013-A
Aortic injection study in a dog with a large patent ductus arteriosus and pulmonic regurgitation. Note the funnel shaped patent ductus arteriosus (PDA) and the large diameters of the aortic arch (AA) and the pulmonary trunk (PT).
013-B
Continued aortic injection study in the dog with a large patent ductus arteriosus. Dilation of the pulmonary trunk (PT) separates the pulmonic valve leaflets and allows pulmonic valve regurgitation (arrow) into the right ventricle (RV).
