  1. aneurysm
    a weakness in the arterial wall resulting in ballooning of the artery and possible rupture
  2. apex
    the lower left tip of the left ventricle of the heart; also, the rounded upper potion of each lung.
  3. arrhythmia
    • an abnormal heartbeat
    • aka-dysrrhythmia
  4. arteriosclerosis
    a disease characterized by the buildup of cholesterol deposits in the arterial lining.
  5. bradycardia
    a slow heart rate (usually a heart rate under 60 beats per minute in a adult)
  6. cardiac cycle
    the pumping action of the heart from one beat to the next.
  7. cardioplegia
    intentional stopping of the heart during cardiac surgery
  8. coarctation
    a congenital narrowing or stricture in the descending thoracic aorta.
  9. congenital
    a condition present at birth
  10. cross-clamp
    to place a clamp across a structure to occlude it
  11. diastole
    that phase of the cardiac cycle when the ventricles contract
  12. endovascular repair
    endoscopic surgery of the vascular system
  13. fibrillation
    uncoordinated muscular activity in the heart muscle, which results in a "quivering" rather than pumping action
  14. fusiform aneurysm
    a type of aneurysm that involves the entire circumference of a blood vessel.
  15. heart-lung machine
    medical device used during cardiac bypass. Systemic blood is shunted out of the body via cannulas, which are implanted in the heart. The device collects the blood, removes excess carbon dioxide, oxygenates it, and returns it to the body through separate cannulas
  16. infarction
    necrosis and death of tissue related to obstruction of blood flow
  17. ischemia
    reduced blood supply to tissue; may be resulting from a obstruction within the blood vessels or external pressure, which acts as a tourniquet
  18. off-pump procedure
    a procedure performed without a cardiopulmonary bypass (i.e., "the pump")
  19. pacemaker
    a device that stimulates the heart muscle to contract.
  20. preclotting
    the process of soaking a graft or patch of synthetic graft material in the patient's blood or plasma before insertion. Most grafts no longer need preclotting.
  21. saccular aneurysm
    a type of aneurysm in which a saclike formation with a narrow neck projects from the side of the artery.
  22. shunt
    to bypass a structure or carry fluid from one anatomical location to another
  23. stenosis
    the narrowing of a hollow structure such as a blood vessel or duct
  24. sternotomy
    an incision made into the sternum
  25. systole
    a phase of the cardiac cycle in which the ventricles contract
  26. tachycardia
    a fast heart rate (usually over 120 beats per minute in the adult)
  27. thoracotomy
    an incision made into the thoracic cavity
