Same-Day Discharge After Left Bundle Area Pacing.

Background: Left bundle area pacing (LBAP) has emerged as an area that appears to be an attractive alternative to other forms of physiological pacing owing to its ease and favorable pacing parameters. Same-day discharge after conventional pacemakers, implantable cardioverter defibrillators, and more recently leadless pacemakers have become routine, especially after the COVID-19 pandemic. With the advent of LBAP, the safety and feasibility of same-day discharge remain unclear.

Methods: This is a retrospective, observational case series of consecutive, sequential patients undergoing LBAP at Baystate Medical Center, an academic teaching hospital. We included all patients who underwent LBAP and were discharged on the same day of procedure completion. Safety parameters included any procedure-related complications including pneumothorax, cardiac tamponade, septal perforation, and lead dislodgement. Pacemaker parameters included pacing threshold, R-wave amplitude, and lead impedance pre-discharge the following day of implantation and up to 6 months of follow-up.

Results: A total of 11 patients were included in our analysis, the average age was 70.3 ± 6.74 years. The most common indication for pacemaker insertion was AV block (73%). No complications were seen in any of the patients. The average time between the procedure and discharge was 5.6 hours. Pacemaker and lead parameters were stable after 6 months of follow-up.

Conclusions: In this case series, we find that same-day discharge after LBAP for any indication is a safe and feasible option. As this mode of pacing becomes increasingly more common, larger prospective studies evaluating the safety and feasibility of early discharge after LBAP will be needed.
