A poly(hydroxy‐oxazolidone) (PHOx) is synthesized from CO2‐based precursors, enabling the up‐cycling of this waste material. After synthesis, PHOx shows thermoplastic properties, and can therefore be processed by many temperature‐dependent techniques. PHOx is hemocompatible, anti‐adhesive, and biocompatible, which is demonstrated in vitro and in vivo ...

Left atrial anomalous muscular band as incidental finding during video-assisted mitral surgery [PDF]
Congenital fibromuscular bands have been described inleft ventricle or right atrium and have been diagnosed by echocardiography and CT scan. The first report of anomalous band in the left atrium was described in 1897 by Rollestone (1).

Dynamic Echocardiographic Imaging of a Valve-in-Valve Mitral Prosthesis
Dynamic imaging of heart valves and specifically prosthetic valves is a central benefit of echocardiography. Most bioprosthetic heart valves degenerate over a given time and hence require repeat valve replacement which carries a significant risk of ...
