Which of the following is a potential risk associated with LBBAP?

The potential risk associated with Left Bundle Branch Area Pacing (LBBAP) that identifies RBB injury as a concern is rooted in the anatomical and physiological implications of the pacing technique. LBBAP targets the left bundle branch to achieve effective ventricular pacing, but in doing so, there is a risk of inadvertently affecting the right bundle branch or surrounding tissues.

When pacing occurs in the left bundle branch area, if the lead is placed too close to the right bundle branch, the electrical pathways may be disrupted. This can lead to changes in conduction through the right bundle branch, potentially resulting in right bundle branch block (RBB) injury. Such an injury can manifest as conduction abnormalities, which would typically result in a right bundle branch block pattern on the electrocardiogram.

The context for this risk emphasizes the technical skill required in LBBAP placement and careful consideration of the lead positioning, to minimize the potential for RBB injury while achieving the desired electrical pacing outcome. This highlights the need for practitioners to be aware of the anatomical relationships within the heart and the electrical conduction pathways when performing such procedures.
