Midterm Outcome of Bioprosthetic Valve Replacement in North West of Iran

Abstract

Although valve repair is applied usually nowadays, particularly for mitral regurgitation (MR) or tricuspid regurgitation (TR), valve replacement using prosthetic valves is common especially in adults. Unfortunately the valve with ideal hemodynamic performance and long-term durability without increasing the risk of bleeding due to long-term anticoagulant therapy does not exist. Therefore patients and physicians must choose between bioprosthetic and mechanical valve. Currently clinical trends towards the increasing use of bioprosthetic valves instead of mechanical valves even in young patients apparently because of its advantages
