We report on a man with bioprosthetic mitral valve perforation who presented late after transcatheter aortic valve replacement with a balloon-expandable transcatheter heart valve (THV). The protrusion of the commissural strut of the bioprosthetic mitral valve coupled with the low implanted THV resulted in repetitive trauma leading to rupture of a mitral leaflet. Potential preventive strategies are discussed. This case illustrates the importance of preprocedural imaging screening and cautious THV deployment in patients with a bioprosthetic mitral valve.
我们报告了一例生物瓣二尖瓣穿孔的男性患者，该患者在经导管主动脉瓣置换术后较晚出现症状，所置换的是球囊扩张式经导管心脏瓣膜（THV）。生物瓣二尖瓣连合支柱的突出加上THV植入位置较低，导致反复创伤，进而引起二尖瓣叶破裂。文中讨论了潜在的预防策略。该病例说明了术前影像筛查以及在生物瓣二尖瓣患者中谨慎部署THV的重要性。
