| Abstract: | Since 1984 27 heart transplantations (HTX) were carried out in 25 patients at the 2nd Department of Surgery, University of Vienna. The classic orthotopic technique of Lower and Shumway was used in all cases. Routine immunosuppression consisted of azathioprine and cyclosporin-A. In order to treat the main complications successfully, i.e. rejection and infections, we were compelled to establish an extensive follow up regimen. The early recognition of acute rejection was based on the findings obtained by cutaneous as well as epicardial ECG leads, in conjunction with cytoimmunological monitoring on the basis of RIA measurements of the serum levels of Neopterin and gamma-Interferon. Furthermore, we recorded some parameters of ventricular performance, such as the isovolumetric relaxation time and the radiologically measured heart volume. An endomyocardial biopsy was carried out to secure the diagnosis. Pulsed doses of methylprednisolone were used for the treatment of rejection, facultatively combined with ATG in the absence of improvements. Infections were pinpointed by comprehensive serum tests and various blood, sputum and urine cultures. The management consisted of treatment with the requisite antibiotics. Of 25 primarily transplanted patients 15 patients are still alive. 5 persons, amongst them 2 children, have survived already for more than 1 year. 6 patients died at an early stage. In 3 cases the cause of death was intractable infection. In 1 case multi-organ failure occurred and 1 patient died due to acute organ failure. 4 patients died at a late stage and acute severe rejection was responsible in all these cases.(ABSTRACT TRUNCATED AT 250 WORDS) |
