Hydrodynamic Performance of a Novel Sutureless Prosthetic Aortic Valve

The aim of the study was an in vitro hydrodynamic study of the developed prosthetic heart valve of the second generation, designed to carry out an implantation using “valve-in-valve” method. ...Prototypes of the developed prosthesis were studied under simulated physiological conditions of the heart using a Vivitro Labs pulse duplicator (Canada) in a comparative aspect with “UniLine” clinical commercial aortic valve bioprosthesis (Russia)... ...The design of the prosthesis under development has shown its consistency in terms of functional characteristics, both in comparison with the original UniLine prosthesis and with literature data....
