Intravascular ultrasound imaging as a novel tool for the diagnosis of endofibrosis

Journal of Vascular Surgery Cases and Innovative Techniques, 2016
Given the rise of high-intensity sport athletes and the paucity of literature on endofibrosis, we describe a novel adjunctive imaging technique to aid in diagnosis. A 41-year-old female triathlete presented with exercise-limiting claudication. Results of

Bio‐Inspired Micro‐Fin‐Assisted Multi‐Modal Vascular Intervention

Advanced Science, EarlyView.
A magnetic guidewire with a micro‐fin–integrated tip is introduced for multimodal cardiovascular navigation. The micro‐fins exploit fluid drag to augment magnetic torque, enabling bifurcation traversal at 15 mT, tolerating 45° misalignment, bidirectional crawling, and buckle self‐correction.

A new approach for improving coronary plaque component analysis based on intravascular ultrasound images [PDF]

, 2010
Virtual histology intravascular ultrasound (VH-IVUS) is a clinically available technique for atherosclerosis plaque characterization. It, however, suffers from a poor longitudinal resolution due to electrocardiogram (ECG)-gated acquisition.

Monocyte‐Differentiation‐Activated Fluorescent “Scout” Probe for Precise in Vivo Detection of Vulnerable Plaque

Advanced Science, EarlyView.
An innovative monocyte‐differentiation‐activated fluorescent “scout” probe (MDAF) leverages the inherent chemotaxis of monocytes toward vulnerable plaques (VAP) to enable efficient targeted delivery while achieving spatiotemporally controllable activation of its AIE fluorescent signals with the dynamic differentiation of monocytes, providing an ...

Soft‐Drug‐Inspired MnSTF Nano‐Adjuvant for Safe and Synergistic cGAS–STING Activation in Tumor Immunotherapy

Advanced Science, EarlyView.
This study introduces MnSTF, a soft‐drug‐inspired nanoadjuvant that overcomes the systemic toxicity of STING agonists. Through Mn2+ coordination with an ENPP1 inhibitor, it enables safe cGAS‐STING activation, remodels the tumor immune microenvironment, and synergizes with radiotherapy or vaccines to elicit robust antitumor immunity.

Functional Versus Anatomic Assessment of Myocardial Bridging by Intravascular Ultrasound: Impact of Arterial Compression on Proximal Atherosclerotic Plaque

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016
BackgroundThe presence of a myocardial bridge (MB) has been shown to promote atherosclerotic plaque formation proximal to the MB, presumably because of hemodynamic disturbances provoked by retrograde blood flow toward this segment in cardiac systole.
