Transcatheter Aortic Valve Durability: Focus on Structural Valve Deterioration

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Transcatheter aortic valve replacement has emerged as a valuable alternative to surgical aortic valve replacement in patients with severe aortic stenosis. Given the expansion of transcatheter aortic valve replacement to lower‐risk and younger populations

Hybrid Magnetoactive Soft Elastomers: Material Development Toward Application in Diaphragm Pumps

Advanced Materials Technologies, EarlyView.
Hybrid magnetoactive soft elastomeric membranes are developed by combining two different types of magnetic particles. The membranes exhibit distinct mechanical, magnetic and thermal properties owing to the unique characteristics of the two magnetic particles.

Surgical approach for cardiac surgery in a patient with tracheostoma [PDF]

, 1998
The thoracic approach for cardiac surgery in a patient with a tracheostoma can result in difficult problems, such as mediastinitis, stoma necrosis or inadequate operative exposure. We present a distinct approach consisting of an incision at

Transcatheter aortic valve replacement

Nursing Critical Care, 2019
Abstract: Transcatheter aortic valve replacement (TAVR) is indicated in some patients with severe aortic stenosis for whom surgical intervention is not deemed appropriate. This article explores when TAVR may be the preferred treatment option over surgical aortic valve replacement and discusses various prosthetic valve devices.

3D Printed Multimaterial Microfluidic Transistors

Advanced Materials Technologies, EarlyView.
We introduce a biocompatible, high resolution photopolymer resin that closely mimics the Young's Modulus (elasticity) and reversible stretchability (no hysteresis) of poly(dimethylsiloxane) (PDMS), enabling the fabrication of microfluidic transistors (i.e., microvalves capable of proportional amplification) by multimaterial stereolithography (mSLA ...

Anti‐Slip Material‐Based Strategies and Approaches

Advanced Materials Technologies, EarlyView.
This review highlights the principle mechanisms of slipping at the microscale, linking contact mechanics with a friction behavior model for surface interfaces. Main strategies to develop anti‐slip properties to the surfaces are discussed alongside standardized testing approaches.
