Through implant patient registry and investigation, it was learned a 25mm 11500a aortic valve was explanted at implant due to disruption of the right coronary sinus (after decannulation).The explanted device was replaced with another 25mm 11500a aortic valve with pericardial patch repair of the aortic root.Per medical records, the patient presented with severe nonrheumatic native aortic valve stenosis and underwent a avr.Intraoperatively the heavily calcified native valve was removed, annulus decalcified and sized.A 25mm 11500a was inserted in the supra-annular position with 16 interrupted pledget mattress sutures and secured with cor-knots.The valve was seated well below the coronary ostia.Tee demonstrated normal functioning valve.After weaning from bypass and administration of protamine, bleeding started to emanate from the anterior surface of the aortic root.The patient was recannulated.A stellate disruption of the rc sinus just above the valve adjacent to the left right commissure was identified.The valve was removed, bovine pericardial patch was used to correct the defect.Another 25mm 11500a was implanted and was seated well below the coronary ostia.Post tee demonstrated normally functioning aortic valve and normal biventricular function.The patient was transferred to the icu in critical condition.On pod #4, the patient was discharged home with aspirin 81mg qd in stable condition.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.

The device was not returned to edwards for evaluation as it is not available.The investigation is still in progress; therefore, a conclusion has yet to be established.A supplemental report will be submitted accordingly upon investigation completion.Edwards will continue to review and monitor all events.Trends are monitored on a monthly basis and if action is required, appropriate investigation will be performed.
