Key result
A novel method combining a nine-grid fluoroscopy system with intracardiac echocardiogram for left bundle branch area pacing achieved an acute success rate of 86.7%.
Why the study?
Although left bundle branch area pacing is feasible, the optimal right ventricular implantation site remains elusive, prompting evaluation of a novel method to guide lead implantation.
Does a combination of a nine-grid system on fluoroscopy and intracardiac echocardiogram improve the feasibility of left bundle branch area pacing in patients with pacing indications?

Does a combination of a nine-grid system on fluoroscopy and intracardiac echocardiogram improve the feasibility of left bundle branch area pacing in patients with pacing indications?
A novel method combining a nine-grid fluoroscopic system and intracardiac echocardiography is feasible and safe for guiding left bundle branch area pacing to the posteromedial basal septum.
Feng et al. (2020) conducted an observational in Indications for pacing therapy (n=15). Left bundle branch area pacing (LBBAP) guided by intracardiac echocardiogram (ICE) and a nine-grid system was evaluated on Acute success rate of LBBAP lead implantation. A novel method combining a nine-grid fluoroscopy system with intracardiac echocardiogram for left bundle branch area pacing achieved an acute success rate of 86.7%.
