Background: Few data exist on patients with low-flow, low-gradient aortic stenosis (LFLG-
AS) undergoing transcatheter aortic valve replacement (TAVR). Also, very scarce data exist …

Aortic valve stenosis (AS) is no longer considered to be a disease of fixed left ventricular
(LV) afterload (due to an obstructive valve), but rather, functions as a series circuit with …

Background The aging population has led to an increasing number of older patients
undergoing cardiac surgeries/procedures. Frailty and prefrailty have emerged as important …

Background The prognostic implications of discordant grading in severe aortic stenosis (AS)
are well known. However, the prevalence of different flow-gradient patterns and their …

Objectives The aim of this study was to assess the impact of aortic valve replacement (AVR)
on survival in patients with each subclass of low-gradient (LG) aortic stenosis (AS) and to …

Background Patients with symptomatic severe aortic stenosis and a history of chest radiation
therapy represent a complex and challenging cohort. It is unknown how transcatheter aortic …

Background Many patients with severe aortic stenosis (AS) and an indication for aortic valve
replacement (AVR) do not undergo treatment. The reasons for this have not been well …

Objectives This study determined whether flow state classified by stroke volume index (SVi)
or transvalvular flow rate (FR) improved risk stratification of all-cause mortality …

Background: Although aortic valve replacement (AVR) can be lifesaving, many patients with
symptomatic aortic stenosis do not undergo appropriate therapy. This study sought to …

Background: Few data exist on the comparative long-term outcomes of severe aortic
stenosis (AS) patients with different flow-gradient patterns undergoing transcatheter aortic …
