Antimicrobial Activity of Prosthetic Heart Valve Sewing Cuffs Coated With Minocycline and Rifampin

摘要

Prosthetic heart valve sewing cuffs coated with minocycline and rifampin exhibited in vitro zones of inhibition against all 52 tested clinical isolates responsible for prosthetic valve endocarditis. An in vitro elution study of these coated sewing cuffs demonstrated residual zones of inhibition against Staphylococcus epidermidis for at least 4 weeks.
