Event Description
|
It was reported that the patient implanted with this subcutaneous implantable cardioverter defibrillator (s-icd) system received an appropriate shock for ventricular fibrillation (vf).Upon device interrogation, a red warning screen was displayed on the programmer.It was noted the shock impedance measurement for the delivered shock was low, out-of-range, at 5 ohms.A review of all sense vectors showed no signals.Error codes ct (charge time out) and lt (long charge time) were observed.Technical services discussed replacement of the device and electrode.The patient was hospitalized, and the s-icd system was explanted and replaced six days later.It was noted there was difficulty extracting the electrode via the xiphoid incision, and a surgeon was called in to assist.Subsequently, the electrode was removed successfully and a new s-icd system was implanted.No additional adverse patient effects were reported.The explanted products were returned for analysis.

Patient code 3191 captures the reportable event of surgery.The explanted electrode was returned and is undergoing laboratory analysis.This report will be updated when analysis is complete.The returned electrode was thoroughly inspected and analyzed.Resistance tests were completed to assess electrical performance and inner insulation integrity.Measurements throughout these tests were within normal limits.Microscopic inspections of the terminal pin assembly and electrode body found no anomalies.Laboratory analysis did not identify any electrode characteristics that would have caused or contributed to the reported clinical observations.
