Prosthetic valve endocarditis caused by silent infection of methicillin-resistant coagulase-negative staphylococci
Abstract
Surgery for prosthetic valve endocarditis in the mitral valve position is still challenging for surgeons. Reconstruction of the mitral annulus is useful for patients with a mitral annulus disputed by infection. Here, we report a redo mitral valve replacement using a collar-reinforced tissue valve, which was inserted into a mitral annulus reconstructed with a bovine patch. Though the preoperative blood culture detected Streptococcus anginosus, the intraoperative culture detected methicillin-resistant coagulase-negative staphylococci (MRCNS). MRCNS is rarely detected because of its indolent nature.
