Detailed knowledge of the origins of the pulmonary and coronary arteries is vital for surgical management.

In 63 (90%) patients, there was aortic dominance, while 7 (10%) had dominance of the pulmonary component. In 27 (43%) patients with aortic dominance, part of the pulmonary segment arose from a truncal valvar sinus. A long confluent pulmonary channel was more common in patients with sinusal origin compared to those with non-sinusal origin of the pulmonary segment (19 vs. 0; P\u2009=\u20090.0005). Close proximity between the orifices of the coronary arteries and the pulmonary component was also more frequent with sinusal origin (21 vs. 6; P\u2009&amp;lt;\u20090.001) with 5 (19%) patients having pulmonary flow obstructed by a truncal valvar leaflet.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Sinusal origin of the pulmonary component is common with aortic dominance, frequently in association with a long confluent pulmonary segment, which may be in close proximity to the origin of a coronary artery. One-fifth of patients with sinusal origin of pulmonary component have a truncal valvar leaflet obstructing the pulmonary orifice. These morpho-anatomic findings have important implications for management.<\/jats:p>\n
