[Experimental study of the relationship of the level of blood hemolysis and the design of artificial heart valves]
Autor: Vn, Iurechko, Si, Korchagin, Am, Omel Ianchuk, George Itkin
Publikováno v: Europe PubMed Central
The paper deals with experimental studies into the level of hemolysis that accompanies the performance of artificial cardiac valves (ACV). The studies were conducted by two ways. The first study determined the level of hemolysis when artificial cardi
