Pacing Characteristics of a Conventional Bipolar

Sponsor: Chang Gung Memorial Hospital

Summary

Study Title: Pacing characteristics of a conventional bipolar, active fixation pacing lead for left bundle branch area pacing in patients with symptomatic bradycardia Study Objectives: To characterize an approach for left bundle branch area pacing (LBBAP) in patients with bradycardia indications for pacing and to assess implant success rate, safety, and long-term stability with a conventional bipolar, active fixation pacing lead. Methodology: Open-label, prospective, multi-center, non-randomized, single-arm study Study Endpoints: Primary Endpoint: • Implant success rate Secondary Endpoints: * Intra-operative procedure time and fluoroscopic exposure time * Intra-operative intracardiac electrogram (EGM) changes: paced QRS duration, stimulus to left ventricular (LV) activation time, and LBB potential * Post-operative imaging data: posteroanterior, left anterior oblique 30O, right anterior oblique 30O, Left lateral views * Serial paced 12-lead electrocardiogram (ECG) and intracardiac EGM changes: QRS duration (QRSd), pacing-QRS interval, and new atrial fibrillation (AF) * Serial echocardiography changes: left ventricular ejection fraction (LVEF), left atrial (LA) and LV chamber size, and global longitudinal strain (GLS) of tissue Doppler imaging * Serial changes of pacing parameters: capture threshold, impedance, and sensing amplitude for both atrial and ventricular Solia S leads * Safety: Immediate (\< 24 hours), in-hospital, and chronic (12 months) adverse events
