Summary

Aortic valve replacement surgery offers good long-term outcomes for symptomatic patients, with acceptable early mortality and improved survival rates. Elderly patients experienced less favorable results compared to younger individuals.

Area of Science:

  • Cardiovascular Surgery
  • Cardiac Valve Disease

Background:

  • Aortic valve replacement is a critical intervention for patients with symptomatic aortic valve disease.
  • Understanding the long-term outcomes and operative risks is essential for patient selection and management.

Purpose of the Study:

  • To evaluate the early and late outcomes of isolated aortic valve replacement.
  • To assess the impact of age on the results of aortic valve replacement.

Main Methods:

  • Retrospective review of 102 consecutive patients undergoing isolated aortic valve replacement between January 1982 and June 1989.
  • Analysis of early operative mortality, late mortality, and long-term functional status.
  • Follow-up by cardiologists with a mean duration of 40 months.

Main Results:

  • Overall early operative mortality was 5%, primarily due to pump failure and endocarditis.
  • Younger patients (<70 years) had a 3.5% early mortality, while elderly patients (≥70 years) had an 11% early mortality (P<0.025).
  • Five-year survival was 89%, with 74% of survivors being event-free. Functional improvement was noted in most survivors.

Conclusions:

  • Aortic valve replacement is a viable option for symptomatic patients, associated with acceptable operative mortality.
  • Long-term follow-up demonstrates functional improvement and low mortality rates post-surgery.
  • Age is a significant factor influencing outcomes, with elderly patients facing higher risks.
