Manufacturer Narrative

The pump (b)(4) was not returned for evaluation.The reported "low flow" event was confirmed via log file analysis which revealed a decrease power consumption beginning on (b)(6) 2017 and 17 low flow alarms logged since (b)(6) 2017.There is no evidence to suggest that a device malfunction caused or contributed to the reported event.Based on the risk documentation, possible causes of the reported low flow event may be attributed to multiple factors including but not limited to thrombus at the inflow cannula, constriction at the outflow graft, poor vad filling.The device remains implanted in the patient and is thus not available for return to the manufacturer.With a review of the available information there is no evidence to indicate any device malfunctions or performance issues that would impact the reported events.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.
