Does aortic valve replacement improve survival and ventricular recovery in patients with aortic valve disease and left ventricular dysfunction?
Does aortic valve replacement improve survival and ventricular recovery in patients with aortic valve disease and left ventricular dysfunction?
Aortic valve replacement in patients with aortic valve disease and LV dysfunction yields excellent long-term survival and should not be denied based on low ejection fraction alone.
Objective: The aim of the study was to assess the effects of aortic valve replacement (AVR) in patients with aortic stenosis (AS) or regurgitation (AR) and left ventricular (LV) dysfunction. Patients and methods: Retrospective analysis identified 75 consecutive patients with left ventricular ejection fraction (LVEF) assessed by echocardiography 10.9% in the AS and AR groups after echocardiography control. The survival rates at 1, 5 and 10 years were respectively 94.4%, 87% and 80% in AS group and 95.2%, 93% and 89% in AR group. Conclusion: Despite higher perioperative mortality in patients with aortic valve disease (AS or AR) and LV dysfunction, long-term outcome is excellent. We, therefore, conclude that AVR can be performed and it should not be denied to patients on the basis of low EF alone.
