Abstract

Cardiovascular Imaging, Kusunose et al, present an elegant study in which they make
\nthe first proof of concept that preload stress echocardiography
\nperformed with the use of a leg massage machine may successfully increase transvalvular flow rate and therefore differentiate severe from nonsevere AS in patients with LGAS and
\npreserved LVEF.

Stored with the screening record, where it is evidence for the labels above.
