title: Ductal origin of the pulmonary artery in isolation: a case series.
abstract: We present three cases of ductal origin of a pulmonary artery in the absence of associated structural heart disease. No geographic or genetic explanation for the temporal occurrence of these cases could be identified. This series illustrates the importance of angiography in achieving an accurate diagnosis as well as appropriate surgical planning. An understanding of the embryologic origin of this lesion supports the strategic approach at catheterization as well as the surgical choice of interposition graft versus direct anastomosis. We report our experience and highlight diagnostic and surgical approaches to such patients based on the underlying embryology of this congenital cardiac anomaly.
