The extravascular implantable cardioverter-defibrillator (EV-ICD) was developed to overcome complications associated with transvenous leads while being able to deliver anti-tachycardia pacing (ATP). The lead is implanted in the substernal space, which makes extraction a cautious procedure. We present a case of a 51-year-old women with a successful EV-ICD extraction after a lead dwell time of 4 years, which is the longest reported. The EV-ICD lead was extracted using simple traction after the removal of all adhesions at the xiphoidal site around the lead. We advise to only use extraction tools if the initial attempt is not successful and if no adhesions at the caudal part of the lead are visible anymore, as these tools could also damage the surrounding tissue and the lead.

Introduction: Substernal extravascular defibrillators (EV ICDs) have been shown to be effective and safe for patients at risk of sudden cardiac death, however, there is little evidence around the safety of extracting chronic devices.

Methods And Results: We present a 50-year-old patient in whom a Medtronic EV ICD system was successfully removed without specialist extraction tools, 186 weeks after implantation, by an operator experienced in transvenous lead extraction but without formal training in EVICD implantation.

Conclusion: The successful extraction of an EV ICD system is possible without specialised tools at least 3.

Article Synopsis
  • - A 52-year-old man was diagnosed with malignant mitral valve prolapse syndrome and initially had surgery to repair his mitral valve.
  • - Four years later, he needed an implantable cardioverter-defibrillator (ICD) to manage his condition.
  • - He opted for a substernal ICD, which was successfully implanted with no complications, showing good electrical performance.
