Clinical significance of myocardial contraction fraction in significant primary mitral regurgitation
Archives of Cardiovascular Diseases（2023）
Abstract
•MCF can easily be obtained by Doppler echocardiography.•MCF measures LV myocardial shortening independently of size or geometry.•Reduced MCF is linked to poor outcome in primary MR.•MCF refines current risk stratification in significant primary MR.
