St Jude Medical has received a supplementary premarket approval for its SJM Masters Series mechanical heart valves. The valves feature the company's Silzone coating, a metallic silver coating which is applied to the valve sewing cuff. It reduces colonisation of microorganisms which may cause prosthetic valve endocarditis, an infection which occurs in some patients after heart valve surgery.
