The information provided to sjm indicated the patient underwent a double valve replacement procedure on (b)(6) 2012.A 21 mm sjm trifecta¿ valve was implanted in the aortic position and this 29 mm sjm epic¿ stented tissue valve was implanted in the mitral position.Postoperative course was characterized by implant of an sjm accent pacemaker.On (b)(6) 2014, the patient presented to the hospital with dyspnea, was treated with diuretic therapy, and was discharged.The patient presented to the hospital again on (b)(6) 2014 with severe pulmonary edema and was hospitalized.Transesophageal echocardiography revealed aortic insufficiency due to improper coaptation of the left coronary cusp.This mitral valve also showed transvalvular mitral insufficiency.The patient underwent a re-do double valve replacement procedure on (b)(6) 2014.During the explant procedure, the cusp corresponding to the left coronary sinus of the aortic trifecta¿ valve (medwatch report# 3008452825-2014-00034) was found to be detached near the annulus.One cusp of this mitral epic¿ stented tissue valve was found to be prolapsed.A 27 mm bioprosthetic valve from another manufacturer was implanted in the mitral position and a 21 mm bioprosthetic valve from another manufacturer was implanted in the aortic position.The patient was reported to be stable postoperatively.

(b)(4).The results of this investigation concluded a focal outflow thrombus on the base of cusp 3, fibrous pannus ingrowth on the inflow surface of cusp 1, a thin layer of fibrin on the inflow and outflow surfaces of all cusps, fibrin deposition within the bases of all cusps, and a tear on cusp 2.Special stains were negative for organisms, and no acute inflammation or significant calcifications were present.There was no evidence found to suggest the cause of fibrin, thrombus, pannus, and tear were due to an intrinsic defect in the valve, as supported by review of the valve's device history record and the analysis performed.The cause of the fibrin, thrombus, pannus, and tear remains unknown.
