Echocardiography is the key tool for the diagnosis and evaluation of aortic stenosis.
Because clinical decision-making is based on the echocardiographic assessment of its …

LVOT ¼ left ventricular outflow tract MR ¼ mitral regurgitation MS ¼ mitral stenosis MVA ¼
mitral valve area DP ¼ pressure gradient RV ¼ right ventricle RVOT ¼ right ventricular …

After publication, dissemination of the message is of paramount importance. Publication of
executive summaries and the production of pocket-sized and PDA-downloadable versions …

Background—Retrospective studies have suggested that patients with a low transvalvular
gradient in the presence of an aortic valve area< 1.0 cm2 and normal ejection fraction may …

Objectives: We sought to determine to what extent systemic arterial compliance (SAC) might
impact on afterload and left ventricular (LV) function in patients with aortic stenosis (AS) …

Standard echocardiographic evaluation of aortic stenosis (AS) severity includes
measurement of aortic velocity, mean transaortic pressure gradient, and continuity equation …

“Degenerative” or calcific aortic stenosis is a complex, multifaceted, systemic disease that is
not solely limited to the aortic valve but also includes reduced arterial compliance as well as …

Background—We sought to investigate the use of a new parameter, the projected effective
orifice area (EOAproj) at normal transvalvular flow rate (250 mL/s), to better differentiate …

Os principais achados anatomopatológicos da EM consistem no espessamento dos folhetos
valvares, áreas de calcificação, fusão comissural e encurtamento de cordoalhas33 …

Background—Aortic valve area index adjusted for pressure recovery (energy loss index
[ELI]) has been suggested as a more accurate measure of aortic stenosis (AS) severity, but …
