The device was not returned to edwards for evaluation.Attempts to retrieve the device and additional information are in process.The device history record (dhr) was reviewed and shows that this device met all manufacturing specifications for product release prior to distribution.No issues were identified that would have impacted this event.The event is reported as a valve explant at implant.This is typically a result of inappropriate sizing, distortion of the valve during implantation and/or the patient¿s anatomy, and not a malfunction of the device.There may be cases in which regurgitation is detected by tee prior to the completion of the surgical case and exchange of the valve is required.Explant of one valve and implant of another valve may result in complications.In this case, the patient underwent a concomitant cabg, switched to a smaller size valve, and expired during the procedure.Based on the information received the cause of the event cannot be determined.If additional information is received a supplemental mdr will be submitted.No further corrective or preventative actions are required at this time.Edwards lifesciences will continue to monitor all reported events.
