Transcatheter mitral valve-in-valve replacement (TMViVR) in degenerated bioprostheses or valvular rings shows promise as an alternative to surgical MVR in selected high-risk patients. However, these procedures are particularly challenging given the complex anatomy of the mitral valve apparatus and the surrounding structures, potentially causing LV outflow tract obstruction (LVOTO). Preprocedural planning with virtual implantation and planimetric estimation of the neo-LVOT at end-systole is crucial for improving procedural results. In this case, we also include a dynamic evaluation of the neo-LVOT and implement virtual reality imaging for immersive assessment of the implanted valve.
经导管二尖瓣瓣中瓣置换术（TMViVR）用于退化的生物假体或瓣膜环，在特定高危患者中有望成为外科二尖瓣置换术（MVR）的替代方案。然而，鉴于二尖瓣装置和周围结构的复杂解剖结构，这些手术极具挑战性，可能导致左心室流出道梗阻（LVOTO）。术前通过虚拟植入进行规划并在收缩末期对新左心室流出道（neo-LVOT）进行平面测量评估，对于改善手术效果至关重要。在本病例中，我们还对neo-LVOT进行了动态评估，并采用虚拟现实成像对植入瓣膜进行沉浸式评估。
