Differential pulmonary flow after heart transplantation in patients with malposition of the great arteries.
In transposition of the great arteries the right lung is preferentially perfused, and this may be due to the orientation of the right pulmonary artery when the main pulmonary artery comes off in a posterior position. In this study the mean perfusion of the right lung was 61% in six patients who had "correction" of the great artery malposition at the time of heart transplantation. This suggests that anatomic correction of pulmonary artery orientation does not correct the preferential perfusion to the right lung.
