    A SUPPLEMENTAL REPORT IS BEING SUBMITTED FOR DEVICE ANALYSIS. PRODUCT EVENT SUMMARY: THE VENTRICULAR ASSIST DEVICE (VAD) WAS NOT RETURNED FOR EVALUATION. THE REPORTED HIGH POWER EVENT WAS CONFIRMED VIA REVIEW OF THE AVAILABLE AUTOLOGS REPORT REVEALED A SLIGHT INCREASE IN POWER CONSUMPTION STARTING (B)(6) 2020, FOLLOWED BY A SHARP INCREASE IN POWER CONSUMPTION ON (B)(6) 2020, LEADING TO PARAMETERS ABOVE THE NORMAL OPERATING RANGE. A SUBSEQUENT SUDDEN DECREASE IN POWER CONSUMPTION WAS THEN LOGGED ON (B)(6) 2020. 99 HIGH WATT ALARMS AND 17 LOW FLOW ALARMS WERE LOGGED SINCE (B)(6) 2020. OF NOTE, IT WAS REPORTED THAT THE PATIENT WAS TREATED WITH PLASMINOGEN ACTIVATOR (TPA) AFTER WHICH THE POWER AND FLOW DECREASED. BASED ON THE AVAILABLE INFORMATION, THERE IS NO EVIDENCE TO INDICATE THAT A DEVICE MALFUNCTION OR PERFORMANCE ISSUE CAUSED OR CONTRIBUTED TO THE REPORTED EVENT. BASED ON THE AVAILABLE INFORMATION, THE MOST LIKELY ROOT CAUSE OF THE HIGH POWER EVENT CAN BE ATTRIBUTED TO EXTERNAL FACTORS SUCH AS THROMBUS FORMATION/INGESTION. BASED ON THE RISK DOCUMENTATION, POSSIBLE CAUSES OF THE LOW FLOW EVENT MAY BE ATTRIBUTED TO MULTIPLE FACTORS INCLUDING BUT NOT LIMITED TO POOR VAD FILLING, THROMBUS AT THE INFLOW CANNULA/OUTFLOW GRAFT, CONSTRICTION AT THE OUTFLOW GRAFT, AND/OR INAPPROPRIATE VAD ROTATIONAL SPEED. PER THE VAD INSTRUCTIONS FOR USE, DEVICE THROMBUS IS A KNOWN POTENTIAL COMPLICATION ASSOCIATED WITH THE IMPLANTATION OF AN HVAD PUMP. THERE WAS 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.
