Abstract
The method of photochromic imaging was used to study the flow structure behind MEDINZh artificial cardiac valves. The flow structure behind three models of MEDINZh artificial cardiac valves (basic bicuspid model and two models under development) was studied experimentally under conditions of model physiological flow. Momentary flow rate profiles demonstrating the dynamics of the flow structure behind the valves were determined at various stages of the valve operation. The flow structure behind the artificial cardiac valves was studied in two perpendicular planes. The flow structure in front of the valves at the closing stage was also studied. The hemolysis level was experimentally determined under conditions of model physiological flow for the following six models of artificial cardiac valves: bicuspid valves CARBOMEDICS (USA), MEDINZh (Russia), MEDINZh N (Russia), and ROSCARDICS (Russia); disk valve MIKS (Russia); and a tricuspid valve (Germany).
