Correlation of Intravascular Ultrasound with Histology in Pediatric Pulmonary Vein Stenosis

Children, 2021
Preliminary intravascular ultrasound (IVUS) images of suspected pediatric intraluminal pulmonary vein stenosis (PVS) demonstrate wall thickening. It is unclear how the IVUS-delineated constituents of wall thickening correlate with the histology.

Intravascular Ultrasound in the Endovascular Treatment of Patients With Peripheral Arterial Disease: Current Role and Future Perspectives

Frontiers in Cardiovascular Medicine, 2020
Over the last decade, intravascular ultrasound (IVUS) has emerged as a useful adjunctive tool to angiography in an increasing number of catheter-based procedures for peripheral arterial disease (PAD). IVUS catheters offer accurate cross-sectional imaging

A Prospective, Multicenter, Open Label Study Investigating the Implementation of a Standardized Algorithm for Coronary CaLcificatiOn With PlaquE Modification Using UltraSound Guidance to Improve Procedural and Clinical Outcomes (CYCLOPES): Design and Rationale of the CYCLOPES Trial. [PDF]

Catheter Cardiovasc Interv
ABSTRACT Introduction Moderate‐to‐severe calcification is present in ~20%–30% of patients undergoing coronary angiography. Coronary lesion modification is often necessary to facilitate optimal stent delivery and expansion, with several dedicated devices now approved for calcium modification before stent implantation. The CYCLOPES study aims to evaluate

Stent boost enhancement compared to intravascular ultrasound in the evaluation of stent expansion in elective percutaneous coronary interventions

The Egyptian Heart Journal, 2018
Background: Stent underexpansion is a major risk factor for in-stent restenosis and acute in-stent thrombosis1Intravascular ultrasound (IVUS) is one of the standards for detection of stent underexpansion (de Feyter et al.

In-hospital outcomes of angiography versus intravascular ultrasound-guided percutaneous coronary intervention in ST-elevation myocardial infarction patients

Journal of Community Hospital Internal Medicine Perspectives, 2020
Background We compared the in-hospital complications, outcomes, cost, and length of stay (LOS) between angiography-guided percutaneous coronary intervention (PCI) and intravascular ultrasound (IVUS)-guided PCI in patients with ST-elevation myocardial ...

Using Optical Coherence Tomography and Intravascular Ultrasound Imaging to Quantify Coronary Plaque Cap Stress/Strain and Progression: A Follow-Up Study Using 3D Thin-Layer Models

Frontiers in Bioengineering and Biotechnology, 2021
Accurate plaque cap thickness quantification and cap stress/strain calculations are of fundamental importance for vulnerable plaque research. To overcome uncertainties due to intravascular ultrasound (IVUS) resolution limitation, IVUS and optical ...

Automatic detection of vessel structure by deep learning using intravascular ultrasound images of the coronary arteries

PLoS ONE, 2021
Intravascular ultrasound (IVUS) is a diagnostic modality used during percutaneous coronary intervention. However, specialist skills are required to interpret IVUS images. To address this issue, we developed a new artificial intelligence (AI) program that
