The article, "redo mitral valve replacement using st.Jude medical mechanical prosthesis via transseptal approach in a patient with degenerated mitral epic bioprosthesis: a video presentation", was reviewed.The article presented a case study of a 58-year-old male patient.It was reported that on an unknown date, a 29mm epic valve was implanted in the patient's mitral valve.It was reported 12 years post-procedure on an unknown date, the patient presented with severe bioprosthetic degeneration.A decision was made to reoperate and replace the valve with a 29mm unknown abbott mechanical heart valve.The article concluded that elective institution of cardiopulmonary bypass through femorofemoral arteriovenous cannulation prior to sternotomy prevents accidental injury to the cardiac chambers and great vessels during sternal entry.Pulmonary artery venting and cannulation of the superior vena cava further facilitate dissection of the cardiac chambers without causing injury.Placement of two stay sutures on the prosthetic annulus and intracapsular dissection greatly facilitates explantation without causing rupture of the atrioventricular groove.[the primary and corresponding author was ujjwal kumar chowdhury, all india institute of medical sciences, new delhi, 110029, india, with corresponding e-mail: ujjwalchow@rediffmail.Com].
