Summary

Elective aortic valve replacement (AVR) is safe for patients over 70, offering improved lifestyles. Emergency surgery and left ventricular failure significantly increase mortality risk in this age group.

Area of Science:

  • Cardiology
  • Cardiac Surgery
  • Geriatric Medicine

Background:

  • Aortic valve replacement (AVR) is a critical procedure for elderly patients with severe aortic valve disease.
  • Assessing risk factors in septuagenarians undergoing AVR is essential for optimizing outcomes.

Purpose of the Study:

  • To identify risk factors associated with aortic valve replacement (AVR) in patients aged 70 and older.
  • To evaluate the safety and efficacy of AVR in the elderly population.

Main Methods:

  • Retrospective review of 35 patients over 70 who underwent AVR.
  • Analysis of patient demographics, procedure types (isolated AVR, double valve, combined AVR and aortocoronary bypass), urgency of operation (elective vs. emergency), and preoperative New York Heart Association (NYHA) functional class.

  • Assessment of hospital mortality, major risk factors, and long-term outcomes.

    • Main Results:

    • Hospital mortality was significantly higher in the emergency group (37.5%) compared to the elective group (7.4%).
    • Urgency of operation and left ventricular failure with severe pulmonary hypertension were identified as major risk factors.
    • No postoperative mortality was observed in patients undergoing combined AVR and aortocoronary bypass procedures.
    • 90% of survivors improved to NYHA Class I or II, indicating enhanced lifestyle.

    Conclusions:

    • Elective aortic valve replacement is a safe and beneficial procedure for septuagenarians.
    • Early AVR intervention is recommended when indicated to mitigate risks associated with emergency surgery and advanced heart failure.
    • Combined AVR and aortocoronary bypass procedures demonstrated a favorable safety profile in this elderly cohort.
