Cardiovascular System Flashcards
Angiography
Radiographic visualization of blood vessels following introduction of contrast material.
Anastomosis
Joining of two or more blood vessels
Angioplasty
Procedure to open narrow or blocked vessels
Annuloplasty
Surgical reconstruction of the ring (annulus) of a heart valve
Antegrade
Moving or extending anteriorly, moving with the 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 to the right and left sides of the heart
Capillaries
Smallest branches of arteries and veins
Cardioversion
Use of defibrillator paddles to restore normal rhythm of the heart by electrical shock
Cardioverter-defibrillator
Implantable device delivering an electrical shock to restore a normal heart rhythm
Chordae Tendinea
String-like tendons linking papillary muscles to the tricuspid valve in the right ventricle and the left mitral valve in the ventricle
Conduction 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 coronary vessels supplying tissues of the heart
