Lead-to-Port Reversal Mimicking Loss of Cardiac Resynchronization Therapy After CRT-D Generator Replacement

Key Result

Systematic pacing maneuvers and electrocardiogram interpretation rapidly differentiate lead-to-port reversal from mechanical lead failure, preventing inappropriate lead revision.

Key Points

• The aim is to illustrate how to distinguish between electrical misconnection and mechanical lead failure in cardiac devices.
• Performed systematic pacing maneuvers
• Conducted thorough electrocardiogram interpretation
• Analyzed data to identify the nature of the issue
• Rapid differentiation between misconnection and mechanical failure was achieved
• Prevented misdiagnosis of lead issues
• Avoided inappropriate lead revision procedures
