PO-05-047 METHODOLOGY OF VENTRICULAR SEPTAL PACING USING STYLET-DRIVEN LEAD AND THREE-DIMENSIONAL GUIDING CATHETER

Superiority of conduction system pacing is recognized and need for septal/physiological emerging. Recently, catheter-guided implantation stylet-driven lead(SDL) was introduced to clinical use. The present study carried out investigate the acute efficacy safety different strategies ventricular septal implantations SDL compared apical implantation. We retrospectively analyzed consecutive patients who underwent leads, including both initial experience implantations. paced QRS duration between 4 groups: G1(apical implantation), G2(septal with fluoroscopic guidance), G3(septal echo-guidance), G4(septal echo-guidance additional lead-body rotation). Body rotation performed purpose deep pacing. also multivariate analysis find predictors short less than 130ms during In total, 80 were analyzed. Selectra3D catheter exclusively used implant conventional screw-in leads into septum. Eight physicians (6 in-training 2 experienced) implanted all leads. number in G1,G2,G3,and G4 21,12,29,and 19, respectively. In-procedural or post-procedural dislodgement lead frequently G3/G4 G2(2% vs. 21%). 161±15,146±13,140±11,and 132±18ms, respectively.(Figure) As echo-guided cohorts (G2 G3), revealed body-rotation(OR: 5.72(95%CI: 1.46-22.4), P=0.012) experienced physician (OR:5.48(95%CI: 1.16-25.8), P=0.031) significantly associated duration. Combination echocardiographic guidance body-rotation could be effective improve procedural results after SDLs.
