Systemic Hypertension in Low Gradient Severe Aortic Stenosis With Preserved Ejection Fraction

Study Questions:

What are the acute hemodynamic effects of afterload-reduction with nitroprusside among patients with low-flow, low-gradient (LF LG) severe aortic stenosis (AS) with preserved left ventricular ejection fraction (LVEF) and incompletely treated systemic hypertension?
