Subcutaneous Implantable Cardioverter-Defibrillator Shocks After Left Ventricular Assist Device Implantation
Key result
Implantation of a continuous-flow left ventricular assist device in a patient with a subcutaneous ICD resulted in 31 inappropriate shocks due to electromagnetic interference and oversensing.

Implication
May prompt S-ICD deactivation pre-LVAD; single case leaves open optimal perioperative protocols.

Population
A 42-year-old man with nonischemic cardiomyopathy and advanced heart failure who received a subcutaneous ICD followed by a left ventricular assist device.
E
Exposure
Subcutaneous implantable cardioverter-defibrillator (S-ICD) followed by continuous-flow left ventricular assist device (LVAD) implantation
O
Outcome
Inappropriate S-ICD shockssafety
LVAD implantation in a patient with an S-ICD can cause severe electromagnetic interference and inappropriate shocks, highlighting the need to deactivate antitachycardia therapy before surgery and carefully evaluate sensing vectors postoperatively.
Limitations
- Sparse and inconsistent data about the combination of S-ICDs and LVADs.
Cite This Study
Pfeffer et al. (2016) conducted a case report in Nonischemic cardiomyopathy and advanced heart failure (n=1). Left ventricular assist device (LVAD) implantation was evaluated on Inappropriate S-ICD shocks. Implantation of a continuous-flow left ventricular assist device in a patient with a subcutaneous ICD resulted in 31 inappropriate shocks due to electromagnetic interference and oversensing.
