1

passage of a catheter into the heart through a vein or artery to provide a comprehensive evaluation of the heart

cardiac catheterization

2

graphic line recording that shows the spread of electrical excitation to different parts of the heart using small metal electrodes applied to the chest, arms, and legs

electrocardiogram (ECG)

3

ECG taken with a small portable recording system capable of storing up to 24 hours of ECG tracings

Holter monitor test

4

ECG that utilizes a radioisotope to evaluate coronary blood flow. In a nuclear stress test, the radioisotope is injected at the height of exercise. Areas not receiving sufficient oxygen are visualized by decreased uptake of the isotope

nuclear test

5

ECG taken under controlled exercise stress conditions

stress test

6

blood test that measures troponin T, troponin I, and creatinine kinase (CK-MB). They are released into the bloodstream from damaged heart muscle tissue

cardiac enzyme studies

7

series of tests (total cholesterol, HDL, LDL, and triglycerides) used to assess risk factors of ischemic heart disease

lipid panel

8

radiographic imaging of the heart and blood vessels after injection of a contrast dye

angiography

9

angiography to determine the degree of obstruction of the arteries that supply blood to the heart

coronary angiography

10

angiography in which two radiographic images are obtained, the first one without contrast material and the second one with , and then compared by a computer that digitally subtracts the images of soft tissues, bones, and muscles, leaving only the image of vessels with contrast

digital subtraction angiography (DSA)

11

radiological examination of the aorta and its branches following injection of a contrast medium via a catheter

aortography

12

noninvasive diagnostic method that uses ultrasound to visualize internal cardiac structures and produce images of the heart

echocardiography (ECHO)

13

noninvasive adaptation of ultrasound technology in which blood flow velocity is assessed in different areas of the heart

doppler ultrasound

14

noninvasive technique that uses radiowaves and a strong magnetic field to produce multiplanar cross-sectional images of blood vessels

magnetic resonance imaging (MRI)

15

nuclear procedure that uses radioactive tracers to produce movie-like images of the structures of the heart, including the myocardium and the mitral and tricuspid valves

multiple-gated acquisition (MUGA)

16

imaging technique that provides a graphic display of heart sounds and murmurs during the cardiac cycle

phonocardiography

17

diagnostic test that uses radiation emitted by the body after an injection of radioactive substances to create images of various organs or identify body functions and disease

scintigraphy

18

scintigraphy procedure that uses injected radioactive thallium and records the uptake of the isotope with a gamma camera to produce an image

thallium study (resting)

19

radiography of a vein after injection of a contrast medium to detect incomplete filling of a vein, which indicates obstruction

venography

20

procedure to restore normal rhythm of the heart by applying a controlled electrical shock to the exterior of the chest

cardioversion

21

technique used to block blood flow to a site by passing a catheter to the area and injecting a synthetic material or medication specially designed to occlude a blood vessel

embolization

22

injection of a chemical irritant (sclerosing agent) into a vein to produce inflammation and fibrosis that destroys the lumen of a vein

sclerotherapy

23

procedure that alters a vessel through surgery or dilation of the vessel using a balloon catheter

angioplasty

24

surgical procedure that uses a vessel graft from another part of the body to bypass the blocked part of a coronary artery and restore blood supply to the heart muscle

coronary artery bypass graft (CABG)

25

dilation of an occluded vessel using a balloon catheter under fluoroscopic guidance

percutaneous transluminal coronary angioplasty (PTCA)

26

removal of material from an occluded vessel using a specially designed catheter fitted with a cutting or grinding device

atherectomy

27

removal and examination of a small piece of tissue for diagnostic purposes

biopsy

28

removal and examination of a segment of an arterial vessel wall to confirm inflammation of the wall or arteritis (a type of vasculitis)

arterial biopsy

29

destruction of conduction tissue of the heart to interrupt the abnormal conduction pathway causing the arrhythmia, thus allowing normal heart rhythm to resume

catheter ablation

30

surgical separation of the leaflets of the mitral valve, which have been fused together at their "commisures" (points of touching)

commissurotomy
