Long term follow-up after isolated aortic valve replacement

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.
