Heart transplant in a patient with complete absence of the pericardium.

We report the case of a heart transplant in which the recipient patient had a total congenital absence of the pericardium. Associated with this, we found a major disproportion between the size of the recipient's mediastinal cavity and the size of the donor's heart. To prevent twisting of the great arteries, we placed the graft on the left diaphragm muscle and beneath the left lung, which resulted in an uneventful early and late postoperative course.
