We thank the authors for their commentsReference Meyer-Szary and Kwiatkowska ¹ on our recent report of hearts exhibiting crossed pulmonary arteries. As we explained in our report,Reference Hernandez, Anderson, Hoggard, St. Louis and Shepard ² it was Jue, Lockman, and Edwards who originally described this fascinating arrangement of the pulmonary arteries, publishing their contribution in 1966.Reference Jue, Lockman and Edwards ³ It was the lack of previous reports on crossed pulmonary arteries in association with hypoplasia of the transverse aortic arch that motivated us to highlight our findings. We are in complete agreement with their suggestion that this entity is almost certainly commoner than appreciated at present, and we endorse their suggestion that seekers are likely to end up as finders. We presume that, in their patient with common arterial trunk, their reference to “double outflow” was meant to indicate the right ventricular origin of the common trunk. We would also suggest that cases such as they describe are better considered as showing pulmonary dominance, as the great advances in diagnosis that they report now indicate the need for similar advances in nomenclature. We hope that they will agree that alphanumeric schemes of classification are much inferior to the provision of specific descriptions.
