Event Description
|
It was reported that overestimation was observed on the device during follow-up.During subsequent follow-up, the device was found to have reached its elective replacement indicator (eri).Slow interrogation was observed on the device.The device was explanted and replaced to resolve the event.During explant, there was difficulty removing the right ventricular (rv) lead from the header of the device.The device was successfully explanted and replaced to resolve the event.The patient was stable following the procedure and there were no adverse consequences.

Manufacturer Narrative
|
The longevity estimation anomaly near elective replacement indicator (eri) was confirmed by reviewing the data in the session records and device image data.The longevity overestimation was determined to be due to an estimation inaccuracy in the programmer remaining longevity calculation.An enhancement request was also submitted by the software engineering team to resolve the issue in the future.The reported event of difficulty removing the right ventricular (rv) lead from the header was confirmed.Analysis found the returned device had the original header design with tighter tolerances for this design.Excess force and/manipulation maybe required to insert the leads into the connectors, and almost equal or greater forces would then be needed to remove the leads, which likely occurred in the field, during the replacement surgery.The reported event of no audible alert for end of service (eos) was confirmed.The device is not designed to have an audible eos patient notifier alert.
