Additional Manufacturer Narrative
Continuation of d10: dtpb2d1 crtd implanted: (b)(6) 2023; medtronic submits this report to comply with fda regulations 21 cfr parts 4 and 803.Medtronic has made reasonable efforts to provide as much relevant information as is available to the company as of the submission date of this report.This report does not constitute an admission or a conclusion by fda, medtronic, or its employees that the device, medtronic, or its employee caused or contributed to the event described in the report.Any required fields that are unpopulated are blank because the information is currently unknown or unavailable.Medtronic will submit a supplemental report if additional relevant information becomes known.
Event or Problem Description
It was reported that the right ventricular (rv) lead exhibited high, undefined measurements for pacing, defibrillation and superior vena cava (svc) impedances.The lv lead also exhibited high, undefined pacing impedances.The rv lead also exhibited oversensing ofnoise and it was suspected that a rv coil fracture had occurred.The rv lead and lv lead remain in use.No patient complications have been reported as a result of this event.
Event or Problem Description
It was later reported that the lv lead was programmed off.
Additional Manufacturer Narrative
Product event summary: the lead was not returned for analysis.However, performance data collected from the device was received and analyzed.Analysis of the device memory indicated the impedance of the left ventricular pacing lead was beyond the expected upper range.Medtronic submits this report to comply with fda regulations 21 cfr parts 4 and 803.Medtronic has made reasonable efforts to provide as much relevant information as is available to the company as of the submission date of this report.This report does not constitute an admission or a conclusion by fda, medtronic, or its employees that the device, medtronic, or its employee caused or contributed to the event described in the report.Any required fields that are unpopulated are blank because the information is currently unknown or unavailable.Medtronic will submit a supplemental report if additional relevant information becomes known.

Event or Problem Description
It was further reported that the rv lead also exhibited high thresholds, and was explanted and replaced.During the replacement procedure, the lv was tested, and it was determined that the high lv impedances had been due to the programmed lv tip to rv coil pacing vector.After being connected to the new device, the lead measurements were all within normal limits.The lv lead was reactivated and remains in use.No patient complications have been reported as a result of this event.
