Event or Problem Description
It was reported that the right ventricular (rv) lead triggered alerts for high rate non-sustained (hrns) episodes and sensing integrity counter (sic).Hrns episodes showed true noise but pocket manipulation and isometrics were unable to reproduce the noise in clinic.Lead alerts were turned off to mitigate patient anxiety.The lead remains in use.No patient complications have been reported as a result of this event.It was further reported that additional lias occurred due to sic, hrns episodes, and lead impedance variation.In addition, there was a jump in rv pacing impedance noted.Non-sustained ventricular tachycardia (nsvt) showed oversensing that was suggestive of possible interference with the patient's cardiac contractility modulation (ccm) device which had been implanted two weeks prior to the first sensing issues.Reprogramming was performed.The implantable cardioverter defibrillator (icd) and rv lead remain in use.No patient complications have been reported as a result of this event.
Additional Manufacturer Narrative
Product event summary: the device was not returned for analysis, however, performance data collected from the device was received and analyzed.Analysis of the device memory indicated oversensing associated with the right ventricular lead.Analysis of the device memory observed noise on the electrogram waveforms.Medtronic is submitting this report to comply with fda reporting regulations under 21 cfr parts 4 and 803.This report is based upon information obtained by medtronic, which the company may not have been able to fully investigate or verify prior to the date the report was required by the fda.Medtronic has made reasonable efforts to obtain more complete information and has provided 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.In particular, this report does not constitute an admission by anyone that the product described in this report has any ¿defects¿ or has ¿malfunctioned¿.These words are included in the fda 3500a form and are fixed items for selection created by the fda to categorize the type of event solely for the purpose of regulatory reporting.Medtronic objects to the use of these words and others like them because of the lack of definition and the connotations implied by these terms.This statement should be included with any information or report disclosed to the public under the freedom of information act.Any required fields that are unpopulated are blank because the information is currently unknown or unavailable.A good faith effort will be made to obtain the applicable information relevant to the report.If information is provided in the future, a supplemental report will be issued.
