Event Type  Death  

Event Description

It was reported a patient with a 33mm 11400m mitral valve implanted one (1) day underwent valve-in-valve procedure due to moderate to severe central regurgitation.The 33mm 11400m mitral valve was implanted and subsequently had significant regurgitation.The mvr was performed on an emergency basis.The patient had a bad anterior wall mi and was treated in the cath lab, but the patient needed an mvr due to a ruptured papillary muscle as a result of the mitral insufficiency.The surgeon described the regurgitation as moderate to severe central regurgitation but decided not to go back on pump given the condition of the patient.Patient was very sick from the mitral insufficiency and not in very good condition.The patient was put on balloon pump.Surgeon stated she removed the mitris holder system, both the handle and the holder, before securing the valve down with cor knots.Surgeon and ew rep discussed the possibility and likelihood that a suture may have entrapped one of the stent posts.The surgeon did not think that the patient would tolerate another pump run, so the decision was made with cardiology to a tmvr.The tmvr was performed with a 29mm 9600tfx.The patient post operative status noted as in recovery.

Manufacturer Narrative

The device was not returned to edwards for evaluation as it remains implanted.Attempts to retrieve additional information is in process.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 events.Trends are monitored on a monthly basis and if action is required, appropriate investigation will be performed.

Manufacturer Narrative

Added information to b2, b5, d4, h1, h2, h4, h6.The device history record 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 complaint is confirmed through receipt of medical records.Acute central leaks observed in the peri-operative period usually occur from technique related issues such as suture looping or chordae entrapment at the mitral position.Suture looping occurs when the surgeon inadvertently loops a suture over one of the commissural posts.The suture restricts the leaflet motion prohibiting coaptation resulting in central leak.These techniques are not typically the result of product malfunction; however, they may contribute to mild to severe regurgitation and if undetected may require reoperation.The most likely root cause is use error.

Event Description

Patient expired on pod# 4.

Event Description

It was reported and learned through follow-up that a patient with a 33mm 11400m mitral valve underwent valve-in-valve procedure on pod# 0 possibly due to stent posts entrapment by the suture causing leaflets not coapting and subsequent severe central regurgitation seen on post bypass echo.Per medical records, the patient was admitted s/p stemi, emergent pci x 4 stents; subsequently developed hypoxic respiratory failure, cardiogenic shock.The patient presented with anterior wall mi and a subsequent papillary muscle ruptured and native mitral valve regurgitation.The patient underwent emergency mvr with a 33mm 11400m mitral valve.It was notes that the surgeon removed both the handle and the holder before securing the valve down with cor knots.Post bypass echo showed moderate to severe mr, possibly due to stent posts entrapment by the suture.Given the preexisting mi, it was determined that the patient would not tolerate going back on pump to do explant at implant, so the decision was made to place a balloon pump and close the chest, planning do a transcatheter viv later.The patient was transported directly to the cath lab for emergent tmvr.He underwent successful tmvr with a 29mm 9600tfx transcatheter valve.The patient was transferred to icu after the procedure and was transported to tertiary hospital for further care same day after device implantation.
