PO-02-029 USE OF AN ACTIVE FIXATION, STYLET DRIVEN LEAD DURING LEFT BUNDLE BRANCH AREA PACING

Left bundle branch area pacing (LBBAP) is increasingly being used. Few cases have been reported using a fixed helix, stylet driven lead (Fineline II Sterox EZ, Boston Scientific). Moreover, given the lead’s design, in which electrode not located screw but rather at base of screw, concerns about higher risk inadvertent perforation exist. To describe procedural characteristics LBBAP helix lead. Consecutive patients undergoing Fineline were included. The last consecutive with different leads used as control 2:1 ratio. Before implant, tip was inserted 30 seconds saline to dissolve polyethylene glycol cover. commercially available sheath (SSPC2 or SSPC3, Scientific) and standard technique. After left capture obtained, fully into pushed determine septal perforation. first primary endpoint success. second procedure related complications, including Secondary endpoints included time fluoroscopy time. Between October 2022 November 2022, total 54 (mean age 70.6±11 years, 29.6% female) underwent LBBAP. In 18 There no significant differences baseline characteristics. Procedural success achieved 96% patients, between groups. Patients group had trend towards shorter post QRS duration (113.1±18.9 vs. 125.3±20.6, p = 0.05). No found. can be high percentage Ez, without any Current regarding theoretical risks associated this are unjustified. Interestingly, (possibly location closer midseptum) observed when leads.
