IU MED TERM Chap 8 Procedures & meanings

Chap 8 ProceduresChap 8 Procedures & Meanings
cardiac catheterization passage of a catheter into the heart through a vein or artery to provide a comprehensive evaluation of the heart
electrocardiogram (ECG, EKG) 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
Holter monitor test electrocardiogram (ECG) taken with a small portable recording system capable of storing up to 24 hours of ECG tracings
stress test ECG taken under controlled exercise stress conditions
nuclear stress test utilizes a radioscope to evaluate coronary blood flow
cardiac enzyme studies blood test that measures troponin T, troponin I, and creatine kinase (CK-MB)
lipid panel series of test (total cholesterol high density lipoprotein, low density lipoprotein, and triglycerides) used to assess risk factors of ischemic heart disease
aortography radiological examination of the aorta and its branches following the injection of a contrast medium via a catheter
coronary angiography radiological examination of the blood vessels of and around the heart
echocardiography noninvasive diagnostic method that uses ultrasound to visualize internal cardiac structures and produce images of the heart
Doppler ultrasound cardiography noninvasive adaptation of ultrasound technology in which blood flow velocity is assessed in different areas of the heart
magnetic resonance imaging (MRI) noninvasive imaging technique that uses radiowaves and a strong magnetic field rather than an x-ray beam to produce multiplanar cross-sectional images
magnetic resonance angiography magnetic resonance imaging technique used to visualize vascular structures
phonocardiography imaging technique that provides a graphic display of heart sounds and murmurs during the cardiac cycle
subtraction angiography imaging technique used to display soft tissue structures such as blood vessels without the confusing overlay of bone images
scintigraphy injection and subsequent detection of radioactive isotopes to create images of body parts and identify body functions and diseases
scintigraphy thallium study (resting) scintigraphy procedure that identifies infarcted or scarred areas of the heart that show up as "cold spots" (areas of reduced radioactivity), taken when the patient is at rest
venography radiography of a vein after injection of a contrast medium; incomplete filling of a vein indicates obstruction
cardioversion process of restoring the normal rhythmof the heart by applying a controlled electrical shock to the exterior of the chest
embolization 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 the blood vessel
angioplasty procedure that alters a vessel through surgery or dilation of the vessel using a balloon catheter
coronary artery bypass graft (CABG) surgical procedure that uses a vesel graft from another part of the body to bypass the blocked part of a coronary artery and restore blood supply to the heart muscle
percutaneous transluminal coronary angioplasty (PTCA) dilation of an occluded vessel using catheter under fluoroscopic guidance
atherectomy removal of material from an occluded vessel using a specially designed catheter fitted with a cutting or grinding device
biopsy removal and examination of a small piece of tissue for diagnostic purposes
arterial biopsy removal and examination of a segment of an arterial vessel wall to confirm inflammation of the wall or arteritis, a type of vaculitis
catheter ablation destruction of conductive tissue of the heart to interrupt abnormal contractions, thus allowing normal heart rhythm to resume
commissurotomy surgical seperation of the leaflets of the mitral valve, which have fused together at their "commissures" (points of touching)
laser ablation procedure used to remove and treat varicose veins
ligation and stripping tying a varicose vein (ligation) followed by removal (stripping) of the affected segment
open heart surgery surgical procedure performed on or within the exposed heart, usually with the assistance of a heart-lung machine
pericardiocentesis punturing of the pericardium to remove fluid to test for protein, sugar, and enzymes or determine the causative organism of pericarditis
phlebotomy incision or puncture of a vein to remove blood or introduce fluids or medications
thrombolysis destruction of a blood clot using anticlotting agents called "clotbusters" such as tissue plasminogen activator
intravascular thrombolysis infusion of a thrombolytic agent into a vessel to dissolve a blood clot
valvotomy incision of a valve to increase the size of the opening; used in treating mitral stenosis
venipuncture puncture of a vein by a needle attached to a syringe or catheter to withdraw a specimen of blood, perform a phlebotomy, instill a medication, start an intravenous infusion, or inject a radiopaque substance for radiological examination
