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 , the intraoperative culture detected methicillin-resistant coagulase-negative staphylococci (MRCNS). MRCNS is rarely detected because of its indolent nature.
摘要
对于外科医生来说，二尖瓣位置的人工瓣膜心内膜炎的手术仍然具有挑战性。对于二尖瓣环有感染争议的患者，重建二尖瓣环是有用的。在这里，我们报告了一例使用带领加强组织瓣膜的二尖瓣再次置换术，该瓣膜插入到用牛心包片重建的二尖瓣环中。尽管术前血培养检测到 ，但术中培养检测到耐甲氧西林凝固酶阴性葡萄球菌（MRCNS）。由于其惰性，MRCNS 很少被检测到。
