Catheterization Questions with Correct Answers
Cardiac Catheterization (cath) Correct Answer-a specialized study of the
heart in which a catheter (thin, hollow, flexible tube) is inserted into an
artery and/or vein in the patient's arm, neck, or groin
Protocol of inserting catheter: Correct Answer-The Cardiologist follows
a designated protocol and used special equipment such as a needle,
guide-wire, sheath, and stopcock. It's guided into the patient's left or
right heart.
Left Heart Cath- Percutaneous Correct Answer-most popular method:
percutaneous -through the skin, femoral artery approach; frequently
performed with a pigtail catheter which travels from the femoral artery
to the aorta, coronary arteries, AV, and LV
Right Heart Cath Correct Answer-most popular method: femoral vein
approach; frequently performed with a Swanz-Ganz catheter which
travels from the femoral vein to the IVC, RA, TV, RV, PV, and PA; it
can also travel from the RA through the IAS into the LA = transeptal
procedure.
Indication Correct Answer-identify & determine the extent of
CAD/IHD. -Evaluate LV function. -Assess VHD; -Assess myocarditis
disease, such as cardiomyopathy; - -Myocardial biopsy as required post
heart transplant or for the evaluation of myocarditis; -Verify and support
non-invasive data; -Determine the necessity for surgical correction of
any of the above.
, Fluoroscopy (fluoro) Correct Answer-an x-ray technique with a screen
that provides immediate visualization inside the body. It's essential for
proper placement of the catheter, it can be used whenever visualization
within the body is needed.
Cineangiography or Digital Correct Answer-cine stores movies on 35
mm x-ray film; most labs store DIGITAL computerized images known
as cine-less.
Coronary Angiogram Correct Answer-one of the most popular studies
performed in the cath lab; assess the coronary arteries for CAD
CAD Correct Answer-the result of plaque build up within the lumen of
the coronary arteries that creates blockages; these blockages cause
insufficient blood flow through the diseased coronary artery(s)
Angioplasty
"Percutaneous Transluminal Coronary Angioplasty"
"PTCA" Correct Answer-performed by means of a catheter with a small
balloon attached to it; the catheter is placed within the lumen of the
coronary artery (transluminal) and the balloon is inflated at the level of
the plaque; the pressure from the inflated balloon presses the plaque
against the wall of the artery
Stenting Correct Answer-usually performed in conjunction with
angioplasty; a small expandable wire tube; once the angioplasty is
