An important proportion of patients with aortic stenosis (AS) have a 'low-gradient'AS, ie a
small aortic valve area (AVA< 1.0 cm2) consistent with severe AS but a low mean …

Transcatheter aortic valve implantation (TAVI) has spawned the evolution of novel catheter-
based therapies for a variety of cardiovascular conditions. Newer device iterations are …

Up to 40% of patients with aortic stenosis (AS) harbor discordant Doppler-
echocardiographic findings, the most common of which is the presence of a small aortic …

Background: Low mean transvalvular gradient (< 40 mm Hg) and small aortic valve area (<
1.0 cm2) in patients with aortic stenosis (AS) and preserved left ventricular ejection fraction …

Transcatheter aortic valve replacement (TAVR) is a transformative innovation that provides
treatment for high or prohibitive surgical risk patients with symptomatic severe aortic stenosis …

The “Guidelines for the clinical indications of echocardiography” of the Japanese Circulation
Society (JCS) were first developed between 1993 and 1994, and the first revision1 was …

Background: Systemic arterial load impacts the symptomatic status and outcome of patients
with calcific degenerative aortic stenosis (AS). However, assessing vascular properties is …

Background: In patients with aortic stenosis undergoing transcatheter aortic valve
replacement (TAVR), studies have suggested that reduced left ventricular (LV) ejection …

Aims: The study analyses the outcome of patients undergoing transcatheter aortic valve
implantation (TAVI) for different subtypes of severe aortic stenosis (AS) based on data from …

Background: Low flow (LF) can occur with reduced (classic) or preserved (paradoxical) left
ventricular ejection fraction (LVEF). Objectives: The objective of this study was to compare …
