New Findings Reshape Watchful Waiting for Asymptomatic Sever
For patients with severe primary mitral regurgitation (MR), left ventricular global longitudinal strain (LV-GLS) is a robust and significant predictor of long-term outcome that goes beyond the utility of established prognostic measures. Moreover, LV-GLS yields its prognostic value well before LV ejection fraction and LV dimensions meet guideline-defined thresholds for intervention. So finds a large, long-term observational study of Cleveland Clinic patients with asymptomatic severe primary MR recently published in Journal of the American College of Cardiology (JACC)....
