    INVESTIGATION OF THIS EVENT IS PENDING AND A SUPPLEMENTAL REPORT WILL BE SENT UPON ITS COMPLETION. PRODUCT EVENT SUMMARY: THE VENTRICULAR ASSIST DEVICE (VAD) WAS NOT RETURNED FOR EVALUATION. THE REPORTED LOW FLOW/POWER EVENT WAS CONFIRMED THROUGH REVIEW OF THE CONTROLLER LOG FILES WHICH REVEALED A SHARP DECREASE IN POWER CONSUMPTION AND ESTIMATED FLOWS TO PARAMETERS BELOW THE NORMAL OPERATING RANGE ON (B)(6) 2021, WITH A SUBSEQUENT RETURN TO BASELINE PARAMETERS ON (B)(6) 2021. A SECOND SHARP DECREASE IN POWER CONSUMPTION AND ESTIMATED FLOWS WAS LOGGED ON (B)(6) 2021. 102 LOW FLOW ALARMS WERE RECORDED SINCE (B)(6) 2021. THERE WAS NO EVIDENCE OF A SUCTION EVENT WITHIN THE ANALYZED PERIOD. INFORMATION PROVIDED BY THE SITE INDICATED THAT THE PATIENT WAS ADMITTED INTO THE INTENSIVE CARE UNIT (ICU) DUE TO POTENTIAL PUMP THROMBUS. THE PATIENT IMPROVED AFTER VOLUME WAS GIVEN FOR A LOW HEMOGLOBIN AND HEMATOCRIT AND AN ECHOCARDIOGRAM SHOWED NO ABNORMALITIES. BASED ON THE AVAILABLE INFORMATION, THERE IS NO EVIDENCE TO SUGGEST THAT A DEVICE MALFUNCTION CAUSED OR CONTRIBUTED TO THE REPORTED EVENT. BASED ON RISK DOCUMENTATION, POSSIBLE CAUSES OF THE REPORTED LOW FLOW/POWER EVENT MAY BE ATTRIBUTED TO MULTIPLE FACTORS INCLUDING BUT NOT LIMITED TO THROMBUS AT THE INFLOW CANNULA/OUTFLOW GRAFT, CONSTRICTION AT THE OUTFLOW GRAFT, AND/OR POOR VAD FILLING. PER THE INSTRUCTIONS FOR USE, DEVICE THROMBUS IS A KNOWN POTENTIAL COMPLICATION ASSOCIATED WITH THE IMPLANTATION OF A VAD. THERE IS NO EVIDENCE THAT THE PATIENT HAD A HISTORY OF THROMBUS 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. INVESTIGATION OF THIS EVENT IS COMPLETED AND THE FILE WILL BE CLOSED. IF NEW INFORMATION IS RECEIVED, THE FILE WILL BE RE-OPENED AND A SUPPLEMENTAL WILL BE SUBMITTED.
