title: [Anatomical and hemodynamic evolution at midpoint follow-up with the assisted heart in heterotopic heart transplantation. Apropos of 21 cases].
abstract: Between November 1978 and March 1985, 27 cardiac transplant operations were performed at the Arnault Tzanck Institute; Barnard's heterotopic method was used in 21 cases. In 16 cases, follow-up was prolonged to assess the effects on the assisted receiving heart. In the first postoperative hours the receiving heart is often more effective than the graft. There were no pathological consequences due to the two different rhythms. The increased pressures in the right cavities of the receiving heart decreased but sometimes this look several weeks. The volume of the left atrium decreased. Left ventricular contraction was unchanged in some cases but in others it improved significantly. This was accompanied by an average decrease of 20 mm in echocardiographic left ventricular end diastolic internal dimension. This technique of heterotopic assistance seems particularly suitable for advanced stages of cardiomyopathy with stage IV pulmonary hypertension.
