Manufacturer Narrative
A supplemental report is being submitted for investigation completion and additional information b5.Product event summary: the ventricular assist device (vad) (b)(4) was not returned for evaluation.Two (2) controllers (b)(6) and five (5) batteries (b)(6) were returned for evaluation.No performance allegations were made against the returned controllers and batteries.Failure analysis of the returned controllers and batteries revealed that the devices passed visual inspection and functional testing.Of note, it was observed that the battery (b)(6) had exceeded the useful operating life of 500 charge and discharge cycles.This is an additional finding not related to the reported event and can be attributed to the battery reaching the end of its useful life.Review of the controller log files associated with (b)(6) revealed that the controller was not in use during the reported event date and was likely being used as a back-up controller.Log file analysis revealed that (b)(6) was the patient's primary controller, in use during the reported event.Review of the controller log files revealed associated with (b)(6) revealed four (4) controller power up events with associated pump start events logged on (b)(6) 2021 at 19:55:09, on (b)(6) 2021 at 20:20:36, and on (b)(6) 2021 at 13:31:05 and 14:09:49.No anomalies were logged prior to the losses of power.The controller was off 1 minute and 26 seconds, 11 seconds, 9 minutes and 7 seconds, and 2 minutes and 9 seconds, respectively.Log file analysis also revealed a gradual decrease in power consumption and estimated flows on (b)(6) 2021 beginning at 14:01:45, leading to parameters below normal operating range.Two (2) low flow alarms were logged on (b)(6) 2021 and four (4) low flow alarms were logged on (b)(6) 2021 between 13:32:20 and 14: 10:01.As a result, the reported low flow event was confirmed.Information received from the site indicated that, in addition to the low flow event, the patient was found lying unconscious in bed with no pulse.The emergency medical services (ems) was called and the patient was pronounced dead.An autopsy was not performed and a cause of death was not provided.Based on the available information, the device may have caused or contributed to the reported event.Per the instructions for use, death is known potential complication associated with the implantation of a vad.A possible root cause of the observed losses of power can be attributed to a disconnection of both power sources and/or to an intermittent disconnection on one or both power sources.Capa: pr00551638 is investigating controller losses of power.Based on the risk documentation, possible causes of the reported low flow event may be attributed to multiple factors including but not limited to poor vad filling, thrombus at the inflow cannula/outflow graft, and/or constriction at the outflow graft.Possible clinical factors that may have contributed to this event include the patient¿s pre-existing history and related comorbidities, the progression of their underlying disease, issues related to the therapeutic use of anticoagulant and antiplatelet medications and the patient's complex post-operative course.There are possible patient, pharmacological and procedural factors that may have contributed to this event.D1: heartware ventricular assist system - controller 2.0 d4: model#: 1420-controller/ catalog#: 1420-controller / expiration date: 30-jun-2021 / serial or lot#: (b)(6); udi#: (b)(4); d10: yes, return date:.1-dec-2021; h3: yes dev rtn to mfr?
