Question:
What are the risks of the procedure of transvenous (traditional) Left Bundle Branch Area Pacing (LBBAP)?
Answer:
The procedure of transvenous Left Bundle Branch Area Pacing (LBBAP), while effective in restoring physiologic pacing, does involve certain risks similar to other transvenous pacing techniques. The main risks include:
- Lead-related complications: Risk of lead dislodgement, fracture, or failure to capture the conduction system.
- Perforation: Potential risk of septal or myocardial perforation during lead placement.
- Infection: As with any implanted device, there is a risk of infection at the pocket or lead site.
- Vascular injury: Possibility of venous thrombosis, hematoma, or vessel trauma at access site.
- Arrhythmias: Manipulation of the lead within the conduction system may provoke atrial or ventricular arrhythmias.
- Long-term risks: Lead extraction in the future may be technically challenging due to deep septal lead placement.
Overall, LBBAP is considered a safe and increasingly adopted alternative to His-bundle pacing, with a generally favorable risk-benefit profile when performed by experienced operators.
