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 0.05).

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. Renal failure was diagnosed in none of the patients. Thromboembolic complications were more frequently encountered in patients with hemolysis. In order to prevent anemia and sideropenia, it is recommended that control may be exercised over hemolysis and iron content in the blood of patients with prosthetic heart valves.
