MAUDE Adverse Event Report: MEDTRONIC SINGAPORE OPERATIONS SPRINT QUATTRO SECURE S MRI SURESCAN; DEFIBRILLATOR, AUTOMATIC IMPLANTABLE CARDIOVERTER

Model Number 6935M62

Device Problems Signal Artifact/Noise (1036); Electromagnetic Interference (1194); Over-Sensing (1438); Low impedance (2285); Capturing Problem (2891); Impedance Problem (2950); High Capture Threshold (3266); Unstable Capture Threshold (3269)

Patient Problem No Clinical Signs, Symptoms or Conditions (4582)

Event Date 09/04/2023

Event Type  malfunction  

Event Description

It was reported that the right ventricular (rv) lead triggered lead integrity alert (lia).The rv lead showed impedances on lower side and thresholds on the higher side and observed with high rate non-sustained episodes/high sensing integrity counter (sic).The rvtip to coil impedance had been low and stable, however, in the last measurements there was a gradual increase in impedance and it was noted that rv defib coil impedance trends showed some variation but within normal values.The rv threshold has been variable and increasing over time.The rv lead is still in use.No patient complications have been reported as a result of this event.

Event Description

Additional information received noted that the physician no longer suspects faster than expected battery longevity.It was noted that the high-rate non-sustained episodes consistent of external noise / electromagnetic interference was confirmed and the cause was determined to be lead failure.The patient was hospitalized, and the threshold was tested and adjusted.The rv lead was later replaced.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 oversensing associated with the right ventricular lead.Analysis of the device memory indicated the criteria for the right ventricular lead integrity alert were met.Analysis of the device memory indicated the impedance trend of the right ventricular defibrillation coil was variable.Analysis of the device memory indicated the impedance trend of the right ventricular pacing lead was rising.Analysis of the device memory indicated the impedance trend of the right ventricular pacing lead was variable.Analysis of the device memory indicated pacing capture threshold in the right ventricle was elevated.Analysis of the device memory indicated pacing capture threshold in the right ventricle was rising.Analysis of the device memory indicated pacing capture threshold in the right ventricle was unstable.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.
