Impact of low stroke volume on mortality in patients with severe aortic stenosis and preserved left ventricular ejection fraction
ConclusionLow flow defined as SVi < 30 mL/m2 or SV < 55 mL is an important outcome predictor in severe AS with preserved LVEF under medical and surgical management. Further studies are needed to prospectively test these values for risk stratification and decision making.
