Survival by stroke volume index in patients with low-gradient normal EF severe aortic stenosis

Survival by stroke volume index in patients with low-gradient normal EF severe aortic stenosis

Objective Low-gradient (LG) severe aortic stenosis (AS) and preserved EF with reduced stroke volume are associated with an adverse prognosis, but the relationship of stroke volume index (SVI) with mortality among a range of values is unknown. We investigated the prognostic impact of SVI in this popu...

Zusammenfassung:Objective Low-gradient (LG) severe aortic stenosis (AS) and preserved EF with reduced stroke volume are associated with an adverse prognosis, but the relationship of stroke volume index (SVI) with mortality among a range of values is unknown. We investigated the prognostic impact of SVI in this population. Methods We examined 405 consecutive patients with preserved EF (≥50%) and severe AS (valve area
