Abstract
Objective:: Chronic pressure and volume overload may cause different type of left atrial (LA) remodeling in left atrial enlargement (LAE) leading to different cardiovascular outcomes. These two different patterns of LA remodeling can be discriminated by LA eccentricity index (LAEi). The goal of our study was to evaluate an association between LAEi, LV diastolic dysfunction (LVDD), and mitral regurgitation (MR). Method: LAEi was calculated from 3D of left atrium (LA): anteroposterior (D1), superoinferior (D2), mediolateral (D3), and LAEi = D2×2/ (D1+D3). LAE was described as elongated left atrium (EA) if LAEi >= 1.27, and spherical left atrium (SA) if LAEi <1,27.
