When you’re referring a patient who is indicated for an ICD, determine if he or she is a good candidate for S-ICD: the first and only FDA-approved subcutaneous implantable defibrillator that leaves the vasculature untouched and avoids the risks associated with transvenous leads.

What is an S-ICD?

A new generation of ICD therapy, an S-ICD:

  • Is implanted just underneath the skin on the left side of the chest next to the rib cage
  • Analyzes heart rhythm using a subcutaneous electrode to effectively sense, discriminate, and convert VT/VF1
  • Leaves the heart and blood vessels untouched and intact

How Do S-ICDs Compare to TV-ICDs?

S-ICDs are designed to allow self-termination of non-sustained tachyarrhythmias.

  • The rate of inappropriate therapy for S-ICDs is consistent with TV-ICDs2, 3
  • S-ICDs provide effective detection and conversion of induced and spontaneous VT/VF episodes
  • S-ICDs offer effective discrimination of AF and SVT from VT/VF4
  • S-ICDs have low rates of significant clinical complications2,3

Benefits of an S-ICD


  • Eliminates the potential for vascular injury
  • Reduces the potential for infection
  • Preserves venous access and avoids potential complications associated with endovascular lead implantation or extraction
  • Requires few or no upper-body restrictions and few or no athletic restrictions
  • Requires less-invasive procedures for battery replacement

Referring an ICD-Indicated Patient? Think S-ICD First.

Because it leaves the heart untouched and requires few or no upper-body restrictions and few or no athletic restrictions, S-ICD may be a particularly good option for your patients who are 70 and younger, are active, or are hesitant to receive a device.

Device choice should be based on shared decision-making between HCP and patient.

SC ECG screening is mandatory to evaluate suitability of sensing vectors for the S-ICD.

* Extended Life (EL) TV-ICD models should be prioritized to minimize risk of clinical complications related to device replacement.
** VR-ICD option can be considered if the patient is NOT expected to survive his device.
