Use of intravascular ultrasound for optimal vessel sizing in chronic total occlusion percutaneous coronary intervention

Frontiers in Cardiovascular Medicine, 2022
AimThe aim of this study is to provide evidence on how use of standardized intravascular ultrasound (IVUS) use impacts stent size choice in the setting of chronic total occlusion (CTO) percutaneous coronary intervention (PCI) compared to visual ...

CLASSIFICATION OF INTRAVASCULAR ULTRASOUND IMAGES BASED ON NON-NEGATIVE MATRIX FACTORIZATION FEATURES AND MAXIMUM LIKELIHOOD CLASSIFIER

International Journal of Advances in Signal and Image Sciences, 2018
The amount of plaque in coronary arteries in any particular point is identified by the IntraVascular UltraSound (IVUS) images. The classification of IVUS images is very important to diagnose various coronary artery diseases.

Diagnostic Performance of 60 MHz High-Definition Intravascular Ultrasound versus Fourier Domain Optical Coherence Tomography for Identifying Plaque Rupture, Plaque Erosion, and Thrombosis in a Rabbit Model

Reviews in Cardiovascular Medicine, 2023
Background: Most acute coronary syndromes occur due to coronary thrombosis caused by plaque rupture (PR) and plaque erosion (PE). Precise in vivo differentiation between PR and PE is challenging for intravascular imaging.

PMN-PT Single Crystal Ultrasonic Transducer With Half-Concave Geometric Design for IVUS Imaging

IEEE Transactions on Biomedical Engineering, 2018
As the key component of intravascular ultrasound (IVUS) imaging systems, traditional commercial side-looking IVUS transducers are flat and unfocused, which limits their lateral resolution.

Efficacy of navigating through the intraplaque route using AnteOwl WR intravascular ultrasound in femoropopliteal chronic total occlusion

CVIR Endovascular, 2021
Background There is no consensus on the optimal guidewire passage route for femoropopliteal (FP) chronic total occlusion (CTO). If intraplaque wiring can be performed, a stent-less strategy using a drug-coated balloon can be realized even with FP CTO ...

Structural Phase Separation and Enhanced Superconductivity in La1.875Ba0.125CuO4 Under Uniaxial Strain

Advanced Materials, EarlyView.
Uniaxial strain is used to tune electronic, structural, and magnetic order in a copper oxide superconductor. Application of a moderate uniaxial strain condition across the low‐temperature orthorhombic‐to‐tetragonal transition creates a condition that disrupts the usual stripe ordering.

The diagnostic role of IVUS in pelvic venous disease

Turkish Journal of Vascular Surgery, 2021
The two main mechanisms for pelvic venous disease (PeVD) are reflux of ovarian vein and obstruction of left common iliac or left renal vein. Some patients have a combination of the two.
