Radial capacity and hemodynamics evaluation in vitro and implantable feasibility validation in vivo of thinner bioresorbable polymer vascular stents

BMEMat, EarlyView.
A series of in vitro experiments, numerical simulations and in vivo experiments were conducted to jointly evaluate the effects of different thicknesses of bioabsorbable polymer vascular stents on their radial capacity, hemodynamics and in vivo outcomes.

Examination of the coatings of coronary stents [PDF]

, 2006
In our study the main properties of coated coronary stents are shown, such as foreshortening, recoil, surface features and failures and the expansion properties. The types and the effects of active and passive coatings are introduced.

A Meta‐Analysis and Simplified Nomenclature for Diagonal Coronary Artery and Ramus Intermedius Across Adult and Pediatric Hearts

Clinical Anatomy, EarlyView.
ABSTRACT Anatomical descriptions of left‐sided oblique coronary branches remain inconsistent, hindering imaging interpretation and surgical planning. To quantify the prevalence, branching patterns and morphometry of the ramus intermedius (RI) and diagonal branches, and propose a unified nomenclature.

Impact of chronic outward force on arterial responses of proximal and distal of long superficial femoral artery stent

BMC Cardiovascular Disorders, 2021
Background Self-expanding nitinol stent (SENS) implantation is commonly oversized in the superficial femoral artery (SFA), and leads to chronic outward force (COF) and in-stent restenosis (ISR).

Design and testing of hydrophobic core/hydrophilic shell nano/micro particles for drug-eluting stent coating [PDF]

, 2018
In this study, we designed a novel drug-eluting coating for vascular implants consisting of a core coating of the anti-proliferative drug docetaxel (DTX) and a shell coating of the platelet glycoprotein IIb/IIIa receptor monoclonal antibody SZ-21.

Bench Testing Analysis of Perforation Management in the Setting of Bifurcation Coronary Intervention

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Management of coronary perforation in bifurcation lesions with covered stents remains challenging. Aims We aimed to describe a proper practice and toolbox for “jailed‐branch” management after covered stent deployment. Methods Using a bench model, we tested various wires with a 120° angulated microcatheter for their ability to ...

Endovascular Stenting for Pulmonary Vein Stenosis Following Atrial Fibrillation Ablation: From Diagnosis to Intervention

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Pulmonary vein stenosis (PVS) is an uncommon but serious complication of atrial fibrillation (AF) ablation, often misinterpreted as primary pulmonary disease. Timely identification is essential to prevent irreversible injury and to guide appropriate referral for interventional management. Case Presentations Through the discussion of
