Usefulness of Global Left Ventricular Longitudinal Strain for Risk Stratification in Low Ejection Fraction, Low-Gradient Aortic Stenosis

Background— The objective of this study was to examine the impact of left ventricular (LV) global longitudinal strain (GLS) measured at rest and at dobutamine stress echocardiography on the outcome of patients with low LV ejection fraction and low-gradient aortic stenosis. Methods and Results— Am…
