Vorticity‐Facilitated Platelet Aggregation: a High Expansion‐Ratio Stenotic Microfluidic Platform Unravels the Role of Complex Flow Dynamics in Arterial Thrombosis

Advanced Healthcare Materials, EarlyView.
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 ...

Coronary Artery Centerline Extraction in Cardiac CT Angiography Using a CNN-Based Orientation Classifier

, 2018
Coronary artery centerline extraction in cardiac CT angiography (CCTA) images is a prerequisite for evaluation of stenoses and atherosclerotic plaque. We propose an algorithm that extracts coronary artery centerlines in CCTA using a convolutional neural ...

Nitric Oxide‐Releasing Catheters with Phenol‐Amine Catalytic Coatings for Improved Anti‐Inflammatory Performance

Advanced Healthcare Materials, EarlyView.
Tannic acid‐selenocystamine (TA‐SeCA) nanocoating enables stable, sustained catalytic nitric oxide (NO) release on catheter surfaces. This one‐step phenol‐amine coating improves catheter functionality by enhancing endogenous NO production, supporting vascular function, and reducing inflammation.

The relationship between mechanical dyssynchrony of the left ventricular myocardium and the number of affected coronary arteries in patients with coronary heart disease who underwent revascularization

Journal of V. N. Karazin Kharkiv National University: Series Medicine
Background. A promising method for early detection of myocardial dysfunction is the evaluation of mechanical dyssynchrony of the left ventricular myocardium, the prognostic value of which in the diagnosis of 3-vessel lesions was shown only in a single ...

Novel Drug‐Testing Platform for Vascular Injury‐induced Intimal Hyperplasia Using a Microphysiological System

Advanced Healthcare Materials, EarlyView.
This study develops a 3D vascular injury model using a microphysiological system that mimics key features of intimal hyperplasia. Antiproliferative drugs reduced VSMC proliferation but worsened endothelialdenudation. A combination of diphenyleneiodonium and quercetin effectively reduced proliferation and migration of VSMC and inflammation while ...

Assessment of coronary artery outward remodeling in consequence of excision of epicardial adipose tissue in Ossabaw swine [PDF]

, 2017
Background Coronary artery disease (CAD) results from the buildup of cholesterol, inflammatory factors, and proliferating smooth muscle cells within a vessel wall. This plaque impedes on the vessel lumen, decreasing the space through which blood can flow,

Programmable Compliance in Small‐Diameter Vascular Grafts by Design of Melt‐Electrowritten Scaffold Architectures for In Situ Tissue Engineering

Advanced Healthcare Materials, EarlyView.
Small‐diameter vascular grafts with compliance tunable by design are fabricated via melt electrowriting. By controlling the winding angle of intertwined helical fibers, grafts with compliances matching those of human vessels, from veins to arteries, are realized. This holds the potential of avoiding a compliance mismatch, which has been identified as a
