A Proposed Anatomical-Fluoroscopic Workflow to Identify the Optimal Split Line for Leaflet Modification in Redo-TAVR
Listen to this summary
The authors aim to refine the optimal leaflet modification strategy for redo transcatheter aortic valve replacement (TAVR) by clarifying the anatomical relationships between valve leaflets and surrounding structures. They propose a systematic, imaging-guided workflow that identifies modifiable leaflet regions and suggests specific split lines to avoid coronary obstruction, based on preprocedural computed tomography. Further studies are planned to evaluate the feasibility and effectiveness of this proposed approach.
