Aortic valve replacement surgery significantly improves heart function and reduces symptoms in patients with chronic aortic regurgitation. This procedure offers an acceptable surgical risk with long-term survival benefits.
Area of Science:
- Cardiology
- Cardiac Surgery
- Echocardiography
Context:
- Chronic aortic regurgitation (AR) often leads to left ventricular (LV) systolic dysfunction.
- Aortic valve replacement (AVR) is indicated for symptomatic severe AR, but concerns exist regarding surgical risk in patients with pre-existing LV dysfunction.
Purpose:
- To evaluate the impact of AVR on left ventricular function and clinical status in patients with chronic aortic regurgitation and reduced ejection fraction.
Summary:
- This retrospective study analyzed 40 patients with chronic AR and LV ejection fraction (EF) ≤45%. Preoperative mean EF was 36.2%. After AVR (including 3 Bentall operations), hospital mortality was 7.5%. At a mean follow-up of 69.7 months, surviving patients showed significant improvement in EF (to 55.2%) and reduced LV dimensions.
- Symptomatic improvement was substantial, with severe symptoms decreasing from 60% preoperatively to 6.25% postoperatively. Survival rates at 3, 5, and 7 years were 94%, 91%, and 89%, respectively.
Impact:
- Aortic valve replacement is a safe and effective treatment for chronic aortic regurgitation, even in patients with impaired left ventricular systolic function.
- The procedure leads to significant recovery of left ventricular function, symptomatic relief, and improved long-term survival rates.
