A left ventricular assist device interfering with leadless pacemaker implantation.

Left ventricular assist devices (LVAD) produce electromagnetic interference (EMI) which can have implications when patients require cardiac implantable electronic devices. Leadless pacemakers have been successfully implanted in patients with Heartmate 2 and Heartmate 3 LVADs without evidence of EMI or device-to-device interaction. Here we report a case of a Heartmate 3 LVAD and Micra VR transcatheter pacing system interaction requiring device repositioning.
