Early Surgery versus Watchful Waiting in Patients with Moderate Aortic Stenosis and Left Ventricular Systolic Dysfunction

BACKGROUND AND OBJECTIVESSevere aortic stenosis (AS) with left ventricular systolic dysfunction (LVSD) is a class I indication for aortic valve replacement (AVR) but this recommendation is not well established in those at the stage of moderate AS. We investigate the clinical impact of AVR among patients with moderate AS and LVSD. METHODSFrom 2001 to 2017, we consecutively identified patients with moderate AS and LVSD, defined as aortic valve area 1.0-1.5 cm² and left ventricular ejection fraction
