We report the case of a patient with postoperative, hospital-acquired, quadruple-valve endocarditis caused by Enterococcus faecalis on presumed normal native valves. During a cervical laminectomy, the patient had a non-ST-elevation myocardial infarction that was treated conservatively. In the intensive care unit, the patient became febrile and developed a new 2/6 systolic murmur. Blood cultures grew E. faecalis, and the patient was given antibiotics. Postoperative transthoracic echocardiography and transesophageal echocardiography revealed vegetations on all 4 heart valves. Subsequently, the patient was moved to another facility and died. No autopsy was performed. E. faecalis is the third-most-common cause of bacterial endocarditis overall; however, it is rarely found in multiple-valve, hospital-acquired endocarditis. Although transthoracic echocardiography is a powerful diagnostic tool, transesophageal echocardiography increases the sensitivity and specificity to about 90%. In our patient, the diagnosis of native quadruple-valve endocarditis would not have not been made without the use of transesophageal echocardiography.
我们报告了一例患者,其术后在医院获得性粪肠球菌引起的四重瓣膜心内膜炎,推测其天然瓣膜原本正常。在颈椎椎板切除术中,该患者发生非ST段抬高型心肌梗死,接受了保守治疗。在重症监护病房,患者发热并出现新的2/6级收缩期杂音。血培养结果显示粪肠球菌生长,患者接受了抗生素治疗。术后经胸超声心动图和经食管超声心动图显示所有4个心脏瓣膜上均有赘生物。随后,患者转至另一机构并死亡。未进行尸检。粪肠球菌是细菌性心内膜炎总体上第三常见的病因;然而,在多瓣膜、医院获得性心内膜炎中很少见。尽管经胸超声心动图是一种强大的诊断工具,但经食管超声心动图可将敏感性和特异性提高至约90%。在我们的患者中,如果不使用经食管超声心动图,就无法诊断出天然四重瓣膜心内膜炎。
