Heart-lung transplantation in situs inversus

Reconstruction was accomplished in a 2 heart-lung recipients with situs inversus resulting in a left-sided systemic venous atrium. We created a large common atrium that was closed on the left side, leaving an atrial cuff on the inferior right quadrant. To this we anastomosed the donor right atrium, which had been opened laterally between the cavae. This resulted in some clockwise rotation of the ventricles and anterior positioning of the apex. The right pulmonary veins passed superior to the atrial anastomosis and posterior to the donor right atrium. Cardiopulmonary function was excellent in both cases.
