smallest branches of arteries and veins
Cardioversion
Use of defibrillator paddles to restore normal rhythm of the heart by electrical shock
Chordae Tendineae
String like tendons linking papillary muscles to the tricuspid valve in the right ventricle and the mitral valve in the left ventricle
Conductive System
Generates and distributes electrical impulses over the heart and along the septum to stimulate contraction, allowing blood to move throughout the body
Contralateral
Situated on, pertaining to, or affecting the opposite side, as opposed to ipsilateral
Coronary Circulation
Movement of blood through the coronary vessels supplying tissues of the heart
Enocarditis
Inflammation or infection of the inner lining of the heart (endocardium)
Epicardial
Relating to the outermost (on top) layer of the heart wall
Implantable Defibrillator
Implantable device delivering an electrical shock to restore a normal heart rhythm
Infarction
Death of tissue
Intracoronary
Within the heart
Ipsilateral
Situated on, pertaining to, or affecting the same side, as opposed to contralateral
Myocardial
Relating to the myocardium (second layer of the wall of the heart)
Nonselective Catheterization
Catheter placed in the main trunk, contrast may be injected, images may be taken, the catheter is not moved into any other branches
Non-tunneled Catheter
A catheter inserted through the skin directly into a central vessel
Non-tunneled Catheter
A catheter inserted through the skin directly into a central vessel
Occlusion
Closure; the act of closing
Papillary Muscle
Muscles attached to the lower portion of the interior wall of the ventricles and connected to the chordae tendineae
Prolapse
Sinking of an organ or other part
Pulmonary Circulation
Movement of blood from the heart to the lungs and back to the heart again
Purkinje Fibers
Conduction myofibers branching off of the right and left bundle branches into cells of the myocardium
Regurgitation
Flowing backwards
Retrograde
Moving backward or against the usual direction of flow
Revascularization
Reestablishment of blood supply to a part
Selective Catheterization
Catheter placed in branches further off the main trunk (first, second, third or higher order)
Sinoatrial
Refers to the sinus of the venae cavae of the mature heart and the right atrium
Stenosis
Narrowing, stricture
Subendocardial
Under or below enocardium
Syncope
Loss of consciousness and postural tone
Systemic Circulation
Supplies nourishment to tissue located throughout the body with the exception of the heart and lungs
Thrombolysis
Destruction of blood clot
Transluminal
Destruction of a blood clot
Transluminal
Through or across the lumen (tube) of an artery or vein
Tranvenous
Through or across a vein
Trifurcation
Division into three branches or parts
Tunneled Catheter
Catheter tunneled through the skin and subcutaneous tissue to a central vessel. The entrance point of the catheter is distant from the entrance to the vascular system
Valvular Prolapse
Valve leaflets fall backward into the heart chamber
Valvuloplasty
Surgical reconstruction of a valve
Ventricle
Lower chamber of the heart; right ventricle left ventricle.
Epicardium
or visceral pericardium covers the heart’s surface and extends to the great vessel
Myocardium
the contracting muscle of the heart and consists of striated muscle fibers interlaced into bundles
Innermost endocadium
composed of thing layer of endothelium and thin layer of connective tissue
Atria, Atrium
Holding tanks in upper heart chamber holding tanks and receive blood as it comes into the heart
Ventricles
lower chambers of heart that pump blood out
Atrioventricles
AV valves open from atria to ventricles
Hypertension
HTN High Blood pressure, chronic condition in which the blood pressure in the arteries is elevated. Hypertension and Heart Disease or Chronic Kidney Disease are combo codes unless doctor specifies they are unrelated
Primary Hypertension
High blood pressure for which no medical cause can be found
Secondary Hypertenstion
Caused by conditions affecting kidneys, arteries, heart or endocrine system
Myocardial Infarction
MI or Heart Attack. A blockage of blood flow to the heart muscle
STEMI
In heart attack or MI the coronary artery is completely blocked
NSTEMI
in heart attack or MI the coronary artery is partially blocked
Arteriosclerosis
Hardening of the arteries
Angina
A type of chest pain caused by reduced blood flow to the heart.
Angina is a symptom of coronary artery disease.
Angina feels like squeezing, pressure, heaviness, tightness, or pain in the chest. It can be sudden or recur over time.
Ischemia
restriction in blood supply to tissues, causing a shortage of oxygen that is needed for cellular metabolism (to keep tissue alive).q
