  9. OVERVIEW

  10. Dilation of the pulmonary vessels http://www.flickr.com/photos/pulmonary_pathology/4348915356/

  11. Umbilical vein turn into ligamentum teres and umbilical arteries turn into medial umbilical ligaments http://www.indiana.edu/~anat550/cvanim/fetcirc/fetcirc.html

  12. The interatrial septum forms http://www.flickr.com/photos/andygural/4098952495/sizes/m/in/photostream/

  13. Ductus venosus becomes the ligamentum venosum http://www.indiana.edu/~anat550/cvanim/fetcirc/fetcirc.html

  14. Defects • Patent Ductus Arteriosus • When the Ductus Arteriosus fails to close after birth • Abnormal blood flow between aorta and pulmonary artery • Twice as common in girls as in boys • Sometimes goes away by itself

  15. Patent Ductus Arteriosus http://www.nhlbi.nih.gov/health/health-topics/topics/pda/

  16. Defects • Patent Foramen Ovale • Most common Atrial Septal Defect (ASD) • Hole between the atria does not close • Affects 25% of the population • Can cause a stroke or heart attack

  17. Patent Foramen Ovale http://my.clevelandclinic.org/disorders/patent_foramen_ovale_pfo/hic_patent_foramen_ovale_pfo.aspx

  18. Other defects • Aortic Stenosis • Atrioventricular Canal Defect • Coarctation of the Aorta • Hypoplastic Left Heart Syndrome • Pulmonary Atresia • Pulmonary Stenosis

  19. More Defects • Total Anomalous Pulmonary Venous Connection • Transposition of the Great Arteries • Tricuspid Atresia • Truncus Arteriousus • Ventricular Septal Defect
