During a cardiac catheterization procedure, a small balloon at the tip of the catheter is inflated in order to open up a coronary artery by flattening the blockage, leaving a stent in place to keep the artery open. This is called: a. coronary artery bypass graft b. implantable cardioverter defibrillator c. pacemaker d. percutaneous transluminal angioplasty e. valvuloplasty _____ 78. The surgical repair or replacement of a heart valve is called a. coronary artery bypass graft b. implantable cardioverter defibrillator c. pacemaker d. percutaneous transluminal angioplasty e. valvuloplasty

The  epicardium (also the visceral pericardium) is the outer layer of the heart wall. 2. The cardiac cycle consists of one round of  diastole  (relaxation and filling phase) and   systole  (contraction and pumping phase). 3. The conduction system consists of the sinoatrial node (initiates the stimulus), the internodal pathway, the   atrioventricular  node, the atrioventricular bundle, the left and right   bundle branches  , and finally the   Purkinje  fibers. 4. As the heart muscle is stimulated and contracts, the electrical activity can be detected and recorded by an  electrocardiograph . 5. The   inferior vena cava  carries deoxygenated blood from the lower regions of the body to the right atrium. 6. The   superior vena cava  carries deoxygenated blood from the upper regions of the body to the right atrium. 7. The  aorta  is the largest artery in the body, that carries oxygenated blood from the left ventricle to systemic arteries. MATCHING _____ 1. An AV valve located between the right atrium and ventricle _____ 2. An AV valve between the left atrium and ventricle _____ 3. A valve that prevents backflow into the left ventricle _____ 4.
