Three-dimensional reconstruction of coronary arteries and plaque morphology using CT angiography – comparison and registration with IVUS

BMC Medical Imaging, 2016
BackgroundThe aim of this study is to present a new methodology for three-dimensional (3D) reconstruction of coronary arteries and plaque morphology using Computed Tomography Angiography (CTA).MethodsThe methodology is summarized in six stages: 1) pre ...

Clinical Impact of Concordant and Discordant Physiology Parameters Post‐Percutaneous Coronary Intervention in the EASY‐PREDICT Study

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background In the EASY‐PREDICT Study, patients were randomized to angiography‐guidance or post‐percutaneous coronary intervention (PCI) physiology‐guidance. Discordance between resting and hyperemic physiology post‐PCI might have a different relationship with clinical outcomes.

New Insights into Intravascular Imaging of Coronary Bifurcation Lesions and Left Main Stenosis: What Have We Accomplished?

Cardiology Discovery, 2022
Coronary bifurcation lesions (CBL) are one of the most challenging lesions to treat in interventional cardiology. Intravascular imaging including intravascular ultrasound (IVUS) and optical coherence tomography (OCT) is paramount for the assessment of ...

A Comparison of a Drug Coated Balloon With Drug Eluting Stent Strategy for Treating Coronary Bifurcation Lesions

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background The treatment of coronary bifurcation lesions (CBL) remains complex and associated with a higher rate of long‐term adverse cardiovascular events due to anatomical and procedural complexity. Aims We compared procedural outcomes between a drug coated balloon (DCB) only approach and a 2nd generation drug eluting stent (DES) for ...

Intravascular ultrasound imaging in evaluation of aortic stiffness: A proof-of-concept study

Cardiology Journal, 2023
BACKGROUND: Aortic stiffness is a well-known cardio-vascular risk factor. For years, different methods have been studied in the assessment of aortic elastic properties and large arterial stiffness for risk stratification.

Guidewire Manipulation Based on Establishment of Stereo Perception in Percutaneous Coronary Intervention

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Traditional percutaneous coronary intervention (PCI) relies on two‐dimensional X‐ray imaging, but this does not allow depth perception and complicates precise manipulation of the guidewire. Our purpose was to develop a novel method for guidewire manipulation by establishing stereoscopic perception in coronary angiography (CAG), as ...

OCT‐Guided Distal Left Main Bifurcation PCI: Mid‐Term Outcomes From a Multicenter South‐Asian Registry

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Optical coherence tomography (OCT)‐guided percutaneous coronary intervention (PCI) enhances treatment of complex coronary artery lesions, including left main (LM) disease, by enabling lesion morphology assessment and stent optimization, thereby reducing major adverse cardiac events (MACE).

Amplification of Light‐Ultrasound Interaction in a Pi‐Shifted Fiber Bragg Grating for Enhanced Ultrasonic Sensitivity

Laser &Photonics Reviews, EarlyView.
By precisely engineering the geometry of a fiber‐based optical resonator, the interaction between confined light and external ultrasound waves is significantly amplified without sacrificing light confinement, boosting the ultrasound detection sensitivity beyond 0.5 mPa/√Hz.

The beneficial role of intravascular ultrasound in the diagnosis and treatment of nonthrombotic iliac venous obstructions as compared with traditional venography in the Chinese population

Vascular Investigation and Therapy, 2020
PURPOSE: The efficacy of intravascular ultrasound (IVUS) in diagnosing obstructive venous lesions has been established in the Western countries; however, its beneficial role in the Asian population is seldom reported.
