Post-stenotic aortic dilatation. [PDF]

, 2006
Aortic stenosis is the most common valvular heart disease affecting up to 4% of the elderly population. It can be associated with dilatation of the ascending aorta and subsequent dissection.

Significance of Aortic Valve Calcification in Patients With Low‐Gradient Low‐Flow Aortic Stenosis [PDF]

Clinical Cardiology, 2013
AbstractBackgroundAssessment of patients with aortic stenosis (AS) and impaired left ventricular function remains challenging. Aortic valve calcium (AVC) scoring with computed tomography (CT) and fluoroscopy has been proposed as means of diagnosing and predicting outcomes in patients with severe AS.HypothesisSeverity of aortic valve calcification ...

Sigmoid isostiffness-lines: An in-vitro model for the assessment of aortic stenosis severity

Frontiers in Cardiovascular Medicine, 2022
IntroductionThe aortic valve opening area (AVA), used to quantify aortic stenosis severity, depends on the transvalvular flow rate (Q). The currently accepted clinical echocardiographic method assumes a linear relation between AVA and Q.

Haemodynamic Patterns of Severe Aortic Stenosis

Рациональная фармакотерапия в кардиологии, 2020
The authors present up-to-date review of clinical pathophysiology of aortic stenosis (AS) based on differentiation of its haemodynamic patterns, and some actual issues of instrumental diagnostics and classification of AS.

Clinical outcomes of patients with low-flow, low-gradient, severe aortic stenosis and either preserved or reduced ejection fraction undergoing transcatheter aortic valve implantation [PDF]

, 2013
AIMS Our aim was to evaluate the invasive haemodynamic indices of high-risk symptomatic patients presenting with 'paradoxical' low-flow, low-gradient, severe aortic stenosis (AS) (PLF-LG) and low-flow, low-gradient severe AS (LEF-LG) and to compare ...

Subthreshold Aortic Valve Calcium Scores in Severe Aortic Stenosis and Transthyretin Cardiac Amyloidosis

JACC: Case Reports, 2020
We have clinically observed that some patients with transthyretin cardiac amyloidosis and severe aortic stenosis may have lesser degrees of calcification than one might expect.

Assessment of low-flow, low-gradient, severe aortic stenosis: an invasive evaluation is required for decision making.

, 2014
Low-flow, low-gradient severe aortic stenosis (AS) is characterised by a small aortic valve area (AVA) and low mean gradient (MG) secondary to a low cardiac output and may occur in patients with either a preserved or reduced left ventricular ejection ...

High-sensitivity troponin I concentrations are a marker of an advanced hypertrophic response and adverse outcomes in patients with aortic stenosis [PDF]

, 2014
AIMS: High-sensitivity cardiac troponin I (cTnI) assays hold promise in detecting the transition from hypertrophy to heart failure in aortic stenosis.
