Retention of semifloating electrode catheter

Area of Science:

• Cardiology
• Medical Devices

Background:

• Temporary right ventricular pacing is a common procedure for managing bradyarrhythmias.
• Prophylactic electrode insertion is indicated in specific clinical scenarios, such as bifascicular block with suspected myocardial infarction.

Observation:

• An 84-year-old male patient received a semifloating electrode for temporary right ventricular pacing.
• After six days, attempts to remove the electrode were unsuccessful.

Findings:

• The case illustrates a rare but significant complication of temporary right ventricular pacing: electrode retention.
• The inability to extract the indwelling electrode underscores the potential for mechanical complications.

Implications:

• This event highlights the importance of careful monitoring and consideration of lead management strategies.
• Physicians should be aware of the potential for electrode retention as a non-theoretical hazard in temporary pacing.
• Further research into preventative measures and extraction techniques for retained pacing electrodes may be warranted.
