Abstract

OBJECTIVES: In this individual participant data meta-analysis on left ventricular global longitudinal strain (LVGLS), our objective was to: 1) describe its distribution; 2) identify the most predictive cutoff values; and 3) assess its impact on mortality in asymptomatic patients with significant aortic stenosis (AS) and preserved left ventricular ejection fraction (LVEF). BACKGROUND: The evidence supporting the prognostic role of LVGLS in asymptomatic patients with AS has been obtained from several relatively small studies. METHODS: A literature search was performed for studies published between 2005 and 2017 without language restriction according to the following criteria: "aortic stenosis"..
