Summary
A 3-month-old boy, mildly cyanosed and tachypneic, was found by cineangiography to have a nonbranching main pulmonary artery arising from the right ventricle and connecting to the descending aorta via a large persistent ductus arteriosus. The left and right pulmonary arteries arose as a common “trunk,” before branching, from the ascending aorta. Complete surgical correction was performed at 7-months of age. Subsequent cardiac catheterization has demonstrated normal pressures and blood oxygen saturation in all right-heart chambers and the great arteries.
