Abstract: Left ventricular (LV) ejection fraction (EF)is the most commonly used measure of LV function. It is used in the risk stratification of patients with aortic stenosis. Recent studies indicate the prognosis of moderate AS with systolic dysfunction is poor. This underscores the importance of detecting mild degree of LV systolic dysfunction in patients with moderate AS.LV global longitudinal strain (GLS) is a more sensitive marker for LV systolic function than LVEF and provides more prognostic information than LVEF in patients with moderate aortic stenosis.
