Analysis of echocardiographic parameters for the evaluation of Aortic Regurgitation

In the present study different approaches for the evaluation of aortic regurgitation (AR) in patients with chronic AR and in patient after TAVI were analysed. 55 patients with chronic AR and 15 patients with AR after TAVI were analysed by the conventional approach, semi-quantitative parameters and global left ventricular (LV) peak systolic strain (PSS). The conventional approach was performed by the assessment of the regurgitant fraction (RF), the regurgitant volume (RV), the effective and total stroke volume (SV). In TAVI patients AR was additionally analysed by the proportion of the valvular defect to the aort…
