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 …

Low-flow, low-gradient (LF-LG) aortic stenosis (AS) may occur with depressed or preserved
left ventricular ejection fraction (LVEF), and both situations are among the most challenging …

Background: Aortic valve calcification (AVC) load measures lesion severity in aortic stenosis
(AS) and is useful for diagnostic purposes. Whether AVC predicts survival after diagnosis …

Objectives: With concomitant Doppler echocardiography and multidetector computed
tomography (MDCT) measuring aortic valve calcification (AVC) load, this study aimed at …

Objectives: The aim of this case match study was to compare the outcome of patients with
paradoxical low-flow (left ventricular ejection fraction [LVEF]≥ 50% but stroke volume …

Background—Among patients with severe aortic stenosis (AS) and preserved ejection
fraction, those with low gradient (LG) and reduced stroke volume may have an adverse …

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 …

Background: Hemodynamic variables such as cardiac index and right atrial pressure have
consistently been associated with survival in pulmonary arterial hypertension (PAH) at the …

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 …

Objectives: This prospective cohort study in patients with aortic stenosis (AS) aimed to
identify surrogates of myocardial fibrosis that are easy to derive in clinical practice, allow the …
