Vortex Shedding as a Mechanism for Free Emboli Formation in Mechanical Heart Valves [PDF]

, 1999
The high incidence of thromboembolic complications of mechanical heart valves (MHV) limits their success as permanent implants. The thrombogenicity of all MHV is primarily due to platelet activation by contact with foreign surfaces and by ...

Weathering the storms of climate change: Preparing persons with disabilities and the physiatrists who provide their care for extreme hurricanes

PM&R, EarlyView.
Abstract Climate‐driven disasters have disproportionate and often devastating consequences on individuals with disabilities. Warming ocean and air temperatures are fueling more extreme tropical cyclones, further endangering those living in at‐risk regions.

Engineering stimuli‐responsive shape‐morphing through high‐resolution 4D printing

Responsive Materials, EarlyView.
This review summarizes recent progress in high‐resolution 4D printing with smart materials and micro/nanoscale techniques. It covers actuation strategies, key applications, and future challenges for scalable, precise shape‐morphing systems. Abstract 4D printing extends conventional additive manufacturing (AM) by enabling dynamic shape‐morphing ...

In Vitro Calcification of Bioprosthetic Heart Valves: Method Validation by Comparative Heart Valve Calcification Testing

Artificial Organs, EarlyView.
We have developed a unique method for pre‐clinical heart valve prostheses evaluation of calcification propensity. Results from the test can directly be translated into improvements of prostheses design, materials, and anti‐calcification treatments, and therefore have a significant impact on heart valve prostheses quality and patient care in the future.
