[Atypical heart transplantation. Technical considerations. Apropos of a case].

A heterotopic heart transplantation was performed on a patient placed on circulatory assistance with a Biomedicus pump for ten days using a heart taken from a donor with situs inversus. In relation to this case, the authors describe the technical procedures allowing transplantation of a heart obtained from a donor with situs inversus into a heterotopic position and an orthotopic position or a normal heart in a recipient with situs inversus. Lastly, in the case of complex cardiac malformations with preservation of the lungs, they present the procedures allowing heart transplantation in cases of situs incertus, anomalies of venous return and transposition of the great vessels.
