Bench Testing Analysis of Perforation Management in the Setting of Bifurcation Coronary Intervention. [PDF]

Catheter Cardiovasc Interv
ABSTRACT Background Management of coronary perforation in bifurcation lesions with covered stents remains challenging. Aims We aimed to describe a proper practice and toolbox for “jailed‐branch” management after covered stent deployment. Methods Using a bench model, we tested various wires with a 120° angulated microcatheter for their ability to ...

Serial Change and Clinical Impact of Irregular Protrusion in Lesions With Chronic Coronary Syndrome. [PDF]

Catheter Cardiovasc Interv
ABSTRACT Background The changes over time and effects on long‐term clinical outcomes beyond 1 year of irregular protrusion (IP) in chronic coronary syndrome (CCS) remains unclear. Aims This study aimed to assess the time‐dependent change and long‐term clinical impact of IP in CCS lesions.

Coronary arterial repair in patients with stable angina pectoris or acute coronary syndrome after ultrathin biodegradable polymer sirolimus‐eluting stent implantation at 1‐year follow‐up by coronary angioscopy

Catheterization and Cardiovascular Interventions, Volume 102, Issue 6, Page 1012-1019, November 15, 2023., 2023
Abstract Background Imaging modality‐based evidence is limited that compares the extent of coronary arterial repair after percutaneous coronary intervention between patients with stable angina pectoris (SAP) and those with acute coronary syndrome (ACS). Methods Between December 2018 and November 2021, a single‐center, nonrandomized, observational study

Use of Optical Coherence Tomography in Dentistry

International Journal of Dentistry, Volume 2023, Issue 1, 2023., 2023
Optical coherence tomography (OCT) is an optics‐based imaging technique, which may be called an “optical biopsy.” It can be used to acquire structural information about a tissue at a resolution comparable to histopathology. OCT is based on the principle of low‐coherence interferometry where near‐infrared (NIR) light is shown on a tissue sample and then

Cardiac Computed Tomography Assessment of the Variation of Papillary Muscle Morphology before Mitral Valve Surgery

Journal of Cardiac Surgery, Volume 2023, Issue 1, 2023., 2023
Background. The morphology of the papillary muscles of the left ventricle is highly variable. Few studies have investigated papillary muscle morphology using imaging. Objective. This study aimed to assess papillary muscle morphology with primary mitral regurgitation (MR) using cardiac computed tomography (CT). Methods.

2022 Update of the Consensus on the Rational Use of Antithrombotics and Thrombolytics in Veterinary Critical Care (CURATIVE) Domain 6: Defining rational use of thrombolytics

Journal of Veterinary Emergency and Critical Care, Volume 32, Issue 4, Page 446-470, July/August 2022., 2022
Abstract Objectives To systematically review available evidence and establish guidelines related to the use of thrombolytics for the management of small animals with suspected or confirmed thrombosis. Design PICO (Population, Intervention, Control, and Outcome) questions were formulated, and worksheets completed as part of a standardized and systematic

Full‐Color Metaoptical Imaging in Visible Light

Advanced Photonics Research, Volume 3, Issue 5, May 2022., 2022
Meta‐optics has emerged as an attractive platform for miniaturizing imaging systems. Despite progress, the meta‐optical imaging systems suffer from strong chromatic aberrations. Herein, the challenges, progress, and opportunities on full‐color imaging using the visible light using meta‐optics are reviewed.

Evidence‐Based Nursing Model in Interventional Thrombolysis for Acute Lower Extremity Arterial Embolism

Contrast Media &Molecular Imaging, Volume 2022, Issue 1, 2022., 2022
Acute lower extremity arterial embolism (AE) is a serious clinical emergency, and, if not treated in time, it can easily lead to limb ischemia and necrosis and eventually facing amputation, which seriously damages patients' physical and mental health.
