Combined Circumferential and Longitudinal Left Ventricular Systolic Dysfunction in Patients with Asymptomatic Aortic Stenosis

摘要

BackgroundEarly detection of left ventricular (LV) systolic dysfunction is pivotal in the management of patients with aortic stenosis (AS). LV circumferential and/or longitudinal shortening may be impaired in these patients despite LV ejection fraction is preserved. We focused on prevalence and factors associated with combined impairment of circumferential and longitudinal shortening (C&L) in asymptomatic AS patients.
