Device-device interaction between cardiac implantable electronic devices and continuous-flow left ventricular assist...

Area of Science:

• Biomedical Engineering
• Cardiology
• Medical Devices

Background:

• Left ventricular assist devices (LVADs) utilize magnetic levitation for reduced friction and blood damage.
• Electromagnetic fields from LVADs can cause electromagnetic interference (EMI).
• Approximately 80% of LVAD patients also have a cardiac implantable electronic device (CIED), often an implantable cardioverter-defibrillator (ICD).

Purpose of the Study:

• To describe how LVAD-generated EMI impacts CIED functionality.
• To provide management options for EMI-related CIED issues.
• To offer manufacturer-specific guidance for various CIEDs.

Main Methods:

• Review of reported device-device interactions between LVADs and CIEDs.
• Analysis of EMI effects on different types of CIEDs.
• Compilation of management strategies and manufacturer information.

Main Results:

• Reported interactions include inappropriate shocks, telemetry issues, and battery depletion.
• EMI can lead to CIED undersensing and other malfunctions.
• Additional procedures are often required to address these interactions.

Conclusions:

• EMI from LVADs poses a significant risk to CIED function.
• Preventable or avoidable CIED malfunctions can occur due to EMI.
• Implementing appropriate management strategies is crucial for patient safety and device efficacy.
