Abstract:

Background: Left ventricular dysfunction remains a major prognostic indicator of the outcome of patients undergoing surgery for aortic valve stenosis (AS). These groups of patients are heterogeneous; they include patients with low and high transvalvular gradient. The aim of this study was to compare the results of aortic valve replacement (AVR) for AS and severe left ventricular (LV) systolic dysfunction in patients with low and high transvalvular gradient and to identify whether the transvalvular gradient has a determinant value in these results. Methods: In this retrospective bicentric study, 61 patients who underwent isolated AVR for severe AS associated to reduced LV function (LVEF < 40%) were enrolled. The patients were divided into two groups according to the mean transvalvular gradient: Group 1 with mean gradient

Keywords: Severe aortic stenosis, Aortic valve replacement, Low transvalvular gradient, Left ventricular dysfunction, Left ventricular function recovery.
