Event Description
|
It was reported that an unknown sized epic stented tissue valve was implanted in a mitral position on unknown date.On an unknown date, regurgitation was confirmed by an echocardiography.Redo mvr was conducted on (b)(6) 2022.The epic valve was explanted and unknown valve was implanted instead.Perforation was confirmed on the epic leaflets corresponding leaflet location for p2 to p3 and p3, and the posterior leaflet remained open position which caused regurgitation.Patient stable, no additional information was provided.

Additional information sections: d9, h2, h3, h6, h10.Explant due to regurgitation reported.The investigation found that all three cusps were torn.All three cusps had marked thinning and loss of collagen fibers at the cusp base.No acute inflammation or significant calcifications were present.In the absence of any calcification or evidence for infection, the reported event is consistent with a non-calcific leaflet tear.A non-calcific leaflet tear is a form of structural valve deterioration (svd), which is a well-known complication from valve replacement surgery.A non-calcific leaflet tear is commonly attributed to increased operational leaflet stress but may also be related to biological factors which result in tissue degeneration characterized by loss of collagen.In this case, histological evaluation did demonstrate loss of collagen at the tear sites, which could have contributed to the formation of the tear.
