Cureus, 2023 Prosthetic valve endocarditis (PVE) is an uncommon complication after heart valve replacement surgery that can result in increased morbidity and mortality. Current guidelines for management of PVE recommend antibiotic therapy followed by surgical valve replacement. The number of aortic valve replacements is expected to rise in the coming years with the

Advanced Functional Materials, EarlyView.Glyphosate (GLY) and its primary metabolite, aminomethylphosphonic acid (AMPA), are photodegraded using a poly(vinylidene fluoride) membrane with immobilized titanium dioxide (PVDF‐TiO2) in a continuous flow‐through operation under solar light. At optimized conditions, the PVDF‐TiO2 membrane achieved 95% GLY and 80% AMPA removal with •O2− as the ...

Valve-in-Valve Procedure in Failed Transcatheter Aortic Valves
JACC: Cardiovascular Imaging, 2019 Transcatheter aortic valve replacement (TAVR) is being increasingly used for the treatment of severe native aortic valve stenosis. Initially performed in patients with prohibitive or high surgical risk, TAVR is now considered as a valid alternative in patients with intermediate risk and is ...
