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.

It was reported and learned from medical records that, that a patient with a 23mm 3000tfx aortic valve underwent a valve-in-valve procedure after an implant duration of seven (7) years due to severe degeneration with stenosis and severe insufficiency.The patient presented with symptoms of heart failure nyha class 3.The procedure was performed with a 23mm 9755rsl transcatheter valve successfully.Per medical records, the patient presented with symptoms of heart failure, examination and imaging revealed sever bioprosthetic aortic valve degeneration with both insufficiency and stenosis.The patient underwent tavr using 23mm 9755rsl sapian 3 reselia transcatheter valve inside the failing 23mm 3300tfx magna ease aortic valve.Post-procedural tee demonstrated well seated prosthesis with no stenosis nor insufficiency, mean gradient of 2 mmhg.The patient tolerated the procedure well and transferred to the pacu in stable condition.The patient was discharged on pod #2.

H11: additional manufacturer narrative: svd is a logical and expected consequence of the chemical, mechanical, and immunological processes associated with bhv implantation.The common endpoint of all these factors is calcification and degradation.Svd is an acquired condition, intrinsic to bioprosthetic valves, characterized by deterioration of the leaflets or supporting structures, leading to thickening, calcification, tearing, or disruption of the prosthetic valve materials.These changes result in valvular dysfunction manifesting as stenosis and/or regurgitation with a consequent drop in hemodynamic efficacy of the valve.Despite the advancements in the heart valve industry, svd commonly begins 7-8 years after implantation, with a considerably increased rate in patients with pertinent comorbidities and/or an implant duration of greater than 10 years.Prior investigations and extensive literature review have shown that svd is predominantly related to patient factors and implant duration rather than to manufacturing issues.Events related to device design, manufacturing, or use error tend to manifest at an earlier implant duration.There is no evidence to suggest a manufacturing defect caused or contributed to the reported event.Based on the information available, the most likely root cause is patient factors, including an implant duration of 7 or more years and hyperlipidemia (hld), coronary artery disease (cad).Per the instructions for use (ifu), structural valve deterioration (svd) is a known potential risk associated with bioprosthetic heart valves.The device history record (dhr) was not reviewed as the reported event does not allege a malfunction that could be related to an edwards manufacturing deficiency and/or one was not suspected or confirmed through investigation, no labeling non-conformance/deficiency; no use-related issue with a hazardous situation; no device-related infection; and no evidence of a product failure with regard to design, reliability, or use error.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.
