Prognostic Utility of Left Ventricular Global Longitudinal Strain in Surgery for Primary Mitral Regurgitation: A Systematic Review

Changes in left ventricular global longitudinal strain (LVGLS) have recently been regarded as an early marker of left ventricular (LV) dysfunction in patients with primary mitral regurgitation (MR). We performed a systematic review to study LVGLS as a marker for detection of post-operative outcomes
