Event Description

It was reported that the right ventricular (rv) lead exhibited steadily rising thresholds that became high, and pacing impedance was noted to have been trending upwards as well but was still within range.It was suspected that this increase was related to physiologic changes with the lead/tissue interface over time rather than a lead integrity issue.Reprogramming was performed, and the lead remains in use and will be monitored. no patient complications have been reported as a result of this event.

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 trend of the right ventricular pacing lead was rising.Analysis of the device memory indicated pacing capture threshold in the right ventricle was elevated.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.
