Event Description
|
Edwards received information that a patient with a 19mm 11500 aortic valve implanted approximately fifty-four (54) days was explanted due to aortic stenosis and moderate to severe regurgitation.The jet was from the commissure between the right and the non-coronary cusps detected by the echo image.There were no patient symptoms.The device was replaced with a 19mm non-edwards mechanical valve without any adverse event reported.There was no visual abnormality observed on the explanted valve.Per the report from the physician, one leaflet was in open position and the other two leaflets were in closed position.He suspected that the distortion of the cobalt-chromium alloy band which was either from the beginning or caused by knotting the suture ring contributed to develop asr.The patient status was reported as recovered.

Product evaluation: customer reports of stenosis and regurgitation were unable to be confirmed.The x-ray demonstrated commissures 1 and 3 were bent inward and leaflet 3 was wavy.X-ray also demonstrated the cocr band remained intact and the vfit cocr alloy band was not expanded.Suture holes were visible around the sewing ring.No other visible inconsistencies were observed from the valve.Based on the information available, a definitive root cause is unable to be determined, however, patient and/or procedural factors likely caused or contributed.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.
