Edwards received notification of a pascal precision ace procedure in mitral position.During procedure, air embolism was suspected, but no air bubbles were seen in echo.Patient presented in overall good condition with no abnormalities before the procedure.As reported, patient became hemodynamically unstable after the implant system (is) left the guide sheath (gs) in the left atrium.The blood pressure briefly dropped below 40 mmhg systolic and medication was administered.The patient became stable again after a few minutes.A search was made for a possible cause, but nothing was found.The device was flushed properly and without any problems.No air was drawn during aspiration and no st elevation was noticed during the case.The procedure could then be continued normally without complications.As per one proctor present, a short-term irritation of the conduction system was also suspected.Starting mitral regurgitation (mr) grade was 4, and final mr grade was 1.

The following sections were updated/corrected/added: b4, d4, g3, g6, h2, h6 and h11 the complaint for inadequate aspiration, air remaining in device during insertion was confirmed with other empirical evidence.No manufacturing non-conformities were found in the investigation.Available information suggests the device may have led to an air embolism or a short-term change in the conduction system that may have contributed to the reported event.However, a definite root cause is unable to be determined.
