An Adverse Electrophysiological Interaction Between an Implantable Cardioverter-Defibrillator and a Ventricular Assist Device.
Many patients with left ventricular assist devices (LVAD) have implantable cardioverter defibrillators (ICDs) as part of the management of advanced heart failure. With increasing use and coexistence of these devices in patients with advanced cardiomyopathy, adverse interactions between these devices have been recognized. We herewith describe a rare adverse interaction of electromagnetic interference (EMI) between a third-generation, continuous-flow device (The HeartWare HVAD) and an ICD which resulted in the delivery of inappropriate ICD therapies. A schematic approach for the prevention and treatment of electromagnetic interference has also been described.
