[Comparative study of hemolysis in patients after implantation of Soviet-made artificial heart valves and spherical and angle-opening disc closing devices].

Intravascular hemolytic parameters were studied in 40 patients after implantation of Soviet-made cardiac values with a ball versus angle-opening disc closing device. It was found that with the angle-opening disc closing cardiac valves "LIKS" and "EMIKS", hemolysis developed considerably more infrequently and was less marked than with ball valves. A significant difference was found between the activity of lactate dehydrogenase and the levels of haptoglobin in the compared groups of patients (p less than 0.

[The effect of intravascular hemolysis on the body of rheumatics with heart valve prostheses].

The rate of intravascular hemolysis and associated complications was studied in 100 patients with rheumatic heart disease within 2 to 20 years after replacement of the heart valves. Hemolysis of varying intensity was recorded in 72% of patients, anemia in 5%, hemosiderinuria in 27%, cholelithiasis in 4%, and sideropenia in 36.8% of the examined.
