Optical Coherence Tomography and Optical Coherence Tomography Angiography in Pediatric Retinal Diseases

Diagnostics, 2023
Indirect ophthalmoscopy and handheld retinal imaging are the most common and traditional modalities for the evaluation and documentation of the pediatric fundus, especially for pre-verbal children. Optical coherence tomography (OCT) allows for in vivo visualization that resembles histology, and optical coherence tomography angiography (OCTA) allows for

Treatment of Coronary Perforation in a Bifurcation: Two‐Stent Strategies With Fenestrated Covered Stents

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Coronary perforations are a dreaded complication for any interventional cardiologist. The treatment of this complication is exceptionally difficult when it occurs in a coronary bifurcation. While a conservative approach or a balloon occlusion might be sufficient in some cases, additional treatment is sometimes necessary.

OPTICAL COHERENCE TOMOGRAPHY AND OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY IN OPHTHALMOLOGY

The Polish Journal of Aviation Medicine, Bioengineering and Psychology, 2023
Abstract: Optical coherence tomography is a non-invasive method of imagining the anterior and the posterior segment of the eye. It is commonly used in ophthalmic practice to diagnose and monitor various pathologies of the eyeball. Optical coherence tomography angiography (OCTA) is a useful tool to visualize the entire retinal and choroidal ...

Coronary Slow Flow and No‐Reflow During Percutaneous Coronary Intervention: Contemporary Insights Into Imaging‐Guided Prediction, Prevention, and Management

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Coronary slow flow (SF) and no‐reflow (NR) are clinically significant complications of percutaneous coronary intervention (PCI), particularly in ST‐segment elevation myocardial infarction (STEMI) and saphenous vein graft (SVG) interventions. Angiographically defined as impaired myocardial perfusion despite restored epicardial patency, SF/NR ...

In vivo laser Doppler holography of the human retina

, 2018
The eye offers a unique opportunity for non-invasive exploration of cardiovascular diseases. Optical angiography in the retina requires sensitive measurements, which hinders conventional full-field laser Doppler imaging schemes.

Feasibility and Safety of the ETcath200 Robotic PCI System for Complex Coronary Lesions: A Prospective Single‐Center Study

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background International robotic‐assisted PCI platforms such as CorPath 200 and CorPath GRX have demonstrated procedural safety and efficacy but are limited by the absence of real‐time tactile feedback and cumbersome device exchange. The ETcath200, the first domestically developed robotic PCI system in China, introduces guidewire force‐sensing
