A Geometrically Transient Platform for Bioelectronic Implants

Advanced Materials, EarlyView.
Minimally invasive bioelectronic implants often compromise performance for smaller sizes. To resolve this optimization dilemma, a wireless bioelectronic implant with a transient geometry is introduced (MiFi). The origami‐inspired device miniaturizes up to sixfold for syringe insertion and autonomously unfolds post‐implantation.

Plasma Metabolome Predicts Aortic Stiffness and Future Risk of Coronary Artery Disease and Mortality After 23 Years of Follow‐Up in the General Population

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Increased aortic stiffness (arteriosclerosis) is associated with early vascular aging independent of age and sex. The underlying mechanisms of early vascular aging remain largely unexplored in the general population.

Cholesterol Efflux: Does It Contribute to Aortic Stiffening?

Journal of Cardiovascular Development and Disease, 2018
Aortic stiffness during cardiac contraction is defined by the rigidity of the aorta and the elastic resistance to deformation. Recent studies suggest that aortic stiffness may be associated with changes in cholesterol efflux in endothelial cells.

Aortic stiffness: an age-related prognostic marker?

Journal of Hypertension
Aortic stiffness, a consequence of vascular aging, is an independent predictor of cardiovascular morbidity and mortality. However, the impact of age and sex on its predictive performance remains unclear. We have included 6046 individuals from the population-based Rotterdam study. Survival analyses were performed to investigate

Aortic stiffness in aortic valve stenosis: reply [PDF]

European Journal of Echocardiography, 2011
We appreciate the interest of Nemes and Forster in our article1 and we would like to warmly thank them. The main purpose of our study was to assess the relationship between aortic stiffness, left ventricular (LV) function, and BNP release in a series of patients with severe aortic stenosis (AS) and preserved LV ejection fraction. A normal control group

Large‐Scale and Cost‐Effective Fabrication of Ultra‐Thin, Biodegradable Microelectrode Arrays and Pressure Sensors Using Laser Micromachining

Advanced Materials Technologies, EarlyView.
A mask‐free and cost‐effective UV‐pico‐second laser‐based microfabrication method is proposed to fabricate large‐area biodegradable microelectrode arrays and pressure sensors. These devices demonstrate low impedance, good conformability, excellent biocompatibility, and rapid degradation, providing a new route for next‐generation transient electronics ...

Multifunctional Adhesive Hydrogel for Rapid Cardiac Hemostasis and Antibacterial Protection

Advanced Materials Technologies, EarlyView.
A multifunctional polyacrylamide/gelatin/tannic acid hydrogel (PGT) is presented for rapid cardiac hemostasis under wet, dynamic conditions. Surface tannic acid coating enables instantaneous wet adhesion, accelerates coagulation, and confers antibacterial activity within a single platform.

P93 ARE HEMODYNAMIC MEASURES ASSOCIATED WITH FRAILTY IN ELDERLY PATIENTS UNDERGOING TRANSCATHETER AORTIC VALVE IMPLANTATION?

Artery Research, 2017
Background: Aortic valve stenosis (AS) is common in the elderly and is associated with high morbidity and mortality, and leads to functional decline. The aim of this study was to investigate the possible relation between aortic stiffness, AS and frailty ...

Aortic root stiffness affects the kinematics of bioprosthetic aortic valves [PDF]

Interactive CardioVascular and Thoracic Surgery, 2016
In this study, the influence of aortic root distensibility on the haemodynamic parameters and valve kinematics of a bioprosthetic aortic valve was investigated in a controlled in vitro experiment.An Edwards INTUITY Elite 21 mm sutureless aortic valve (Edwards Lifesciences, Irvine, CA, USA) was inserted in three transparent aortic root phantoms with ...
