    CLINICAL ASSESSMENT: 63 YEAR OLD MALE PATIENT TREATED WITH IMPELLA 5.5 DUE TO ACUTE MYOCARDIAL INFARCTION COMPLICATED BY CARDIOGENIC SHOCK. PATIENT WAS ADMITTED TO HOSPITAL FOR HEART FAILURE. PATIENT ACUTELY IN CARDIOGENIC SHOCK AND HAD CARDIAC ARREST IN CATHETER LABORATORY. PLACED ON EXTRACORPOREAL LIFE SUPPORT AND WHEN PATIENT LOST CONTRACTILITY AND EJECTION FRACTION WAS DEEMED 5 % EMERGENT IMPELLA 5.5 INSERTION DECISION WAS TAKEN. DURING INSERTION SHEATH PLACED AND HCP WAS UNABLE TO GET HEMOSTASIS. SHEATH APPEARS TO BE LEAKING AND DECISION WAS TAKEN TO REPLACE SHEATH WITH A NEW ONE. FIRST DAY OF SUPPORT PUMP EXPERIENCED DROP IN PURGE FLOWS WITHOUT SPIKES IN MOTOR CURRENT. NO FURTHER CHANGES IN OTHER PUMP METRICS AND NO PURGE PRESSURE ALARMS AS WELL AS NO LEAKS IN THE SYSTEM. DECISION WAS TAKEN FOLLOWING MD CONSULTATION TO EXCHANGE PURGE FOR TISSUE PLASMINOGEN ACTIVATOR. DAY SIX OF SUPPORT PATIENT DECANNULATED FROM EXTRACORPOREAL LIFE SUPPORT AND EXPERIENCED NEUROLOGICAL DELAYS AND POSSIBLE STROKE SYMPTOMS - THIS IS CONSERVATIVELY CODED FOR STROKE IN THIS CASE TO THE IMPELLA 5.5, BUT DUE TO MULTIPLE MECHANICAL CIRTULATORY SUPPORT SYSTEMS CANNOT SOLELY BE ATTIBUTED TO THE IMPELLA SYSTEM. DAY SEVEN OF SUPPORT PATIENT HAD TO BE REINTUBATED DUE TO INCREASED SECRATION. DAY 14 OF SUPPORT THE PLACEMENT SIGNAL AND THE MEASURED BLOOD PRESSURE WERE NOT CORRSPONDING. FOLLOWING ONE MONTH OF SUPPORT PLATELET DECREASE WAS NOTED AND CODED HERE FOR THROMOCYTOPENIA. RESULT WAS ECHO MESUREMENT AND POSSIBLE REPOSITIONING - AS NO FURTHER INFORMATION AVAILABLE CONSERVATIVELY CODED TO DEVICE REPOSITIONING HERE. PATIENT EXPERIENCED FREQUENT PURGE ALARMS WITH FLOW RANGING FROM 8 TO 11.5 ML/HR AND NO CHANGES IN PURGE PRESSURE. TUBING AND CASSETTE WERE CHECKED. NEXT DAY AFTER MORE ALARMS DECISION MADE TO CHANGE PURGE CASSETTE. AFTER ONE MONTHS AND TWO DAYS OF SUPPORT NOTED PLACEMENT SIGNAL FLICKERING IN AND OUT - NO FURTHER INFORMATION AND CI WAS MENTIONED TO BE PLACED, BUT NOT IN SYSTEM. PATIENT SUCCESSFULLY BRIDGED TO TRANSPLANT AFTER ALMOST TWO MONTHS OF IMPELLA 5.5 SUPPORT, WHICH IS BEYOND THE RECOMMENDATIONS IN THE INSTRUCTIONS FOR USE. THE USE OF MULTIPLE MECHANICAL CIRCULATORY SUPPORT SYSTEMS, SUCH AS COMBINED IMPELLA AND EXTRACORPOREAL CIRCULATORY LIFE SUPPORT (ECLS) THERAPY, IS ASSOCIATED WITH AN INCREASED RISK OF ADVERSE EVENTS DUE TO THE CUMULATIVE COMPLEXITY OF THE SUPPORT STRATEGY AND THE ADDITIVE DEVICE-RELATED RISKS. IMPELLA SUPPORT WAS CONTINUED BEYOND THE RECOMMENDED 14 DAY DURATION; PROLONGED USE CAN INCREASE THE RISK OF COMPLICATIONS AND THEREFORE MAY HAVE PLAYED A CONTRIBUTORY ROLE IN THIS ADVERSE EVENT. ENGINEERING ASSESSMENT: DURING IMPELLA 5.5 SUPPORT, THE PATIENT EXPERIENCED ISSUES WITH PURGE PRESSURE. AT THE END OF THE IMPELLA 5.5 IMPLANT PROCEDURE, PURGE FLOW DROPPED FROM 8 TO 3 ML/HR. THERE WERE NO MOTOR CURRENT SPIKES AND FLOW WAS IN RANGE. THE PHYSICIAN CHOSE TO USE TPA PURGE WHICH RESOLVED THE PURGE FLOW ISSUE, INDICATING THAT MEDICATION WAS REQUIRED SO THEREFORE THE IMPACTED PRODUCT WAS THE IMPELLA 5.5 AND NOT THE PURGE SYSTEM ITSELF AT THAT POINT. APPROXIMATELY ONE MONTH INTO IMPELLA 5.5 SUPPORT, THE PATIENT EXPERIENCED NEW PURGE PRESSURE ISSUES. APPROXIMATELY ONE MONTH INTO SUPPORT, PURGE FLOW BEGAN RANGING FROM 8 TO 11.5 ML/HR WHICH APPROPRIATELY TRIGGERED WHITE PURGE FLOW ALARMS. THERE WERE NO CHANGES IN PURGE PRESSURE AND THE RN CHECKED THE PURGE LINE/TUBING, WITH NO NOTE OF ANY FINDINGS. THE NEXT DAY, PURGE FLOW INCREASE AND DECREASE ALARMS WERE FREQUENTLY WHICH INDICATES THE SYSTEM WAS OSCILLATING BETWEEN LOW AND HIGH PURGE PRESSURE. THE CARE TEAM DECIDED TO EXCHANGE THE PURGE CASSETTE WITH ABIOMED PHONE SUPPORT. THERE WERE NO FURTHER MENTIONS OF PURGE ISSUES WITH THE NEW PURGE CASSETTE IN PLACE, INDICATING THE PURGE PRESSURE ISSUES ONE MONTH INTO SUPPORT WERE LINKED TO A PURGE CASSETTE ISSUE. ON DAY 20 OF IMPELLA 5.5 SUPPORT, A PLACEMENT SIGNAL ISSUE AROSE. THE AORTIC PRESSURE MEASURED ON THE AUTOMATED IMPELLA CONTROLLER (AIC) WAS HIGHER THAN THE PATIENT'S BLOOD PRESSURE. THERE IS NO FURTHER MENTION OF THIS ISSUE. GIVEN THAT THERE WAS OTHER EQUIPMENT ACCESSIBLE TO TAKE THE PATIENT'S BLOOD PRESSURE MEASUREMENT, THIS ISSUE HAD NO PATIENT CONSEQUENCE.
