An 81-year-old male presented with severe, symptomatic bioprosthetic surgical aortic valve dysfunction. He was considered high-risk for reoperation and cardiovascular imaging determined him to be a very high-risk for coronary occlusion with valve-in-valve TAVR. This is the first reported case of valve-in-valve TAVR facilitated by percutaneous transapical UNICORN procedure.
一名81岁男性出现严重的、有症状的生物人工心脏主动脉瓣功能障碍。他被认为再次手术风险高，心血管成像显示他进行经导管主动脉瓣置换术（TAVR）瓣膜中置瓣膜手术时冠状动脉闭塞风险极高。这是首例经皮经尖UNICORN手术辅助的瓣膜中置瓣膜TAVR病例报告。
