VF zone ATP may not be automatically enabled and may require manual programming
ANZCDACC Advisory Notice 6 December 2020
Device: Medtronic Cobalt™ and Crome™ ICDs and CRT-Ds
Advisory grade TGA: Urgent Product Defect Correction
ANZDACC Advisory Grade: Routine
Description:
The of Ventricular fibrillation anti-tachycardia pacing (VF- ATP) parameter in these devices may not be automatically enabled and may require manual programming and as such may inadvertently be set to off.
Number of devices affected in Australia and New Zealand:
Australia: and New Zealand: TBA
Presentation:
Patient may present with high voltage therapies which were previously treated with ATP
Rate of occurrence:
1 incidence out of 3,237 devices implanted worldwide related to this advisory issue. No serious adverse events have been reported. These devices will deliver all programmed high-voltage therapies as programmed, regardless of the VF ATP parameter setting being off. The issue is risk for a high-voltage therapy to be applied for a Fast VT arrhythmia in the VF detection zone, which could have been treated with ATP during Charging.
Recommendation:
Confirm the appropriate selection has been programmed for the VF ATP parameter at implant.
At routine follow-up, confirm that the VF ATP parameter is programmed to the desired setting for each patient.
The ANZCDACC encourage you to report any adverse event or near (potential) adverse event associated with the use of a medical device including any abnormal CIED or lead function. We encourage reporting to ANZCDACC directly via the Committee chair Dr Paul Gould [email protected] and to the following regulators.
