Studies from Johns Hopkins University Have Provided New Data on Biomedicine and Biomedical Engineering (Computational Study of the Dynamics of a Bileaflet Mechanical Heart Valve in the Mitral Position)

By a News Reporter-Staff News Editor at Biotech Week -- Current study results on Biotechnology have been published. According to news reporting originating in Baltimore, Maryland, by NewsRx journalists, research stated, "A computational study of the flow-structure interaction of a bileaflet mechanical heart valve in the mitral position is presented. Flow in a simple model of the left ventricle is simulated using an immersed boundary method, and the dynamics of the valve leaflets are solved in a fully-coupled manner with the flow."

The news reporters obtained a quote from the research from Johns Hopkins University, "Simulations are conducted for two distinct valve orientations and multiple valve hinge locations, and the performance of the valve is compared in terms of metrics associated with leaflet motion, mitral regurgitation, and mechanical energy losses through the valve. Results indicate that a bileaflet mechanical heart valve with a more centrally located hinge, and implanted in the anatomical orientation provides the best overall performance."

According to the news reporters, the research concluded: "The fluid and leaflet dynamics, as well as the clinical implications underlying these findings are discussed."
