Event Description
|
Edwards received notification that a right coronary artery (rca) obstruction occurred during implant procedure with a 11500a27 valve leading to a bypass graft.As reported, during procedure, a 27mm inspiris valve was implanted and all sutures were secured with a core-knot.During cardiopulmonary bypass weaning, a rise in st segments was noticed on the electrocardiograph (ecg).The surgeon suspected there was a dynamic obstruction from the strut of the valve to the right coronary ostia.For safety reasons, the surgeon elected to harvest a small amount of distal vein from the left leg and perform an off-pump anastomosis between the aortic graft and the proximal right coronary artery.The saphenous vein graft to rca was successful and the ecg normalized.The patient weaned easily from cardiopulmonary bypass and heparin was reversed with protamine before decannulation uneventfully.The patient was transferred to the intensive care unit in a satisfactory hemodynamic state and was eventually discharged home.

Manufacturer Narrative

Added information to section h6 (device code(s)), h6 (investigation findings) and h6 (investigations conclusions) corrected data h6 (device code(s)): "4001 - patient device interaction problem" code removed.The serial number was not provided.Therefore, the device history record (dhr) could not be reviewed.The device was not returned for evaluation.Partial or total occlusion or obstruction of the coronary ostia is a recognized complication of an aortic valve replacement.It is typically the result of a technical error during valve implant and not related to a device malfunction.The most likely cause is procedural factors.
