Event Description

It was reported that a 23mm 11060a valve, implanted in aortic position, was explanted after an implant duration of 1 day due to valve dehiscence and bleeding secondary to disruption of part of the bovine pericardial patch in the lvot.The explanted valve was replaced with a 23mm 11060a valve.Per medical records, 7 months earlier, the patient underwent cabg x1, avr, and aortic root replacement with a 23mm 11060 valved conduit for streptococcus mitis endocarditis [2022-13346-02].Recently, the patient presented for back pain and found to have type a aortic dissection and underwent emergent redo avr and conduit replacement.On pod#1, the patient was brought back to the or for mediastinal washout.A mediastinal clot was removed and drains were replaced.Upon closing the chest, a fresh blood was noted coming from the aortic root.It was found that the is a partial disruption of the bovine pericardial patch at the lvot causing dehiscence of the valved conduit.The implanted valve and conduit were explanted, pericardial patch was repaired, and a new 23mm 11060 valved conduit was implanted in replacement.The patient was coagulopathic and was transferred to the icu with an open packed chest.The patient was discharged on pod# 10 in hemodynamically stable condition.

Manufacturer Narrative

Valve dehiscence may occur early or late.When it occurs in the early post-operative period, it is typically a result of an inadequate prosthetic valve implantation in combination with friable myocardial tissue.Late dehiscence can occur as a result of successive dilatation of cardiac structures that result from progression of disease.Valve dehiscence is not a malfunction of the device.Reports of device issues (e.G., damage) related to patient and/or procedural factors without evidence or allegation of malfunction do not require engineering evaluation.The most likely cause is procedural factors, including a disruption of part of the bovine pericardial patch in the lvot (per the medical records, there was necrotic tissue subjacent to the patch and the most distal portion of the patch had separated at the level of aortic annulus where the adjacent annulus was disrupted.).The root cause of this event was determined to be due to procedure related factors.The subject device is not available for evaluation, as it was discarded.The device history record (dhr) review was completed and this device passed all manufacturing and sterilization inspection prior to release for distribution.There were no issues 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.H10: additional manufacturer narrative: updated sections: d4 (expiration date), h4, and h6 (component code, impact code, clinical code, device code, type of investigation, investigation finding, and investigation conclusion).
