Left bundle branch pacing can cause rare mechanical complications like septal injury and mitral chordal entrapment, which may be prevented by monitoring impedance changes during lead manipulation.
Monitoring pacing parameters such as abrupt impedance changes or resistance during lead manipulation may aid in early recognition of tissue entrapment and prevent structural damage during left bundle branch pacing.
Although rare, conduction system pacing can result in mechanical complications such as septal injury and mitral chordal entrapment. Monitoring of pacing parameters, including abrupt impedance changes or resistance during lead manipulation, may aid in early recognition of tissue entrapment and prevent structural damage.
Kumar et al. (2026) studied this question. Left bundle branch pacing can cause rare mechanical complications like septal injury and mitral chordal entrapment, which may be prevented by monitoring impedance changes during lead manipulation.
