Summary
Prosthetic valve replacement for aortic stenosis is effective, with low operative mortality even in elderly patients. Early intervention improves outcomes, especially for those with advanced disease.
Area of Science:
- Cardiovascular Surgery
- Cardiac Valve Disease
- Geriatric Cardiology
Context:
- Aortic valve stenosis is a significant cause of morbidity and mortality.
- Prosthetic valve replacement has become the standard treatment for symptomatic severe aortic stenosis.
- Outcomes in elderly patients undergoing this procedure require careful evaluation.
Purpose:
- To evaluate the operative mortality and outcomes of prosthetic valve implantation in patients with aortic valve stenosis.
- To assess the impact of age and New York Heart Association (NYHA) functional classification on operative mortality.
- To determine the long-term efficacy of valve replacement in this patient cohort.
Summary:
- Retrospective analysis of 149 patients (mean age 64 years) who underwent prosthetic valve implantation for aortic valve stenosis between 1986 and 1988.
- Overall operative mortality was 3.4%, with a 1-year mortality of 4.7%.
- Higher operative mortality was observed in patients aged 75-86 years (10.3%) compared to younger patients (1.7%). Patients in NYHA grade IV had a 15.8% operative mortality if aged 75-86, versus 4.0% if younger than 75.
Impact:
- Prosthetic valve replacement is the preferred treatment for symptomatic aortic stenosis.
- The procedure demonstrates acceptable mortality rates even in elderly patients.
- Early surgical intervention is crucial for improving outcomes in patients with aortic valve stenosis, particularly the elderly.
