Low flow state masks true arterial stiffness on pulse wave analysis in patients with severe aortic stenosis
In patients with low gradient aortic stenosis, smaller stroke volume index is associated with lower measured arterial stiffness by augmentation index on pulse wave analysis, suggesting that ventriculo-valvulo-arterial uncoupling due to elevated arterial stiffness may be more pronouncedly under-estimated in patients low-flow, low-gradient aortic stenosis.
