Cardiac transplantation is the ultimate therapeutic option in end-stage CHF. Orthotopic cardiac transplantation is the surgical technique of choice, whereas heterotopic cardiac transplantation is performed primarily when there is high resistance in the pulmonary circulation of the recipient (and a heart-lung transplantation is impossible), the donor heart is too small, or in selected cases with acute but potentially reversible heart failure. In orthotopic transplantation the donor heart is joined to the recipients atria, aorta, and pulmonary artery. In heterotopic transplantation, the donor heart is implanted into the right thoracic cavity and anastomosed with the recipient s heart in a complex maimer in such a way that the donor heart takes over most of left ventricular output, while the recipient s heart continues to ensure right ventricular output. 

Several systems are now available for circulation support. Ventricular assist devices (VAD) are mechanical pumps that can take over the circulatory function of the left ventricle (LVAD), the right ventricle (RVAD) or both ventricles (biventricular assist device - BVAD). The patient s native heart remains in place, and the VADs are implanted in a heterotopic position. Connection between the heart chambers and the great vessds is usually achieved... 

Heterotopic heart transplantation (h-HTX) was clinically established by Barnard and Losman (1977), who first implanted an auxiliary heart. The...
