The reported issue involves the following syncardia temporary total artificial heart (tah-t) system components and is reported under two separate medical device reports: (1) 70 cc tah-t l/n 108279 (mfr report # 3003761017-2018-00107) and (2) companion 2 driver s/n (b)(4) (this mfr report).The customer, a syncardia certified hospital, reported that on (b)(6) 2018 the patient was taken to interventional radiology for a new iv placement via the right internal jugular vein.During the procedure, the guide wire was reported by the customer to have entered the right atrium and then became stuck in the valve of the tah-t right ventricle.The customer also reported that they have a picture of the wire stuck in the valve and that the radiologist confirmed that the guidewire was withdrawn with force to free it from the valve.It was also reported that the wire appeared to have been completely withdrawn and was not believed to be broken in any way upon removal.The customer also reported that for the undetermined amount of time that the valve was stuck, the companion 2 driver supporting the patient exhibited very low fill volumes and cardiac output alarms.The customer also reported that after approximately 50 minutes, the companion 2 driver was exchanged and the low fill volumes and associated hypotension resolved.The customer also reported that, prior to the capture of the guidewire in the right ventricle, the patient was stable but acidotic, receiving bicarbonate and vasopressors to maintain blood pressure and his end organs were not doing well.He was on continuous hemofiltration for renal dysfunction.The customer also reported that on (b)(6) 2018 the patient's neurologic status was assessed with eeg and it was determined that there was no neurologic function.Care was withdrawn from the patient on (b)(6) 2018.The customer also reported that they plotted graphs of the patient data file from the companion 2 driver as well as performed a system checkout on the companion 2 driver and indicated that the companion 2 driver appeared to function as intended.
