: The mismatch between tricuspid valve (TV) leaflet length and annulus dilation, assessed with the septal-lateral leaflet-to-annulus index (SL-LAI), predicts residual tricuspid regurgitation (TR) following tricuspid transcatheter edge-to-edge-repair (T-TEER). When posterior leaflet grasping is required, the anterior-posterior leaflet-to-annulus index (AP-LAI) may offer additional information.
