The hospital indicated that on (b)(6) 2015, an emergency patient (myocardial infarction) was brought to the (b)(6) hospital after a full day of uneventful device use.The patient was prepared for intervention and brought to the exam room.Meanwhile, the system shut down by itself and the staff did not attempt to restart the system.Instead the patient was immediately taken to another hospital, (b)(6) hospital, where an intervention was completed successfully despite the unanticipated extended delay in treatment.Some period after the completed intervention, the patient was being transferred back to (b)(6) hospital at which time they expired.The ge healthcare medical director confirmed that because the issue extended the delay possibly affecting the prognosis, the device failure may have been a contributing factor in the ultimate outcome.It has been determined during troubleshooting that this issue was due to an intermittent failure of the r5 relay within ce power distribution box (pdb) of the vascular system which caused the intermittent system shut down.This relay is used to control voltage and phase of the facility power supply.Autopsy did not reveal any specific malfunction of the r5 relay.No pattern has been identified with r5 relay.The site has been corrected on july 23, 2015 by replacing the r5 relay.After replacement of the component, the ce pdb and system were up and running.No further action is required.
