Role of Speckle Tracking Echocardiography to Predict Left Ventricular Dysfunction Post Mitral Valve Replacement Surgery for Severe Mitral Regurgitation.

Background: Despite improvement in the surgical procedure and strictly following the guidelines for mitral valve replacement (MVR), left ventricular dysfunction still occurs. Novel echocardiographic indices can predict development of LV (left ventricle) dysfunction post MVR. LV-GLS (global longitudinal strain) derived from speckle tracking echocardiography, has been proposed as a novel measure to better depict latent LV dysfunction.
