 | | Beginning at the ductus arteriosus, the course of blood flow in a typical PDA with pulmonary overcirculation is as follows: PDA, pulmonary artery, pulmonary capillaries, pulmonary veins, left atrium, left ventricle, aorta, PDA. |

 | | Procedural risks of PDA occlusion by catheter are few and largely influenced by the experience of the physician performing the procedure. |
