Additional manufacturer narrative: 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 product malfunction.However, partial, or total occlusion of the ostia, if unrecognized, can result in angina, myocardial infarction, acute ventricular dysfunction and/or death.The root cause of this event cannot be determined with the available information.It is unknown if the patient and/or procedure-related factors may have caused or contributed to this event.There has been no allegation of a product malfunction.The subject device is not available for evaluation as it was never received.The device history record (dhr) review was completed and this device passed all manufacturing and sterilization inspections prior to release for distribution.Edwards will continue to review and monitor all reported events.Trends are monitored on a monthly basis and if action is required, an appropriate investigation will be performed.If any new information is received, a supplemental report will be submitted accordingly.

Through implant patient registry, it was learned that a patient with a 23mm 11500a aortic valve was explanted at implant due to obstruction of the coronary ostium.The explanted valve was replaced with a non-edwards valve.Per the medical records, the patient previously placed homograft was densely calcified with perforation of both the left and right leaflets.The ostia were low-lying, and a full root repair was not unexpected.The patient underwent an aortic root enlargement with a bovine pericardial patch and a 23mm 11500a was implanted.The aorta was closed but there was new lv hypokinesis and multiple arrhythmias.There was ostial obstruction, so the valve and patch were explanted.The subsequent root replacement was successful, using a 25 mm non edwards valve within a pig root, and a 26mm dacron graft.The patient tolerated the procedure well and was transferred to the icu in stable condition.On pod #4, the patient was discharged home in stable condition, on new oxygen, cardiac, antiplatelet, and diuretic therapy.Edwards lifesciences maintains an implant patient registry.This registry is a patient tracking mechanism for serialized edwards implantable devices (bioprosthetic heart valves and annuloplasty rings), rather than a true post-market surveillance registry.Through the registry, edwards is notified when these devices are implanted.In addition, patient and/or device status may be reported to the registry via the implantation data cards.The information is received from various sources (e.G.Surgeon, hospital, and patient family members) and is not received in the form of a conventional "customer complaint".The information reported may or may not be related to the edwards device.
