Intravascular Lithotripsy for Coral Reef Aorta and Chronic Mesenteric Ischemia: Case Report and Comprehensive Literature Review

Catheterization and Cardiovascular Interventions, Volume 106, Issue 6, Page 3331-3339, November 15, 2025.
ABSTRACT Chronic mesenteric ischemia (CMI) secondary to extensive paravisceral atherosclerosis is a rare but challenging vascular condition, often presenting with postprandial abdominal pain, weight loss, and claudication due to impaired blood flow. While surgical bypass is a standard treatment, it carries significant risks, particularly in patients ...

Balloon Uncrossable Left Main Coronary Artery Dissection: A Case Report and Literature Review

Clinical Case Reports, Volume 13, Issue 11, November 2025.
ABSTRACT Coronary artery dissection presents a high‐risk scenario, particularly when complicated by severe calcification. We report a complex case of a balloon‐uncrossable lesion encountered during percutaneous coronary intervention (PCI) of a calcified ostial‐to‐mid left anterior descending (LAD) artery lesion extending into the LMCA.

Proprotein Convertase Subtilisin/Kexin Type 9 (PCSK9): The Multifaceted Biology, Diseases, and Pharmaceutical Interventions

MedComm, Volume 6, Issue 11, November 2025.
Summary of PCSK9 inhibitor mechanisms. PCSK9 inhibitors (PCSK9‐i) primarily lower LDL‐cholesterol (LDL‐C) by blocking PCSK9‐mediated degradation of hepatic LDL receptors (LDLR), enhancing LDL clearance. Beyond LDLR‐dependent effects, PCSK9‐i exert multiple benefits via LDLR‐independent pathways.

Real‐Time Monitoring of Atherosclerotic Plaque Using β‐Galactosidase‐Activated Photoacoustic Tomography

Small, Volume 21, Issue 44, November 6, 2025.
Detecting Vascular Senescence: Novel Enzyme‐Responsive Photoacoustic Nanoprobes for Atherosclerotic Plaque Imaging. A lipid nanoprobe is developed that detects senescence‐associated β‐galactosidase in plaques via enzyme‐triggered spectral shifts. This platform enables dynamic tracking of atherosclerotic progression, 3D visualization on the extent and ...

Intravascular ultrasound-derived virtual fractional flow reserve in the superficial femoral artery

CVIR Endovascular
Background Fractional flow reserve (FFR) can be estimated by analysis of intravascular imaging in a coronary artery; however, there are no data for estimated FFR in an extremity artery. The aim of this concept-generating study was to determine whether it

Intravascular ultrasound-guided interventions in coronary artery disease: a systematic literature review, with decision-analytic modelling, of outcomes and cost-effectiveness.

Health Technology Assessment, 2000
BACKGROUND: Intravascular ultrasound (IVUS) is the generic name for any ultrasound technology used in vivo within the blood vessels. More specifically, intracoronary ultrasound enables imaging of the coronary arteries from within the lumen.
