A 38-year-old man with a Starr-Edwards mitral prosthetic valve presented with a Staphylococcus aureus septicemia. Twenty-four hours later, transthoracic echocardiography did not show obvious vegetations but Doppler examination of the prosthetic valve demonstrated a prolonged half pressure time and an elevated peak transmitral velocity. Seventy-two hours after the first septic event transesophageal echocardiography revealed a large annular pannus floating in the left atrium in systole and protruding in the prosthetic cage during diastole. This case report emphasizes the importance of transesophageal echocardiography in septic patients with prosthetic valves and underlines the possibility of extremely rapid pannus formation in these patients.
一名患有斯塔尔-爱德华兹二尖瓣人工瓣膜的38岁男性出现金黄色葡萄球菌败血症。24小时后，经胸超声心动图未显示明显赘生物，但人工瓣膜的多普勒检查显示半压力时间延长和二尖瓣峰值流速升高。首次败血症事件发生72小时后，经食管超声心动图显示一个大的环形血管翳在收缩期漂浮于左心房，舒张期凸入人工瓣膜笼架内。本病例报告强调了经食管超声心动图在人工瓣膜败血症患者中的重要性，并强调了这些患者中血管翳形成极快的可能性。
