Spectral characteristics of the internal jugular vein and central venous pressure pulses: a proof of concept study

Veins and Lymphatics, 2021
In this proof-of-concept study the impact of central venous pressure (CVP) on internal jugular veins cross-sectional area (CSA) and blood flow time-average velocity (TAV) was evaluated in eight subjects, with the aim of understanding the drivers of the ...

Noncanonical atherosclerosis as the driving force in tricuspid aortic valve associated aneurysms - A trace collection

Journal of Lipid Research, 2023
Pathogenic mechanisms in degenerative thoracic aortic aneurysms (TAA) are still unclear. There is an ongoing debate about whether TAAs are caused by uniform or distinct processes, which would obviously have a major impact on future treatment strategies ...

Subclinical Leaflets Thrombosis After Transcatheter Replacement of Bicuspid vs. Tricuspid Aortic Valve

Frontiers in Cardiovascular Medicine, 2021
Background: Subclinical leaflet thrombosis (SLT) is an important sequela that compromises the durability of the bioprosthetic valve.Objectives: To better determine the effect of SLT in bicuspid aortic valve (BAV), we performed a retrospective assessment ...

The Expression Level of the 3a Movement Protein Determines Differences in Severity of Symptoms Between Two Strains of Tomato Aspermy Cucumovirus

Molecular Plant-Microbe Interactions, 1997
Two strains of tomato aspermy cucumovirus, 1-TAV and V-TAV, differ in the severity of the symptoms induced in Nicotiana tabacum: 1-TAV induces a severe chlorotic mottle that appears 5 days post inoculation (d.p.i.) in the second systemic leaf, while V ...

Understanding TAVR device expansion as it relates to morphology of the bicuspid aortic valve: A simulation study.

PLoS ONE, 2021
The bicuspid aortic valve (BAV) is a common and heterogeneous congenital heart abnormality that is often complicated by aortic stenosis. Although initially developed for tricuspid aortic valves (TAV), transcatheter aortic valve replacement (TAVR) devices
