Using Hydrogel Beads as a Blood Model in Optical Coherence Tomography

Current Directions in Biomedical Engineering, 2023
Optical Coherence Tomography (OCT) is a standard imaging procedure in ophthalmology. OCT Angiography is a promising extension, allowing for fast and non-invasive imaging of the retinal vasculature analyzing multiple OCT scans at the same place.

Preclinical Serial Assessment of Virtual Physiology After Implantation of a Novel Endoluminal Resorbable Fibrillated Scaffold

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background The resorbable fibrillated scaffold (RFS) is a novel electrospun, polylactide‐based endoluminal scaffold developed for peripheral arterial applications. Its porous microfibre architecture is intended to support host cell infiltration and vascular restoration.

Common carotid intima media thickness and ankle-brachial pressure index correlate with local but not global atheroma burden:a cross sectional study using whole body magnetic resonance angiography [PDF]

, 2014
Common carotid intima media thickness (CIMT) and ankle brachial pressure index (ABPI) are used as surrogate marker of atherosclerosis, and have been shown to correlate with arterial stiffness, however their correlation with global atherosclerotic burden ...

Calcified Plaque Detachment: Alternative Calcified Plaque Modification After Coronary Intravascular Lithotripsy

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Calcified plaque (CP) detachment (CD) and calcium fracture (CF) can occur following coronary intravascular lithotripsy (IVL). The extent to which CF alone facilitates stent expansion during CP modification with IVL remains unclear. Aims This study aimed to investigate the clinical implications of IVL‐induced CD.

Clinical Significance of Optical Coherence Tomography–Guided Percutaneous Coronary Intervention for In‐Stent Restenosis Within Drug‐Eluting Stents: Impact on Patient Outcomes

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background The evidence for optical coherence tomography (OCT)–guided percutaneous coronary intervention (PCI) in improving the prognosis of individuals with in‐stent restenosis (ISR) is lacking.

Evaluation of Treatment Response of Calcified Nodules and Nodular Calcified Lesions Using Mean Density on Coronary Computed Tomography Angiography

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Calcified nodules (CN) and nodular calcifications (NC) present significant challenges during percutaneous coronary intervention (PCI) because of their protruding morphology and high rigidity, which often result in inadequate stent expansion and suboptimal procedural outcomes.
