Sprint Fidelis implantable cardioverter defibrillator (ICD) lead - risk of inappropriate shocks
(Medtronic) use of Sprint Fidelis ICD lead could create risk of inappropriate shocks and loss of therapy with model numbers 6930, 6931, 6948 and 6949. (MDA/2011/051)
Device
Implantable cardioverter defibrillator (ICD) lead.
Sprint Fidelis, model numbers: 6930, 6931, 6948 and 6949.
Manufactured by Medtronic.
Problem
Risk of inappropriate shocks and loss of therapy.
Increased risk that the high voltage conductor will fracture if the pace-sense conductor has previously fractured in the same lead.
In March 2009 Medtronic issued a (42Kb) advising clinicians that one option for dealing with this problem was to implant a new pace-sense lead while maintaining the use of the high voltage conductor.
However, Medtronic estimates that the survival for the Sprint Fidelis high voltage conductor is 77.7% at 21 months if a pace-sense conductor fracture has previously occurred. Therefore, Medtronic no longer recommends this course of action and has issued another (586Kb). All other patient management recommendations in the March 2009 FSN remain unchanged.
Action
Identify patients where:
-
the pace-sense conductor has fractured,
-
a new pace-sense lead has been inserted and
-
the high voltage conductor remains in use.
For these patients, consider the need to implant a new high voltage conductor at elective device change, taking into account the age and clinical circumstances of the patient.
If these patients are at high risk of sudden cardiac death in the event of high voltage conductor failure, then consider elective lead replacement before device change.
Where a new conductor fracture occurs, implant a new high voltage lead. Where a lead is functioning normally, continue with existing patient management recommendations and use of Medtronic Lead Integrity Alert (LIA). This should be done taking into account the recent update in long term lead survival data presented in the (586Kb).
