On (b)(6) 2013, a mitral valve replacement (mvr) was performed and this 27 mm epic valve was implanted.At the end of 2017, the patient developed dyspnea and severe mitral regurgitation (mr) was diagnosed.When an echocardiography and a computed tomography (ct) were performed, one of the leaflets of this valve was suspected to be torn.On (b)(6) 2018, a re-do mvr was performed and this valve was explanted and replaced with a 25 mm carpentier-edwards perimount magna ease mitral heart valve.

The reported event of a torn leaflet was confirmed.Dyspnea and mitral regurgitation was also reported.Gross morphological and histopathological examination found cusps 1 and 3 were torn and cusp 2 had been previously excised.Fibrous pannus ingrowth was present on the outflow surface of cusp 1, which led to retractions in the cusp.No acute inflammation or significant calcifications were found.The device history record was reviewed to ensure that each manufacturing and inspection operation was performed.The cause of the reported event remains unknown; however, dyspnea and regurgitation are consistent with torn and retracted leaflets.
