Spontaneous Coronary Dissection: “Live Flash” Optical Coherence Tomography Guided Angioplasty

Case Reports in Cardiology, 2016
Optical Coherence tomography (OCT) is a light-based imaging modality which shows tremendous potential in the setting of coronary imaging. Spontaneous coronary artery dissection (SCAD) is an infrequent cause of acute coronary syndrome (ACS). The diagnosis

Reproducibility of Perfusion Parameters of Optic Disc and Macula in Rhesus Monkeys by Optical Coherence Tomography Angiography

Chinese Medical Journal, 2016
Background: Optical coherence tomography (OCT) angiography is a novel technique by which we can detect the local perfusion of fundus directly. The aim of this study was to evaluate the reproducibility of optic disc and macular flow perfusion parameters ...

Multimodal Imaging of Isolated Foveal Hypoplasia: A Case Report

Türk Oftalmoloji Dergisi, 2020
Foveal hypoplasia is characterized by the lack of development of a normal fovea. It may be isolated or may occur secondary to ocular conditions. Optical coherence tomography (OCT), fluorescein angiography, fundus autofluorescence, and OCT angiography may

Evaluating the Impact of Enhanced Stent Visualization on PCI Outcomes in Older Patients With Multivessel Disease

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Optimal stent expansion is a key determinant of long‐term outcomes after PCI. Intravascular imaging provides the most accurate assessment of stent deployment but remains underused, especially in older patients with MI and multivessel disease.

Detection of Post‐Stent Medial Dissection and White Thrombus Using Hybrid IVUS OCT Imaging may Help Guide Management

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT We present a 66‐year‐old undergoing ostial‐to‐mid right coronary artery (RCA) percutaneous coronary intervention (PCI) lesion proximal to an existing stent in the mid‐to‐distal segment. The patient underwent PCI, with intravascular imaging using the Novasight Hybrid IVUS OCT (Conavi, Toronto, CA) which revealed a proximal edge dissection and ...

Use of Intracoronary Pressure Wire Assessment and Association With Outcomes: Insights From the British Cardiovascular Intervention Society National Database

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Despite recommendations in international guidelines, Intracoronary pressure wire assessment (PWA) utilization remains limited in clinical practice. This study aims to describe (i) trends of PWA during Percutaneous coronary interventional (PCI), (ii) factors that predict its application, and (iii) association with in‐hospital ...

Ergonomic handheld OCT angiography probe optimized for pediatric and supine imaging.

Biomedical Optics Express, 2019
OCT angiography is a functional extension of OCT that allows for non-invasive imaging of retinal microvasculature. However, most current OCT angiography systems are tabletop systems that are typically used for imaging compliant, seated subjects.
