Subcutaneous implantable cardioverter defibrillator (S-ICD) electrode displacement can go undetected. Comparing S-ICD electrograms during follow-up can prevent this issue.

Area of Science:

  • Cardiology
  • Medical Devices
  • Electrophysiology

Background:

  • Secondary prevention with subcutaneous implantable cardioverter defibrillators (S-ICDs) is crucial for managing sudden cardiac death risk.
  • Ensuring the proper function and placement of S-ICD electrodes is vital for device efficacy.

Observation:

  • Two cases of S-ICD implantation experienced undetected electrode displacement.
  • Displacement was identified through a routine chest X-ray and an unmonitored event via remote monitoring.
  • Neither patient's initial presentation immediately indicated the electrode displacement.

Findings:

  • Comparing current subcutaneous electrograms (S-ECGs) with those recorded at the time of S-ICD implantation can reveal electrode displacement.
  • This comparison is a simple yet effective strategy for early detection of displacement.

  • Undetected displacement poses a risk to patient safety and device performance.

    • Implications:

    • Routine comparison of S-ECGs during follow-up appointments is recommended for all S-ICD patients.
    • Implementing this strategy can improve patient outcomes and device reliability.
    • This highlights the importance of vigilant monitoring and standardized follow-up protocols for S-ICD systems.
