  1. Patent Foramen Ovale
    Congenital anomaly.

    Opening between the two atria does not close after birth.
  2. Interventricular Septal Defect
    Congenital anomaly.

    • Abnormal opening in interventricular septum.
    • Allows oxygenated and deoxygenated blood to mix.
  3. Patent Ductus Arteriosus
    Congenital Anomaly.

    • Vessel between pulmonary trunk and aorta of fetus does not close.
    • Blood bypasses the lungs.
  4. Atrial Septal Defect
    Congenital Anomaly.

    Abnormal opening in interatrial septum between the two atria.
  5. Stenosis of Pulmonary Orifice
    Congenital Anomaly

    Narrowing of the opening between R ventricle and pulmonary trunk.
  6. Coarctation of Aorta
    Congenital Anomaly

    Narrowing of lumen of aorta, usually upper descending part.
  7. Tetralogy of Fallot
    Congenital anomaly characterized by:

    • Narrowing of pulmonary artery / valve
    • Ventricular Septal Defect
    • Overriding Aorta
    • Hypertrophied L Ventricle
  8. R Aortic Arch
    Congenital Anomaly

    Aortic arch is on R instead of L.
  9. Transposition / Dextracardia
    Congenital Anomaly

    Apex of heart points to the R, and base directed to the L.
  10. Thrombus
    Pahology

    Clot formed within a vessel or inside the heart.
  11. Phlebitis
    Pathology

    • Inflammation of lining of a vein.
    • Results in roughening of lining of the membrane.
  12. Thrombophlebitis
    Pathology

    Predisposition of patient to have thrombus form in vein due to roughening of lining membrane of vein caused by phlebitis.
  13. Embolus
    A foreign body obstructing a blood vessel.
  14. Infarct
    Condition produced in an organ due to the blocking blood flow to organ being blocked.
  15. Occlusion
    Closure of a vessel due to spasm, embolus, degeneration of vessel wall, etc.
  16. Coronary Occlusion
    Blocking of one of the coronary arteries to the heart, or a branch of it.
  17. Aneurysm
    • Bulging of the wall of a vessel due to weakness from disease of the vessel.
    • Common sites are: abdominal aorta and anterior and middle cerebral arteries.
  18. Arteriosclerosis
    Thickening of a vessel wall with replacement of normal tissue with fibrous tissue, fat, and calcium.
  19. Varicose Veins
    • Dilated veins due to weakening of vessel walls.
    • Valves cannot close properly and blood may flow in opposite direction than normal.
  20. Hemorrhoids
    • Dilated veins in the anal canal.
    • These frequently bleed.
  21. Esophageal varicosities
    Dilated veins in the lower part of esophagus which may bleed.
  22. Cardiac Hypertrophy
    • Enlarged heart.
    • Caused by enlargement of heart muscle tissue due to heart having to work harder to pump blood.
  23. Cardiac dilation
    • Cardiac enlargement due to stretching of heart muscle fibers
    • This causes heart muscle fibers to tire out and chambers to enlarge.
  24. Congestive Heart Failure / CHF
    • Heart cannot pump blood through is circuits
    • Causes abnormal accumuilation of blood in heart or tissues.
  25. Endocarditis
    Inflammation of internal lining membrane of the heart
  26. Myocarditis
    Inflammation of cardiac muscle
  27. Pericarditis
    • Inflammation of pericardium
    • Often with accumulation of fluid in pericardial sac
  28. Cardiac Infarction
    • Infarcted area of dead cardiac muscle resulting from cutting off of its blood supply.
    • It is replaced by fibrous tissue in survivors.
  29. Valvular Disease
    • Thickening, deformation, shrinking and fusion of the cusps of cardiac valves due to infection or degeneration.
    • Results in their inability to open and close completely.
  30. Stenosis
    A narrowing of an opening or canal
  31. Incompetence
    Failure of valve to close completely ( due to disease ) resulting in regurgitation of blood back into the chamber that it came from.
  32. Cardiography
    Radiography of the chambers of the heart using a contrast medium to fill them
  33. Arteriography
    Radiography of an artery and its branches by injection of contrast medium
  34. Aortography
    Radiography of the aorta by injection of contrast medium.
  35. Venography
    Radiography of a vein and it tributaries by injection of contrast medium.
  36. Lymphangiography
    Radiography of lymphatic vessels, nodes, and ducts by injection of contrast medium.
  37. Angiocardiography
    Combined radiographic examination of heart trunk veins and / or arteries by injection of contrast medium.
