Intravascular lithotripsy (IVL) enabled the percutaneous closure of a severely calcified paravalvular leak regurgitation following implantation of a self-expandable transcatheter aortic valve: a case report

open access: yesFrontiers in Cardiovascular Medicine
BackgroundClosure of paravalvular leak (PVL) regurgitation after self-expandable (SE) transcatheter aortic valve implantation (TAVI) may be more challenging than after balloon-expandable (BE) valve implantation.Case summaryAn 85-year-old woman suffering ...

Coronary artery grafting in infants [PDF]

open access: yes, 2009
Coronary artery bypass grafting (CABG) with cardiac vale repair is an uncommon surgery in infants. CABG is technically demanding in infants due to the small size not only of the coronary arteries but also the potential graft arteries.

A Nano‐Interception Strategy for Chronic Heart Failure: Prussian Blue Nanoparticles Disrupt Fibroblast‐Immune Communication via CCL2 Sequestration

open access: yesAdvanced Materials, EarlyView.
A nano‐interception strategy disrupts pathogenic fibroblast–macrophage crosstalk in chronic heart failure. Scalable Prussian blue nanoparticles selectively sequester CCL2 via ultrahigh‐affinity binding, preventing CCR2+ macrophage recruitment and breaking a key fibro‐inflammatory circuit. This approach demonstrates robust efficacy in murine and porcine

Engineered Heparinized GQDS/HPEI–Polyamide Membrane for Bilirubin Removal via One Step Anti Coagulation

open access: yesAdvanced Materials Interfaces, EarlyView.
A multifunctional heparinized polyamide membrane embedded with graphene quantum dots (GQDs) and hyperbranched polyethyleneimine (HPEI) is engineered for efficient bilirubin removal via a one‐step anticoagulation–adsorption process. The membrane demonstrates enhanced hemocompatibility, prolonged clotting times, and high bilirubin adsorption capacity ...

Nitric Oxide‐Generating Poly (allylamine hydrochloride) Coating on Biomedical Titanium Implant

open access: yesAdvanced Materials Interfaces, EarlyView.
We report a metal‐free, nitric oxide (NO)‐generating coating in which poly(allylamine hydrochloride) (PAH) is covalently immobilized onto titanium. The coating catalyzes NO generation from the endogenous S‐nitrosothiol GSNO, retains activity after multiple reuse cycles and pH exposures, and maintains endothelial cell viability while modulating ...

Magnetically Actuated Drops‐on‐Stilts Microrobots for Transport and Delivery of Hydrophobic Cargo

open access: yesAdvanced Materials Interfaces, EarlyView.
Iron oxide nanoparticles and oil droplets in external magnetic fields form “drops‐on‐stilts” microrobots that transport hydrophobic cargo. Tunable nanoparticle–droplet interactions generate stilt‐like structures. Field rotation enables walking, obstacle navigation, and collective motion.

Enhanced Infection Resistance and Regenerative Healing of Titanium Implants via Peptide‐Loaded Biodegradable Coatings

open access: yesAdvanced Materials Technologies, EarlyView.
This study presents a new biodegradable coating for titanium implants using a natural antimicrobial peptide, caerin 1.9. Applied via solvent casting, the coating offers sustained antibacterial protection and promotes healing. Tested on 3D‐printed porous titanium scaffolds, it effectively prevented infection—including against resistant bacteria—while ...
