I attended a Medtronics seminar at the local hospital yesterday evening. The meeting was a result of the re-call notice on four models of the Sprint Fidelis leads.
The company and the docs all admit that there could be a problem with the leads cracking, but there doesnt seem to be anything really conclusive at this time. The recall is reported completely voluntary.
For those in attendance who were interested, they re-set the sensitivity of our ICD so that the audible will sound if there is a problem - or potential problem.
The general recommendation seems to be close monitoring. There are no general plans to replace the leads leads at this time, as this could create more problems.
If anything, they would cap the cracked leads and put in new leads.
