Rare but potentially fatal, brucellosis prosthetic valve endocarditis is a complication of brucellosis caused by Brucella species. The symptoms of brucellosis can be nonspecific, making the diagnosis challenging. Osteoarticular involvement is the most common complication of brucellosis. Mortality from brucellosis is low except for endocarditis and involvement of the central nervous system. The diagnosis is based on laboratory tests and clinical manifestations. Serological tests are preferred, as culture methods can be unreliable. A 59-year-old woman presented with gastrointestinal bleeding, fever, anorexia and malaise. She had a history of aortic valve replacement with a mechanical prosthesis for severe bicuspid aortic stenosis. Investigations revealed a multiloculated aortic root abscess encircling the prosthetic valve. She was diagnosed with brucella endocarditis, treated with antibiotics and underwent cardiac surgery. Her symptoms improved following the surgery. Brucellosis prosthetic valve endocarditis is a rare presentation of this disease.
布鲁氏菌性人工瓣膜心内膜炎虽罕见但可能致命，是由布鲁氏菌属引起的布鲁氏菌病的一种并发症。布鲁氏菌病的症状可能不具特异性，这使得诊断颇具挑战性。骨关节受累是布鲁氏菌病最常见的并发症。除心内膜炎和中枢神经系统受累外，布鲁氏菌病的死亡率较低。诊断基于实验室检查和临床表现。血清学检测更为可取，因为培养方法可能不可靠。一名59岁女性出现胃肠道出血、发热、厌食和全身不适。她有因严重二叶式主动脉瓣狭窄接受机械瓣膜主动脉瓣置换术的病史。检查发现围绕人工瓣膜的多房性主动脉根部脓肿。她被诊断为布鲁氏菌性心内膜炎，接受了抗生素治疗并接受了心脏手术。术后她的症状有所改善。布鲁氏菌性人工瓣膜心内膜炎是这种疾病的罕见表现。
