Structure‐based finite strain modelling of the human left ventricle in diastole [PDF]
International Journal for Numerical Methods in Biomedical Engineering, 2013 Finite strain analyses of the left ventricle provide important information on heart function and have the potential to provide insights into the biomechanics of myocardial contractility in health and disease. Systolic dysfunction is the most common cause

A modified Holzapfel-Ogden law for a residually stressed finite strain model of the human left ventricle in diastole [PDF]
Biomechanics and Modeling in Mechanobiology, 2013 In this work, we introduce a modified Holzapfel-Ogden hyperelastic constitutive model for ventricular myocardium that accounts for residual stresses, and we investigate the effects of residual stresses in diastole using a magnetic resonance imaging ...

Aortic root dimension changes during systole and diastole: evaluation with ECG-gated multidetector row computed tomography [PDF]
International Journal of Cardiovascular Imaging, 2011 Cardiac pulsatility and aortic compliance may result in aortic area and diameter changes throughout the cardiac cycle in the entire aorta. Until this moment these dynamic changes could never be established in the aortic root (aortic annulus, sinuses of ...

Mean and Variability of Lipid Measurements and Risk for Development of Subclinical Left Ventricular Diastolic Dysfunction [PDF]
Diabetes & Metabolism Journal, 2022 Background Subclinical left ventricular diastolic dysfunction (LVDD) is an emerging consequence of increased insulin resistance, and dyslipidemia is one of the few correctable risk factors of LVDD. This study evaluated the role of mean and visit-to-visit

Delineation and Analysis of Seismocardiographic Systole and Diastole Profiles [PDF]
IEEE Transactions on Instrumentation and Measurement, 2020 Precise estimation of fiducial points of a seismocardiogram (SCG) signal is a challenging problem for its clinical usage. Delineation techniques proposed in the existing literature do not estimate all the clinically significant points of an SCG signal ...
