It was learned through implant patient registry that a patient with a 21mm 2700tfx aortic valve underwent a valve-in-valve procedure after an implant duration of 6 years, nine months due to unknown reasons.The tavr was performed with a 23mm 9750tfx transcatheter valve.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.

H11: additional manufacturer narrative: the subject device is not available for evaluation, as it remains implanted in the patient.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 reported events.Trends are monitored on a monthly basis and if action is required appropriate investigation will be performed.

H11: additional manufacturer narrative: updated sections: h6 (type of investigation, investigation findings, and investigation conclusions).The subject device is not available for evaluation, as it remains implanted in the patient.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 reported events.Trends are monitored on a monthly basis and if action is required, appropriate investigation will be performed.A device history record (dhr) review was not performed, as no information regarding a device failure mode was provided.Furthermore, there is no allegation of a malfunction which could be related to a manufacturing non-conformance and/or one was not suspected or confirmed through investigation; no labeling non-conformance/deficiency; no device-related infection; and no evidence of a product failure with regard to design, reliability, or use error.Engineering evaluation summary: attempts have been made to obtain missing information; however, to date, no response has been received.Since there is no information regarding an allegation of a device malfunction, an engineering evaluation is not required.Based on the information available, a definitive root cause cannot be conclusively determined.Despite repeated attempts to obtain further information regarding this event, no additional information has been received from the customer at this time.All pertinent information available to edwards lifesciences has been submitted.
