RESUMO
PURPOSE: To report our initial clinical experience with heterotopic heart transplantation, stressing its indications and a new modification in surgical technique. METHODS: We studied three patients underwent heterotopic heart transplantation, using an original technique in one of them. This new technique allows to connect both pulmonary arteries without any prosthetic tube. RESULTS: One early death and two late survivors, with 17 and 20 months of follow-up. One of them is clinically well and practices sports, regularly. CONCLUSION: Heterotopic heart transplantation could be considered as a good therapeutic option for end-stage patients with cardiomyopathy and right pulmonary vascular resistance, specially those with right ventricle. It can improve general results of heart transplantation because it reduces the early risks related to hemodynamic problems in a selected group of patients.

PURPOSE: To assess this initial clinical experience with heart-lung transplantation in Brazil. METHODS: Four patients underwent heart-lung transplantation from December 1988 to March 1990, one patient with cardiomyopathy and high pulmonary resistance, two patients with primary pulmonary hypertension and another with pulmonary silicosis. The heart lung blocks were harvested from the donor using cardiopulmonary bypass and deep hypothermia. They were transplanted to the recipient by anastomosing the trachea, right atrium or venae cavae, and the ascending aorta. RESULTS: The second patient died on the 5th postoperative day due to respiratory insufficiency with consequent brain lesions. The first and third patients had survived nine months and 42 days respectively. The 4th patients is asymptomatic eight months after the operation. The main complications were bleeding in two patients, acute pulmonary rejection in three of them and obliterans bronchiolitis in one patients. CONCLUSION: The heart lung transplantation is a challenging procedure which results are progressively improving with the development of better surgical technique and clinical concepts.
