Key result
Aortic valve replacement improved ejection fraction at 2 years more in patients with aortic stenosis (56.6% to 71.7%) than in those with aortic insufficiency (54.4% to 61.7%).
Why the study?
Does left ventricular geometric remodeling and ejection fraction improvement differ between patients with aortic stenosis versus aortic insufficiency after aortic valve replacement with a mechanical prosthesis?
Cohort (n=76)
Does left ventricular geometric remodeling and ejection fraction improvement differ between patients with aortic stenosis versus aortic insufficiency after aortic valve replacement with a mechanical prosthesis?
Aortic valve replacement leads to significant left ventricular remodeling and ejection fraction improvement in both aortic stenosis and insufficiency, with greater long-term improvement observed in aortic stenosis patients at 2 years.

EF recovery after mechanical AVR may inform lesion-specific counseling; hypothesis-generating and requires prospective confirmation.
İyem et al. (2007) conducted a cohort in Aortic stenosis and aortic insufficiency (n=76). Aortic valve replacement with a mechanical prosthesis vs. Aortic stenosis vs Aortic insufficiency was evaluated on Left ventricular geometric remodeling, regression of hypertrophy, and ejection fraction. Aortic valve replacement improved ejection fraction at 2 years more in patients with aortic stenosis (56.6% to 71.7%) than in those with aortic insufficiency (54.4% to 61.7%).
