A 66-year-old Australian man underwent elective replacement of a severely stenotic aortic valve with a 22-mm Medtronic-Hall valve. Six weeks later, he was readmitted with worsening dyspnea, fever, and mild anemia. Investigations confirmed pulmonary edema and moderate periprosthetic aortic regurgitation. The pulmonary edema was managed conservatively, and a second 22-mm Medtronic-Hall valve was implanted. Infective endocarditis was suspected in the aortic annulus below the orifice of the right coronary artery. A bacteriological study revealed a rare bacteria of Streptomyces species. The patient received intensive antibiotic therapy over a 6-week period of hospitalization, and the aortic regurgitation disappeared one week postoperatively.
一名66岁的澳大利亚男子接受了择期手术，用一枚22毫米的美敦力-霍尔瓣膜替换了严重狭窄的主动脉瓣。六周后，他因呼吸困难加重、发热和轻度贫血再次入院。检查证实有肺水肿和中度人工瓣膜周围主动脉瓣反流。对肺水肿进行了保守治疗，并植入了第二枚22毫米的美敦力-霍尔瓣膜。怀疑右冠状动脉开口下方的主动脉瓣环发生感染性心内膜炎。细菌学研究发现了一种罕见的链霉菌属细菌。患者在住院6周期间接受了强化抗生素治疗，术后一周主动脉瓣反流消失。
