Background: Left ventricular (LV) stroke volume (SV) is ejected by a combination of longitudinal shortening (LS), circumferential shortening (CS) and ventricular twist. Longitudinal shortening is caused by the motion of the mitral annulus towards the apex, causing wall thickening (circumferential and radial shortening), and left ventricular cavity and SV reduction. The role of LS in aortic stenosis (AS) is not defined. Objective: The aim of this study was to analyze the LS and CS contribution to SV and left ventricular ejection fraction (LVEF) in severe AS. Methods: The study included 152 patients (70±12 years, 64 women) with severe AS (valve area |
