Medtronic recalls CRT-D DTBA1QQ VIVA QUAD XT IS4/DF4 US models with specific serial numbers due to rare risk of reduced or no energy output during high voltage therapy. Affected devices may require replacement.
There is a rare potential for reduced- or no-energy output during high voltage (HV) therapy (typically 0-12J) in implantable cardioverter defibrillators (ICDs) and cardiac resynchronization therapy defibrillators (CRT-Ds) manufactured with a specific (glassed) feedthrough, including currently available ICDs and CRT-Ds.
Medtronic is recalling certain CRT-D (cardiac resynchronization therapy defibrillators) models that have a rare potential for reduced or no energy output during high voltage therapy. This could affect the device's ability to properly treat heart conditions.
The device uses a specific type of glassed feedthrough that can occasionally fail to deliver proper energy during high voltage therapy (0-12 joules). This rare issue may cause the device to not function correctly when needed for heart treatment.
