Material transport in the left ventricle with aortic valve regurgitation [PDF]
Physical Review Fluids, 3(11), 113101 (2018), 2018 This experimental in vitro work investigates material transport properties in a model left ventricle in the case of aortic regurgitation, a valvular disease characterized by a leaking aortic valve and consequently double-jet filling within the elastic left ventricular geometry.

Assessment of aortic stiffness in computed tomography : methodology of radiological examination from 2000 to 2020 [PDF]
, 2022 Introduction: Vascular elasticity may be a predictive factor of various diseases. Although stiffening is thought to be a natural consequence of ageing, it can be accelerated by a number of pathological conditions such as hypertension, diabetes, or renal ...

Mathematical modeling of shear-activated targeted nanoparticle drug delivery for the treatment of aortic diseases [PDF]
Biomechanics and Modeling in Mechanobiology (2021), 2021 The human aorta is a high-risk area for vascular diseases, which are commonly restored by thoracic endovascular aortic repair. In this paper, we report a promising shear-activated targeted nanoparticle drug delivery strategy to assist in the treatment of coarctation of the aorta and aortic aneurysm.

Hemodynamic effects of stent-graft introducer sheath during thoracic endovascular aortic repair [PDF]
Biomechanics and Modeling in Mechanobiology (2022), 2021 Thoracic endovascular aortic repair (TEVAR) has become the standard treatment of a variety of aortic pathologies. The objective of this study is to evaluate the hemodynamic effects of stent-graft introducer sheath during TEVAR. Three idealized representative diseased aortas of aortic aneurysm, coarctation of the aorta, and aortic dissection were ...

Fluid structure interaction: Insights into biomechanical implications of endograft after thoracic endovascular aortic repair [PDF]
Computers in Biology and Medicine (2021), 2021 Thoracic endovascular aortic repair (TEVAR) has developed to be the most effective treatment for aortic diseases. This study aims to evaluate the biomechanical implications of the implanted endograft after TEVAR. We present a novel image-based, patient-specific, fluid-structure computational framework.

Comorbidities Associated with Large Abdominal Aortic Aneurysms [PDF]
, 2019 BACKGROUND: Abdominal aortic aneurysm has become increasingly important owing to demographic changes. Some other diseases, for example, cholecystolithiasis, chronic obstructive pulmonary disease, and hernias, seem to co-occur with abdominal aortic ...

Mixed Valvular Disease Following Transcatheter Aortic Valve Replacement: Quantification and Systematic Differentiation Using Clinical Measurements and Image-Based Patient‐Specific In Silico Modeling [PDF]
, 2020 Background: Mixed valvular disease (MVD), mitral regurgitation (MR) from pre‐existing disease in conjunction with paravalvular leak (PVL) following transcatheter aortic valve replacement (TAVR), is one of the most important stimuli for left ventricle (LV)

Multi-task learning for joint weakly-supervised segmentation and aortic arch anomaly classification in fetal cardiac MRI [PDF]
Machine.Learning.for.Biomedical.Imaging. 2 (2023), 2023 Congenital Heart Disease (CHD) is a group of cardiac malformations present already during fetal life, representing the prevailing category of birth defects globally. Our aim in this study is to aid 3D fetal vessel topology visualisation in aortic arch anomalies, a group which encompasses a range of conditions with significant anatomical heterogeneity ...
