    PRODUCT EVENT SUMMARY: THE PUMP WAS NOT RETURNED FOR EVALUATION. THE REPORTED EVENT WAS CONFIRMED VIA REVIEW OF THE CONTROLLER LOG FILES WHICH REVEALED AN INCREASE IN POWER CONSUMPTION AND ESTIMATED FLOW STARTING ON 15 OCT 2018 AND A STEADY DECREASE IN POWER CONSUMPTION AND ESTIMATED FLOW STARTING ON 01 NOV 2018 . TEN HIGH WATT ALARMS WERE LOGGED SINCE 19 OCT 2019 AND FIFTY-ONE LOW FLOW ALARMS WERE LOGGED SINCE 02 NOV 2018. BASED ON HISTORICAL REVIEW OF SIMILAR HIGH POWER EVENTS, THE MOST LIKELY ROOT CAUSE OF THE HIGH POWER EVENT MAY BE ATTRIBUTED TO EXTERNAL FACTORS SUCH AS THROMBUS FORMATION OR INGESTION. BASED ON RISK DOCUMENTATION, MULTIPLE FACTORS MAY HAVE CONTRIBUTED TO THE LOW FLOW EVENT INCLUDING BUT NOT LIMITED TO THROMBUS AT THE INFLOW CANNULA OR OUTFLOW GRAFT, CONSTRICTION AT THE OUTFLOW GRAFT, AND OR POOR VAD FILLING. 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. MEDTRONIC, INC. (MEDTRONIC) IS SUBMITTING THIS REPORT TO COMPLY WITH 21 C.F.R.
