Clinical and Hemodynamic Performance of the Sorin Mitroflow Pericardial Bioprosthesis

The fate of small-size pericardial heart valve prostheses in an older patient population

“…3 The Mitroflow aortic valve prosthesis (LivaNova, London, United Kingdom) was specifically designed to reduce flow obstruction by minimizing the size and thickness of the sewing ring and by placing the pericardial leaflet on the outside of the stent post to maximize the valve opening area. 4 Because of its intrinsic manufacturing characteristics, a Mitroflow valve prosthesis can be easily implanted where other pericardial valves of corresponding size might not fit or would require an annulus enlargement. 5 The implant technique does not differ from that used for any kind of standard stented prosthesis.…”

Early Structural Valve Deterioration of the Mitroflow Aortic Bioprosthesis

“…The Mitroflow LX is a variation of the A12 and had minor revisions such as the use of an automatic sewing machine, reduction of sewing ring seams to 1 seam, and prefixation by glutaraldehyde rather than postfixation. 18 Both Mitroflow A11/12 and Mitroflow LX do not undergo antimineralization treatment. The most recent modification, Mitroflow with phospholipid reduction therapy, added this step.…”

Early Structural Valve Deterioration of Mitroflow Aortic Bioprosthesis

“…1 affect the design or performance of the prosthesis. 7 Therefore, both models can be considered the same bioprosthesis. 8 The major flaw of biological prostheses is the occurrence of structural valve deterioration (SVD) at mid or long term, which is variable depending on the type of prosthesis.…”
