Medtronic recalls certain CRT-D devices (model DTBB1QQ) that may have reduced or no energy output during high voltage therapy, potentially affecting heart rhythm treatment.
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 specific models of implantable cardioverter defibrillators (CRT-Ds) that may not deliver proper energy during high voltage therapy. This could lead to ineffective heart rhythm treatment in patients using these devices.
The recalled devices use a specific glassed feedthrough that may cause reduced or no energy output during high voltage therapy (typically 0-12J). This could result in the device failing to treat heart rhythm issues as intended.
Patients with Medtronic CRT-D devices (model DTBB1QQ) who have been implanted with the recalled devices are affected. Those with the specific lot/serial numbers listed in the recall are at risk of reduced therapy effectiveness.
