Adaptive 4D‐Printed Vascular Stents With Low‐Temperature‐Activated and Intelligent Deployment

open access: yesAdvanced Functional Materials, EarlyView.
Microarchitected coronary artery stents were fabricated using a polycaprolactone (PCL)‐based shape memory polymer (SMP) composite via projection micro‐stereolithography (PµSL) 4D printing. By incorporating diethyl phthalate (DEP) as a plasticizer, the thermal transition temperature (Ttran) was modulated to about 37°C, enabling rapid and autonomous ...

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

open access: yesJournal 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 ...

Drug‐Free Thrombolysis Mediated by Physically Activated Micro/Nanoparticles

open access: yesAdvanced Functional Materials, EarlyView.
Overview of particle‐mediated thrombolytic effects (thermal, mechanical, and chemical) and their activating physical stimuli (light, ultrasound, and magnetic field) in drug‐free thrombolysis. ABSTRACT Thrombus‐associated disorders rank among the world's leading causes of death, with ischemic heart disease and stroke as the main contributors.

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

open access: yes, 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,

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

open access: yes, 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 ...

Mechanical properties of human coronary arteries

open access: yes2010 Annual International Conference of the IEEE Engineering in Medicine and Biology, 2010
The lack of reliable mechanical data on coronary arteries and, more specifically, on their wall strength hampers the application of numerical models and simulations to vascular problems, and precludes physicians from knowing in advance the response of ...
