[Should the presence of coiled blood flow in the left heart ventricle and aorta be taken into consideration when constructing artificial heart valves?]. / Sleduet li uchityvat' nalichie zakruchennogo potoka krovi v levom zheludochke serdtsa i aorte pri konstruirovanii iskusstvennykh klapanov?

The use of an original device developed by the authors which was introduced in the blood flow in experiments in dogs has confirmed the presence of coiled blood flow in different parts of the aorta. The rate, direction and angle of coiling were calculated. The results obtained suggest that the fact of coiling the blood flow should be taken into account when constructing new models of artificial valves of the heart in order to decrease the energy value of the cardiac output, to prevent injury of the formed elements of blood and thrombogenesis.
