Additional information was reported from the sales rep.It was unable to confirm which pressure value was inaccurate.The indicated pressure value was from 20 to 30 mmhg on a monitor.The expected value was around 0 mmhg since it was after zeroing.The issue was resolved by replacing the catheter, therefore the malfunction of pressure transducer was not suspected.The patient was not treated based on the incorrect value.Certain amount of pressure was observed continuously on the pressure waveform.The pressure value and the waveform did not match.The sample of tracing was unavailable.No error message was observed.The value was not affected by the patient condition.The patient was male, and other information was unavailable.Although resistance was felt when inserting the guidewire, it was able to pass through the catheter.The customer suspected that inaccurate value was observed due to an occlusion inside one of the lumens.Further information could not be obtained.The reported event of pressure measurement issue and guidewire insertion issue were unable to be confirmed during product evaluation.Edwards pressure monitoring ifu rev.A state, poor dynamic response can be caused by air bubbles, clotting, excessive lengths of tubing, excessively compliant pressure tubing, small bore tubing, loose connections, or leaks.As received, liquid was observed inside of the balloon.An interlumen leak was observed between balloon inflation lumen and pa distal lumen at the backform.Balloon did not maintain its inflation due to leakage from pa distal hub.Other through lumens were patent without any leakage or occlusion.Recommended guidewire size for this model is 0.021 inches per japan ifu.Lab sample 0.021 inch guidewires passed through pa distal lumen from tip to hub and from hub to tip without any restrictions.No visible damage was observed from catheter body, balloon, and returned syringe.Further evaluation regarding related quality issues is under investigation.Complaint histories for all reported events are reviewed against trending control limits on a monthly basis and any excursions above the control limits are assessed and documented as a part of the monthly review.
