MAUDE Adverse Event Report: BIOTRONIK SE & CO. KG SAFIO S 53; PACING LEAD

Model Number	370945
Medical Device Problem Codes	Over-Sensing (1438); Device Sensing Problem (2917); Impedance Problem (2950)
Health Effect - Clinical Code	No Clinical Signs, Symptoms or Conditions (4582)
Date of Event	09/21/2021
Type of Reportable Event	Malfunction
Event or Problem Description
After an implantation period of approximately 88 months, it was reported that oversensing in the atrial channel, suddenly increasing pacing impedance and loss of sensing were detected.The lead is now inactive.
Additional Manufacturer Narrative
As of today, the medical device is not available for analysis, therefore the device itself could not be investigated.The analysis is thus based on the inspection of the manufacturing documents of the device as well as on the provided data.Prior to the analysis of the device, the quality documents accompanying the manufacturing process for this device were re-investigated.All production steps were performed accordingly, and in particular the final acceptance test proved the device functions to be as specified.The analysis of the provided trend data, acquired between 7-feb-2021 and 4-oct-2021 recorded the sudden increase of the pacing impedance from approximately 550ohms to 3000ohms and a varying sensing amplitude between 5mv and 7mv with a sudden drop to 2mv.The analysis of the provided iegm episodes revealed artifacts on the atrial channel, which led to the reported oversensing.In spite of the available information, no conclusion can be drawn regarding the root cause of the clinical observation.An analysis of the lead itself would be necessary to determine the root cause.Should additional information or the device itself become available for analysis, the investigation will be updated.
