NHLBI Transmural Electrosurgery LeafLet Traversal And Laceration Evaluation (TELLTALE) BASILICA-TAVR Trial

The TELLTALE BASILICA procedure has five steps: (1) engagement of the target leaflet with a guiding catheter; (2) electrosurgical leaflet traversal with the TELLTALE guidewire, (3) preparation and positioning of the TELLTALE guidewire electrosurgical leaflet laceration surface; (4) electrosurgical leaflet laceration with the TELLTALE guidewire, immediately followed by (5) TAVR. These are all guided by fluoroscopy, with adjunctive echocardiography as needed.
