Comparison of Magnetic Resonance Imaging and Cardiac Catheterization in Patients with Suspected Severe Aortic Stenosis

Acta Medica, 2008
Objective. Magnetic resonance imaging (MRI) is a novel technique used in the assessment of aortic stenosis. The aim of the study was to compare MRI and cardiac catheterization (CAT) that is still considered to be a “golden standard” in this indication ...

Different patterns of cerebral and muscular tissue oxygenation 10 years after coarctation repair [PDF]

, 2019
The purpose of this study was to assess whether the lower exercise tolerance in children after coarctation repair is associated with alterations in peripheral tissue oxygenation during exercise.

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.

Numerical Modeling of Pulse Wave Propagation in a Stenosed Artery using Two-Way Coupled Fluid Structure Interaction (FSI)

, 2018
As the heart beats, it creates fluctuation in blood pressure leading to a pulse wave that propagates by displacing the arterial wall. These waves travel through the arterial tree and carry information about the medium that they propagate through as well ...

The living aortic valve: From molecules to function. [PDF]

, 2014
The aortic valve lies in a unique hemodynamic environment, one characterized by a range of stresses (shear stress, bending forces, loading forces and strain) that vary in intensity and direction throughout the cardiac cycle.

Echocardiographic evaluation of velocity ratio, velocity time integral ratio, and pulmonary valve area in dogs with pulmonary valve stenosis. [PDF]

, 2018
BackgroundVelocity ratio, velocity time integral (VTI) ratio, and pulmonary valve area indexed to body surface area (iPVA) are methods of assessment of pulmonary valve stenosis (PS) severity that are less dependent on blood flow. Studies evaluating these
