POSS‐PEG‐NHS and GSH Cocrosslink DPAV to Prepare Anticalcification Bioprosthetic Scaffold With Enhanced Reendothelization, Anti‐inflammation, and Anti‐ROS

Advanced Healthcare Materials, Volume 15, Issue 30, 14 August 2026.
POSS‐PEG‐NHS and GSH cocrosslinked DPAV to prepare a multifunctional anticalcification valve substitute. This modification enhances mechanical properties, hemocompatibility, and re‐endothelialization while promoting anti‐inflammatory M2 macrophage infiltration and reducing calcification.

Microaxial Flow Pump Support as a Bridge to Transaxillary TAVI‐In‐TAVI in Cardiogenic Shock

Clinical Case Reports, Volume 14, Issue 8, August 2026.
ABSTRACT A 79‐year‐old man presented with cardiogenic shock due to severe degeneration of a prior transcatheter aortic valve. Temporary mechanical circulatory support with a transvalvular microaxial flow pump was initiated, resulting in rapid stabilization.
