Valve explant at implant is typically a result of inappropriate sizing, difficulty seating, distortion of the valve, valve displacement before or after frame expansion, and/or the patients 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.The device was not returned for evaluation, as it was discarded.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 learned that a 23m pericardial aortic valve was explanted at implant due to oversizing.During suturing, patient annulus got torn.The device was explanted, and the torn site was repaired with a patch.The surgeon commented that the patient's annulus tear was caused by the sizing mistake.The device was replaced with a 21mm valve while the patient was on bypass with no adverse patient events reported.The patient status was reported as recovering.The device was originally implanted for aortic valve replacement to correct aortic stenosis and regurgitation.

H10: additional narratives: updated d4, h4, and h6 per new information received.The most likely cause is procedural factors.The device history record (dhr) was reviewed and showed that this device met all manufacturing and sterilization specifications for product release prior to distribution.No issues were identified that would have impacted this event.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.
