An event of a patient presenting with shortness of breath and leg swelling due to heart failure was reported.A more comprehensive assessment, including a histopathological examination of the valve tissue, could not be performed as the device remains implanted and was not returned for analysis.However, based on the information received, the reported event is consistent with structural valve deterioration (svd), which is a well-known complication of tissue heart valve replacement surgery.A variety of factors may contribute to svd, including patient, biological, and implant-related factors: no implant related factors could be confirmed from the information received from the field as information related to implant procedure only indicated that there was no allegation against the device.Biological factors which can result in tissue degeneration, such as calcification (from patient conditions predisposing to elevated calcium like renal disease etc.) or thinning of the prosthetic leaflet tissue (predisposing to leaflet tears) also could not be confirmed as the valve was not returned for histopathological examination.The device history record was also reviewed to ensure that each manufacturing and inspection operation was performed and that the product met all specifications.Based on the available information, the root cause of the reported event could not be conclusively determined.There is no indication of a product quality issue with regards to manufacture, design, or labeling.
