Structural valve deterioration is a well-studied phenomenon in bioprosthetic heart valves. Conversely, structural valve deterioration after transcatheter aortic valve implantation is not as well-elucidated. Therefore, late surgical explantation after transcatheter aortic valve implantation is an infrequent procedure, and thus, surgical findings and management of such cases remain unclear, particularly in patients previously labelled as 'inoperable' or at 'high risk'. Herein, we report the case of a late surgical explantation of a transcatheter heart valve (THV) 7 years after its implantation in a patient with a porcelain aorta and periprosthetic regurgitation.
结构性瓣膜退化是生物瓣心脏瓣膜中研究得很好的现象。相反，经导管主动脉瓣植入术后的结构性瓣膜退化则没有那么清楚。因此，经导管主动脉瓣植入术后的晚期外科瓣膜取出是一种不常见的手术，因此，对于此类病例的手术发现和处理仍然不清楚，特别是在以前被标记为“不能手术”或“高危”的患者中。在此，我们报告了一例在植入经导管心脏瓣膜（THV） 7 年后，因瓷化主动脉和瓣周反流而行外科瓣膜取出的病例。
