Diagnostic and Therapeutic Procedures

cardiac catheterization (CC) 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 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 ECG that utilizes a radioisotope to evaluate coronary blood flow
cardiac enzyme studies Blood test that measures troponin T, troponin I, and creatinine kinase (CK-MB)
lipid panel Series of tests (total cholesterol, high density lipoprotein, low density lipoprotein, and triglycerides) used to assess risk factors of ischemic heart disease
angiography Radiographic imaging of the heart and blood vessels after injection of a contrast dye
coronary Angiography to determine the degree of obstruction of the arteries that supply blood to the heart
digital subtraction Angiography in which 2 radiographic images are obtained, the 1st 1 w/out contrast material and the 2nd one after a contrast material has been injected, and then compared by a computer that digitally - the images of soft tissues, bones, and muscles
aortography Radiological examination of the aorta and its branches following injection of a contrast medium via a catheter
echocardiography (ECHO) Noninvasive diagnostic method that uses ultrasound to visualize internal cardiac structures and produce images of the heart
Doppler ultrasound Noninvasive adaptation of ultrasound technology in which blood flow velocity is assessed in different areas of the heart
magnetic resonance imaging (MRI) Noninvasive technique that uses radiowaves and a strong magnetic field, rather than an x-ray beam, to produce multiplanar cross-sectional images of blood vessels
multiple-gated acquisition(MUGA) 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
phonocardiography phon/o: Imaging technique that provides a graphic display of heart sounds and murmurs during the cardiac cycle
scintigraphy 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 diseases
thallium study (resting) Scintigraphy procedure that uses injected radioactive thallium and records the uptake of the isotope with a gamma camera to produce an image
sclerotherapy Injection of a chemical irritant (sclerosing agent) into a vein to produce inflammation and fibrosis that destroys the lumen of the vein
venography Radiography of a vein after injection of a contrast medium to detect incomplete filling of a vein, which indicates obstruction
cardioversion Procedure to restore normal rhythm of the heart by applying a controlled electrical shock to the exterior of the chest
embolization embol: plug -izaton: process (of ) 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 tom 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 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
percutaneous transluminal coronary angioplasty (PTCA) per-: through Dilation of an occluded vessel using a balloon catheter under fluoroscopic guidance
biopsy Removal of material from an occluded vessel using a specially designed catheter fitted with a cutting or grinding device
arterial Removal and examination of a segment of an arterial vessel wall to confirm inflammation of the wall or arteritis, a type of vasculitis
catheter ablation Destruction of conduction tissue of the heart to interrupt the abnormal conduction pathway causing the arrhythmia, thus allowing normal heart rhythm to resume
commissurotomy Surgical separation of the leaflets of the mitral valve, which have fused together at their “commissures” (points of touching)
atherectomy ather: fatty plaque Removal of material from an occluded vessel using a specially designed catheter fitted with a cutting or grinding device
laser ablation Procedure used to remove or 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 Puncturing of the pericardium to remove excess fluid from the pericardial sac or to test for protein, sugar, and enzymes or determine the causative organism of pericarditis
thrombolysis thromb/o: blood clot Destruction of a blood clot using anticlotting agents called clot-busters, such as tissue plasminogen activator
intravascular 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; also called phlebotomy
