To evaluate resource utilization and clinical improvement in elderly AVR patients.

Main Methods:

  • Retrospective analysis of 44 patients (≥80 years) and 83 matched controls (65-75 years) who underwent AVR.
  • Data collected from hospital records and telephone interviews.
  • Preoperative functional status (New York Heart Association class) was assessed.

Main Results:

  • Older patients had higher early mortality (14% vs 4%) and postoperative low cardiac output syndrome (p=0.049).
  • No significant differences in respirator support, ICU stay, or total hospital stay.
  • Similar late valve-related complications and comparable 2-year survival rates (73% vs 90%).

Conclusions:

  • Despite poorer preoperative status, AVR in octogenarians did not increase hospital resource use.
  • Clinical improvement in octogenarians was comparable to younger patients.
  • AVR is a viable option for selected elderly patients, offering significant functional benefits.
