The St. JudeStandard, St. Jude Haemodynamic Plus, CarboMedics, Sorin Biomedica,Duromedics and ATS valves were studied. The mean pressure drop andeffective orifice area during forward flow, regurgitant volumes and totalenergy loss were analysed. The St Jude Haemodynamic Plus and SorinBiomedica valves had significantly lower forward flow pressure drops andtotal energy losses than the other four valves. Assuming that all sixvalves can be implanted in the equivalent size of aortic root, this shouldlead to improved in vivo performance. © Springer-Verlag European Journal of Cardio-Thoracic Surgery Elsevier Science B.V. 9/12(1995-12), 692-695 1010-7940 9:12<692 1995 9 ejcts https://doi.org/10.1016/S1010-7940(05)80127-7 text/html Onlinezugriff via DOI 1 abstract jats NATIONALLICENCE 856 40 https://doi.org/10.1016/S1010-7940(05)80127-7 text/html Onlinezugriff via DOI NATIONALLICENCE 773 0- European Journal of Cardio-Thoracic Surgery Elsevier Science B.V 9/12(1995-12), 692-695 1010-7940 9:12<692 1995 9 ejcts Metadata rights reserved CC BY-NC-4.0 http://creativecommons.org/licenses/by-nc/4.0 nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-oxford
