Redo MitraClip Intervention – The Importance of Comprehensive Imaging Evaluation

To understand and highlight the mechanisms of recurrent MR after prior transcatheter mitral valve edge-to-edge repair.To describe the comprehensive imaging evaluation of recurrent MR and guide redo intervention.To demonstrate the importance of advanced 3D TEE techniques in the pre-procedural imaging and intraprocedural guidance.To establish a helpful guide in the imaging assessment of such cases. To understand and highlight the mechanisms of recurrent MR after prior transcatheter mitral valve edge-to-edge repair. To describe the comprehensive imaging evaluation of recurrent MR and guide redo intervention. To demonstrate the importance of advanced 3D TEE techniques in the pre-procedural imaging and intraprocedural guidance. To establish a helpful guide in the imaging assessment of such cases. MR: Mitral regurgitation; TEE: Transesophageal echocardiography; MPR: multiplanar reconstruction; 3D: 3-dimensional; MS: Mitral stenosis; SLD: Single leaflet detachment; MVA: Mitral valve area; TEER: Transcatheter edge-to-edge repair本数据集旨在阐明并凸显经导管二尖瓣缘对缘修复术（Transcatheter edge-to-edge repair, TEER）术后复发性二尖瓣反流（Mitral regurgitation, MR）的发病机制；全面描述复发性MR的影像学评估方案，并为二次介入治疗提供指导；论证先进三维经食管超声心动图（Transesophageal echocardiography, TEE）技术在术前影像学评估与术中操作引导中的重要价值；为该类病例的影像学评估建立实用指导指南。 本数据集旨在阐明并凸显经导管二尖瓣缘对缘修复术后复发性MR的发病机制；全面描述复发性MR的影像学评估方案，并为二次介入治疗提供指导；论证先进三维TEE技术在术前影像学评估与术中操作引导中的重要价值；为该类病例的影像学评估建立实用指导指南。 术语说明： MR：二尖瓣反流（Mitral regurgitation） TEE：经食管超声心动图（Transesophageal echocardiography） MPR：多平面重建（multiplanar reconstruction） 3D：三维（3-dimensional） MS：二尖瓣狭窄（Mitral stenosis） SLD：单瓣叶脱离（Single leaflet detachment） MVA：二尖瓣瓣口面积（Mitral valve area） TEER：经导管二尖瓣缘对缘修复术（Transcatheter edge-to-edge repair）
