We report our experience with aortic valve replacement in a patient with severe aortic stenosis who had self-reported allergies to multiple metals. The patient was a 74-year-old man. He developed palmoplantar pustulosis after using a dental prosthesis, and a patch test revealed reactions to several metals; therefore, he was diagnosed with systemic metal allergy. His condition progressed to severe aortic stenosis, and bioprosthetic aortic valve replacement was planned. The Avalus valve (Medtronic, Minneapolis, MN, USA) was selected for aortic valve replacement, since the patient reported having allergies to several metals. While most devices used in cardiac surgery contain some amount of metal, the Avalus bioprosthetic valve does not contain metal in the stent and has been extremely useful for aortic valve replacement in patients with suspected metal allergies.

我们报告了一位自述对多种金属过敏的严重主动脉瓣狭窄患者的主动脉瓣置换术的经验。患者是一名74岁的男性。使用假牙后，他患上了掌跖脓疱病，斑贴试验显示对几种金属有反应；因此，他被诊断患有全身金属过敏。他的病情发展为严重主动脉瓣狭窄，并计划进行生物主动脉瓣置换术。由于患者报告对多种金属过敏，因此选择 Avalus 瓣膜（美敦力公司，明尼苏达州明尼阿波利斯市，美国）进行主动脉瓣置换术。虽然心脏手术中使用的大多数装置都含有一定量的金属，但 Avalus 生物瓣膜支架中不含金属，对于疑似金属过敏的患者进行主动脉瓣置换术非常有用。
