Unique angiographic findings in a patient with myocardial ischemia and immunoglobulin G4-related disease

SAGE Open Medical Case Reports, 2017
Immunoglobulin G4-related disease characteristically involves multiple organs including the heart and coronary arteries. Immunoglobulin G4-related coronary artery disease is thought to be due to periarteritis and histopathologically is characterized by ...

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

Coronary Intravascular Ultrasound

Microscopy and Microanalysis, 1997
Abstract For several decades, contrast angiography has served as the principal imaging modality used to assess the anatomic severity of coronary artery disease. Recent technical advances in acoustics and microelectonics have permitted development and refinement of miniaturized ultrasound devices capable of real-time tomographic coronary ...

Microendovascular Neural Recording from Cortical and Deep Vessels with High Precision and Minimal Invasiveness

Advanced Intelligent Systems, EarlyView.
Intravascular electroencephalography (ivEEG) using micro‐intravascular electrodes was developed. Cortical‐vein ivEEG showed a higher signal‐to‐noise ratio and finer spatial resolution of somatosensory evoked potentials (SEPs) than superior sagittal sinus ivEEG, and deep‐vein ivEEG captured clear visual evoked potentials.

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.

Intravascular ultrasound chirp imaging

Applied Physics Letters, 2012
We demonstrate the feasibility of intravascular ultrasound (IVUS) chirp imaging as well as chirp reversal ultrasound contrast imaging at intravascular ultrasound frequency. Chirp excitations were emitted with a 34 MHz single crystal intravascular transducer and compared to conventional Gaussian-shaped pulses of equal acoustic pressure.
