Trial Outcomes & Findings for LBBAP Data Collection Registry (NCT NCT05887323)

NCT ID: NCT05887323

Last Updated: 2024-10-08

Results Overview

The primary safety endpoint evaluates a LBBAP lead related SADE rate which is an appropriate measure for safety and consistent with the primary safety endpoints used for evaluating performance of the transvenous right ventricular lead.

Recruitment status

Measure
Left Bundle Branch Area Implant
Data included in this LBBAP data collection registry will be from subjects followed for 6 months (± 3 months) after attempted implant of LBBAP location. Data will be collected from previously occurring visits at pre-implant (baseline, required), implant (required), 6 months (±3 months, required), and 12 months (-2, +4months, optional). Implantation of the Tendril 2088 lead in the LBBA: Conduction system pacing is achieved by delivering a pacing stimulus to the Left Bundle Branch area of the heart with Abbott's Tendril 2088 lead.
