atrium upper right or left chamber of the heart
endocardium membrane lining the cavities of the heart
epicardium membrane forming the outer layer of the heart
interatrial septum partition between the right and left atria
interventricular septum partition between the right and left ventricles
myocardium heart muscle
pericardium protective sac enclosing the heart composed of two layers with fluid between
visceral pericardium layer of the pericardium closest to the heart ( visceral = pertaining to organ )
parietal pericardium outer layer ( parietal = pertaining to wall)
pericardial cavity fluid-filled cavity between the pericardial layers
ventricle lower right or left chamber of the heart
heart valves structures within the heart that open and close with heartbeat to regulate the one way flow of blood
radiology x-ray imaging
angiography process of x-ray imaging a blood vessel after injection of contrast dye, most commonly after catheter placement
angiogram record obtained by angiography
coronary angiogram x-ray image of the blood vessels of the heart using a catheter to inject contrast
arteriogram x-ray image of a particular artery
aortogram x-ray image of the aorta
venogram x-ray image of a vein
multiple-gated acquisition (MUGA) scan nuclear image of the beating heart in motion made as radioactive isotopes are injected in the bloodstream and traced through the heart's chambers; useful in evaluating the pumping function of the ventricles
positron emission tomography (PET) scan of the heart use of specialized nuclear isotopes and computed tomographic techniques to produce perfusion (blood flow) images and to study the cellular metabolism of the heart; can be performed at rest or with stress
myocardial radionuclide perfusion stress scan nuclear perfusion scan of the heart that is made before and after the induction of controlled physical exercise (treadmill or bicycle) or a pharmaceutical agent that produces the effect of exercise stress in patients who are unable to ambulate
myocardial radionuclide scan of the heart made after an intravenous injection of an isotope (ex: thallium) that is absorbed by myocardial cells in proportion to blood flow throughout the heart; useful in evaluating coronary artery disease (CAD)
