Results from a pivotal clinical trial presented as a late-breaker at Heart Rhythm 2023 indicate that a new leadless pacemaker technology can deliver cardiac resynchronization therapy in patients who were not able to be treated with conventional CRT and epicardial leads.

Left bundle branch pacing emerges as an alternative to biventricular pacing in two late-breaking trials

The use of left bundle branch area pacing (LBBAP) is growing in electrophysiology implanted devices. Two late-breaking studies at Heart Rhythm 2023 highlight the success of LBBAP as an alternative to the standard of care using biventricular pacing.
