Angiography | Radiographic visualization of blood vessels following introduction of contrast material. |
Angioplasty | Procedure to open narrow or blocked vessels. |
Antegrade | Moving or extending anteriorly, moving with usual direction of flow. |
Arrhythmia | Irregularity of heart rate or rhythm, loss of rhythm. |
Arteriosclerosis | Hardening of the arteries. |
Atherectomy | Procedure to remove plaque from arteries. |
Atherosclerosis | Build up of plaque on artery walls. |
Atria | Upper chambers of the heart; right atrium, left atrium. |
Atrioventricular (AV) | Relating to both the atria and the ventricles of the heart. |
Bifurcation | Division into two branches. |
Bundle of His (AV Bundle) | Muscle fibers in the heart's conduction system branching off the right and left sides of the heart. |
Capillaries | Smallest branches and 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. |
Conduction System | Generates and distributes electrical impulses over the heart and along the septum to stimulate contraction, allowing blood to move through the body. |
Contralateral | Situated on, pertaining to, or affecting the opposite side, as opposed to the ipsilateral. |
Coronary Circulation | Movement of blood through coronary vessels supplying tissues of the heart. |
Endocarditis | Inflammation of 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 great vessel. |
Occlusion | Closure; the act of closing. |
Papillary Muscles | Muscles attached to the lower portion of interior wall of the ventricles and connected to chordae tendinae. |
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 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). |
Sinoartrial | Refers to the sinus of the venae cavae of the mature heart, and the right atrium. |
Stenosis | Narrowing, stricture |
Subendocardial | Under or below the endocardium. |
Syncope | Loss of consciousness and postural tone. |
Systemic Circulation | Supplies nourishment to tissue located throughout the body, with exception of the heart and lungs. |
Thrombolysis | Destruction of a blood clot. |
Transluminal | Through or across the lumen (tube) of an artery or vein. |
Transvenous | 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. |
Valvulooplasty | Surgical reconstruction of a valve. |
Ventricle | Lower chamber of the heart; right ventricle, left ventricle. |
