The role of three dimensional transesophageal echocardiography in predicting the effect of cardiac resynchronization therapy on mitral regurgitation in patients with low ejection fraction heart failure
Abstract:Purpose: Cardiac resynchronization therapy (CRT) positively affects the improvement of functional mitral regurgitation (MR) in patients with heart failure with reduced ejection fraction (HFrEF). However, geometric changes in the mitral valve apparatus, subvalvular structures and their contribution to improving mitral regurgitation after CRT have not been clearly defined. Our study aimed to evaluate the geometric parameters of mitral valve apparatus measured with three-dimensional (3D) transesophageal echocardi… Show more
