PURPOSE OF REVIEW Four different bileaflet mechanical prostheses are currently utilized for valve replacement in the United States. We reviewed the different designs, hemodynamic features, and long-term outcomes of each of these prostheses. RECENT FINDINGS Bileaflet mechanical valves provide excellent long-term durability and overall superb hemodynamic performance. Subtle design modifications have maximized the effective orifice area per given valve size, which minimizes outflow gradients in… CONTINUE READING
