title: Plasmapheresis in the treatment of posttransplant cardiomyopathy.
abstract: After heart transplantation a number of factors such as pre- and postoperative hypoxia of the myocardium, myocardial failure of the early postoperative period, acute rejection episodes, cytomegalovirus infection, and finally the progressive atherosclerosis of the coronary arteries lead to the development of transplanted heart failure. Severe alterations of the myocardial function at this end stage of the process correspond to incurable cardiomyopathy. The target of plasmapheresis in this case is to decrease the extent of the disturbances in the lipoprotein contents and blood rheology for the improvement of the coronary perfusion of the transplanted heart. Nine patients with 3-7 year survival periods after heart transplantations underwent plasmapheresis twice a year using the Haemonetics PCS-plus machine. 2,100-2,700 ml of plasma was removed. Biochemical data, rheology and coagulation, and the concentration of Sandimmune (Sandoz Pharma Ltd., Basel, Switzerland) were controlled, and radionuclide scintigraphy of the myocardium, coronarographia, and transesophageal ultrasound investigations were completed for these patients. The result was the significant improvement of the coronary perfusion of the myocardium. The level of immunosuppression after the plasmapheresis procedures did not change and therefore did not demand any correction. Thus, we think that plasmapheresis can be an effective method of treatment of posttransplantation cardiomyopathy; the improvement of coronary perfusion decreases the extent of chronic ischemia. Further studies are necessary to answer the question as to whether it is possible to prolong the time before retransplantation with the help of plasmapheresis.
