Transcatheter Aortic Valve Replacement in Aortic Stenosis: a Clinical Case
Background. Aortic valve stenosis is common with prevalence of about 0.5 %, peaking in people aged over 70 years mostly due to age-related valve calcification. The year 2002 was marked by the invention and use of the endovascular aortic replacement valve

This study reveals how vorticity—a swirling flow pattern—enhances platelet aggregation and thrombus formation in high‐shear conditions. Using a custom microfluidic model, it is shows that vorticity promotes vWF–GPIbα interactions and calcium signaling, providing new insights into thrombosis mechanobiology and informing safer blood‐contacting medical ...

Miniaturized Devices for On‐the‐Spot Generation of Small‐Diameter Vascular Grafts
An intracorporeal extrusion device is developed for on‐the‐spot generation of vascular grafts with tunable diameters spanning from 1 to 6 mm. The device uses biomimetic polymers and light, to promptly obtaining biocompatible and high‐burst pressure‐resistant grafts.

Non‐Invasive Diagnosis of Hypertrophic Cardiomyopathy by Breath
The use of sensor technologies for the diagnosis of hypertrophic cardiomyopathy (HCM) by identification of volatile organic compounds (VOCs) in breath samples. By combining gas chromatography‐mass spectrometry (GC‐MS) and electronic nose (eNose) platforms, specific VOC patterns associated with HCM are detected and analyzed.
