Relationship Between Left Ventricular Ejection Fraction and Mortality in Asymptomatic and Minimally Symptomatic Patients With Severe Aortic Stenosis
Objectives This study sought to determine the best left ventricular ejection fraction (LVEF) cutoff value to predict long-term mortality in patients with asymptomatic or minimally symptomatic severe aortic stenosis (AS) and LVEF ≥50% under conservative management and after surgical correction of AS. Background Aortic valve replacement (AVR) is a Class I indication in asymptomatic patients with…
