Bilateral cardiac sympathetic denervation on an ECMO patient for refractory ventricular arrhythmia: A case report.

Genetic syndrome such as Brugada syndrome can lead to lethal ventricular arrhythmias. Cardiac sympathetic denervation has been shown to be effective in ameliorating refractory ventricular arrhythmias. We present a 33-year-old black female with a medical history of Brugada syndrome with an implantable cardiac defibrillator who presented with refractory ventricular tachycardia leading to cardiogenic shock, requiring extracorporeal membrane oxygenation.

Dextran hydrogels by crosslinking with amino acid diamines and their viscoelastic properties.

Amine functionalized polysaccharide hydrogels such as those based on chitosan are widely examined as biomaterials. Here we set out to develop a facile procedure for developing such hydrogels by crosslinking dextran with amino acid diamines. The dextran-amino acid gels were formed by the addition of the amino acid diamines to a dextran and epichlorohydrin solution once it became homogeneous.
