Mod9 (cardiac catheterization) Flashcards
Cardiac Catheterization
the insertion and passage of a small catheter into femoral or radial artery via a sheath; the catheter is advanced into coronary arteries via the aorta
coronary angiography
x-ray to see within blood vessels; to see location and severity of atherosclerotic lesions; GOLD STANDARD for diagnosis of CAD and for making treatment decisions
left ventriculography
x-ray to assess varying degree of wall segment abnormality
hypokinesis
type of left ventriculography wall abnormality; decrease in endocardial thickening and wall motion
akinesis
type of Left ventriculography wall abnormality; no endocardial thickening or motion
dyskinesis
type of left ventriculography wall abnormality; paradoxical wall motion
aneruysmal
type of left ventriculography wall abnormality; weakened bulging distortion
Supravalvular aortography
x-ray to evaluate arterial blood flow; assess aortic regurgitation, narrowing, aortic aneurysm
Intravascular ultrasound (IVUS)
visualize lumen of coronary artery to determine severity of stenosis
Fractional Flow Reserve (FFR)
used to determine pressure gradient across blockage
Right heart catheterization (swan-ganz)
catheter is placed in right side of heart and arteries leading to lungs; helps to assess right heart functinon, HF, cardiac tamponade, RCM
Stenosis
narrowing of blood vessel resulting in reduced blood flow
Ischemia
restriction of blood flow to tissue
Coronary atherectomy
treatment to remove atherosclerotic plaque using catheterization
directional atherectomy
plaque removed with inflation of balloon that pushes blade toward plaque; plaque cut off and stored in special chamber
