As a consequence of the growing number of implanted transcatheter aortic valve prostheses, the increasing incidence of early and late complications of biological valves requires in several cases surgical explantation of the transcatheter valve and subsequent aortic root or surgical aortic valve replacement. In this video tutorial, we show how to avoid aortic root damage in the surgical explantation of a transcatheter aortic valve bioprosthesis in a patient with a dysfunctional transcatheter aortic valve prosthesis affected by endocarditis 15 months after implantation. The infected prosthesis and all foreign materials, concomitant to the calcified native valve, were excised en bloc in preparation for the extensive debridement of infected tissue in the abscess cavity. The defect on the aortic annulus was reconstructed using a pericardial patch, followed by a surgical valve implant.
由于植入经导管主动脉瓣假体的数量不断增加,生物瓣的早期和晚期并发症的发生率也在增加,因此在某些情况下需要对经导管瓣膜进行外科取出,并随后进行主动脉根部或外科主动脉瓣置换。在这个视频教程中,我们展示了如何在一名植入 15 个月后因心内膜炎而出现功能障碍的经导管主动脉瓣生物瓣假体患者的外科取出中避免主动脉根部损伤。感染的假体和所有外来物质,与钙化的原生瓣膜一起,整块切除,为脓肿腔内感染组织的广泛清创做准备。用心包补片重建主动脉瓣环的缺损,然后植入外科瓣膜。
