narrowing of a vessel, especially the aorta
deep vein thrombosis (DVT)
blood clot that forms deep in the veins of the body, especially hose in legs or thighs
In DVT, blood clots may break away from the vein wall and travel in the body. If they lodge in the lung the condition is called pulmonary embolism.
ejection fraction (EF)
calculation of how much blood a ventricle can eject with one contraction
The left ventricular EF averages 50% to 70% in healthy hearts but can be markedly reduced if part of the heart muscle dies, as evident after an MI or in cardiomyopathy or valvular disease

implantable cardioverter-defibrillator (ICD)
implantable battery-powered device that monitors and automatically corrects ventricular tachycardia or fibrillation by sending electrical impulses to the heart
In ventricular fibrillation, the heart quivers rather than beats,and blood is not pumped to the brain. Unless treatment is received within 5-10 minutes, ventricular fibrillation causes death
area of tissue that undergoes necrosis following cessation of blood supply
local and temporary deficiency of blood supply due to circulatory obstruction
mitral valve prolapse (MVP)
common and occasional serious condition in which the leaflets of the mitral valve prolapse into the left atrium during systole causing characteristic murmur heard on auscultation
Common signs of and symptoms of MVP include palpitations of the heart and occasionally, panic attacks, with pounding heartbeat. Because of the possibility of valve infection, prophylactic treatment with antibiotics is suggested before undergoing invasive procedures such as dental work
procedure to restore normal rhythm of the heart by applying a controlled electrical shock to the exterior of the chest
sensation that the heart is not beating normally, possibly including thumping, fluttering, skipped beats, or a pounding feeling in the chest

circulation of blood through tissues or the passage of fluids through vessels of an organ
tetralogy of fallot
congenital anomaly consisting of four elements: (1) pulmonary artery stenosis, (2) inter ventricular septal defect, (3) transposition of the aorta, so that both ventricles empty into the aorta, (4) right ventricular hypertrophy caused by increased workload of the right ventricle
slender threadlike device used to hold open vessels, tubes, or obstructed arteries
stents are used to support tubular structures that are being anastomosed or to induce maintain patency within the tubular structures
blood clot that obstructs a vessel
cardiac catheterization (CC)
passage of catheter into the heart through a vein or artery to provide a comprehensive evaluation of the heart
CC gathers information about the heart, such as blood supply through the coronary arteries and blood flow and pressure in the chambers of the heart as well as enabling blood sample collection and x-rays of the heart
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
ECGs help diagnose abnormal heart rhythms and myocardial damage
Holter monitor test
ECG taken with a small portable recording system capable of storing up to 24 hours of ECG tracings
Holter monitoring is particularly useful in obtaining cardiac arrhythmia record that would be missing during an ECG of only a few minutes
nuclear ECG
ECG that utilizes a radioisotope to evaluate coronary blood flow
In a nuclear stress test, the radioisotope is injected at the height of exercise. The area not receiving sufficient oxygen is visualized by decreased uptake of the isotope
stress test
ECG taken under controlled exercise stress conditions
cardiac enzyme studies
blood test that measures troponin T, troponin I, and creatinine kinase (CK-MB)
cardiac enzymes are released into the bloodstream from damaged heart muscle tissue. Their presence in a blood specimen is consistent with myocardial damage

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
The MUGA scan shows the motion of the heart wall muscle and the ventricles ability to eject blood
Imaging technique that provides graphic display of heart sounds and murmurs during the cardiac cycle
A transducer sends ultrasonic pulses through the chest wall and the echoes are converted into images on a monitor to assess overall cardiac performance
diagnostic test that uses radiation emitted by the body after injection of radioactive substances to create images of various organs or identify body functions and diseases
scintigraphy identifies infarcted or scarred areas of the heart that show up as "cold spots" (areas of reduced radioactivity), taken when patient is at rest

percutaneous transluminal coronary angioplasty (PTCA)
dilation of an occluded vessel using a balloon catheter under fluoroscopic guidance
In PTCA, the physician inserts a catheter transcutaneously, inflates the balloon thereby dilating the narrowed vessel, and commonly positions a stent to hold the vessel open
removal of material from an occluded vessel using a specially designed catheter fitted with a cutting or grinding device
catheter ablation
deconstruction of conduction tissue tissue of the heart to interrupt the abnormal conduction pathway causing arrhythmia, thus allowing normal heart rhythm to resume
