Model Number	IMPELLA CP
Medical Device Problem Code	Adverse Event Without Identified Device or Use Problem (2993)
Health Effect - Clinical Code	Hemolysis (1886)
Date of Event	01/04/2020
Type of Reportable Event	Death
Event or Problem Description
The complainant reported that a patient endured hemolysis during impella cp support.Following implant, the patient began to develop hematuria.The support level was reduced to p-2 and the device was repositioned to address the condition.The following day, the decision was made to explant the pump as the hemolysis had not yet resolved.The patient passed away the next day.There is not enough evidence to exclude the impella as an associated factor in the patient's outcome.
Additional Manufacturer Narrative
The impella device was not received from the customer, therefore, investigation of the device was not possible.Should the device or any new information be received, a supplemental mdr will be filed.As noted in the impella instructions for use: impella cp with smartassist system, section: potential adverse events (united states): ¿acute renal dysfunction, aortic valve injury, bleeding, cardiogenic shock, cerebral vascular accident/stroke, death, hemolysis, limb ischemia, myocardial infarction, renal failure, thrombocytopenia and cardiac or vascular injury (including ventricular perforation).¿ section: use of echocardiography for positioning of the impella catheter: ¿evaluate the position of the impella catheter if the automated impella controller displays position alarms or if you observe lower than expected flows or signs of hemolysis.If the catheter does not appear to be correctly positioned, initiate steps to reposition it.¿ impella catheter too far into the left ventricle: ¿obstruction of the impella catheter inlet area can lead to increased mechanical forces on blood cell walls and subsequent hemolysis, which often presents as dark or blood colored urine.¿ section: hemolysis: ¿hemolysis should be monitored during support.Patients who develop high levels of hemolysis may show signs of decreased hemoglobin levels, dark or blood-colored urine, and in some cases, acute renal failure.Plasma-free hemoglobin (pfhgb) is the best indicator to confirm whether a patient is exposed to an unacceptable level of hemolysis.¿ ¿patient conditions¿ including catheter position, pre-existing medical conditions, and small left ventricular volumes¿ may also play a role in patient susceptibility to hemolysis.¿ section: suction: ¿suction may occur if the blood volume available for the impella catheter is inadequate or restricted.Suction limits the amount of support that the impella catheter can provide to the patient and results in a decrease in arterial pressure and cardiac output.It can damage blood cells, leading to hemolysis.It may also be an indicator of right heart failure.¿.
