Unprecedented Complication of Left Bundle Branch Pacing

Key Result

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.

Key Points

• The aim is to explore the rare complications associated with conduction system pacing, specifically focusing on mechanical issues.
• Observation of pacing parameters during lead manipulation.
• Assessment of impedance changes to identify potential complications.
• Monitoring resistance during procedures to detect tissue entrapment.
• Identified mechanical complications such as septal injury and mitral chordal entrapment.
• Demonstrated that abrupt changes in impedance can indicate possible structural damage.
• Highlighting the importance of monitoring pacing parameters for early recognition of complications.
