The first heart transplantation in the Nordic countries was performed at Rikshospitalet, Oslo in 1983. In this paper, we present our experience with this treatment up to 1999. 317 heart transplantations have been performed, an average of 23 transplantations per year. 82% of the recipients were males; 50% had heart failure due to coronary heart disease. Mean age of the recipients was 47 years (range 1-64). Our indications and contraindications are similar to most other transplantation centres. Triple immunosuppression with ciclosporin, prednisolone and azathioprine have been used as standard treatment. The survival rate after one and ten years are 85% and 53% respectively, with a significantly higher survival rate among recipients younger than 50 at transplantation, especially if the graft was from a donor younger than 35 years. The most common early postoperative complications were acute cellular rejections and infections. Transplant accelerated coronary heart disease and cancer were the main causes of late death. We believe that close co-operation between Riskshospitalet and local centres will provide the best treatment for patients needing a heart transplant.
