Abstract: As electronic devices become more integrated, improving thermal performance has become a key challenge in advanced packaging. In this study, we designed three honeycomb microchannels with ...

Aortic stenosis (AS) remains one of the most common forms of valve disease, with significant impact on patient survival. The disease is characterized by left ventricular outflow obstruction and ...

Background On echocardiography approximately one-third of patients with severe aortic valve stenosis based on aortic valve area (AVA<1.0 cm 2) demonstrate a non-severe mean pressure gradient (ΔPm; ≤40 ...

Calcific aortic valve disease is dramatically increasing in global burden, yet no therapy exists outside of prosthetic replacement. The increasing proportion of younger and more active patients ...

Mechanical heart valves were tested for their ability to crack under high-speed imaging, fluoroscopy, and standardized balloon testing. In vitro testing showed successful fracturing of device leaflets ...

The present study evaluated the volume and function of the left atrium by two-dimensional echocardiographic feature-tracking imaging (2D-FTI) and Simpson’s monoplanar modeling in dogs with ...
