H10: additional manufacturer narrative: 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.

Edwards received information that a patient with a19mm 3300tfx pericardial aortic valve was hospitalized for very severe aortic stenosis (as) and mild paravalvular leak secondary to structural valve deterioration after an implant of approximately two (2) years and nine (9) months.A symptom of dyspnea on exertion was seen.While hospitalized, the patient went into cardiopulmonary arrest (cpa) and balloon aortic valvuloplasty (bav) was performed while the patient was on extracorporeal membrane oxygenation (ecmo).Ecmo was weaned off, however, percutaneous cardiopulmonary support (pcps) was introduced for worsening of heart failure symptoms due to as.The patient underwent valve in valve procedure with a 20mm sapien 3 urtra while the patient was on pcps.The patient's status was reported as "under treatment in icu".A 72- year-old female with a medical history of chronic renal failure, chronic dialysis (since 17 years ago), s/p aortic valve replacement (avr) to correct as and coronary artery bypass graft (cabg).

Tissue degeneration-related structural deterioration, either calcific or non-calcific, are common chronic failure modes for this type of bioprosthetic heart valve.Operational mechanical stress and biological factors are generally believed to be the major contributors to the non-calcific bioprosthetic tissue degeneration.Structural valve deterioration (svd) can, and typically does, lead to chronic central leaks over a period of time.Svd is the most common reason for bioprosthesis explant and encompasses multiple failure modes, including calcification, noncalcific degeneration, dehiscence, cusp thickening or fibrosis, or a combination of these.Such failure modes may occur singularly or concomitantly.Degeneration-related structural deterioration is most commonly related to patient factors and is not usually an indication of a device malfunction.The most likely cause is patient factors, including chronic dialysis and history of coronary artery bypass graft (cabg).
