leaflet
 
thin, flattened structures that compose a heart valve
lumen
 
the channel within a tubular space within an organ or structure

localized abnormal dialation of a vessel, usually an artery

angi/o
vascul/o
 
vessel, usually blood or lymph

septum

sphygm/o
--sphyxia
 
pulse

sten/o
--stenosis
 
narrowing, stricture

fibrillation
 
quivering or spontaneous muscle contractions, especially of the heart, causing ineffectual contractions
endo--
 
in, within
extra--
 
outside
arrest
 
condition of being stopped, or bringing to a stop
bruit
 

soft blowing sound heard on auscultation
also called a murmur
cardiomyopathy
 
any disease or weakening of heart muscle that dimishes cardiac function
catheter
 

plastic tube that is small enough to be threaded through a vein, artery, or tubular structure
(thin, hollow, flexible)
coarctation
 
narrowing of a vessel, especially the aorta
DVT-deep vein thrombosis
 
blood clot that forms in the deep veins of the body, especially those in the legs or thighs
vegetations
 
small inflammatory mass on leaflets

HTN-hypertension
primary
secondary
 

BP persistently exceeding 140/90
no identifiable cause
identifiable, underlying cause commonly correctable
manometer
 
device used to measure pulse
hemostasis
 
arrest of bleeding or circulation
hyperlipidemia
 
excessive amounts of lipids in the blood (cholesterol, phospholipids, and triglycerides)
infarct
 
area of tissue that undergoes necrosis following seccation of blood supply
ischemia
 
local and temporary deficiency of blood supply due to circulatory obstruction
MVP-mitral valve prolapse
 
condition in which the the leaflets of the mitral valve prolapse into the left atruim during systole causing a characteristic murmur

ICU
CCU
 

intensive care unit
coronary care unit
systole/diastole
 
top/bottom BP
perfusion
 
circulation of blood through tissues or the passage of fluids through vessels of an organ
paroxysm
 

spasm pertaining to the heart
sclerosis
 
hardening
diaphoresis
 
excessive sweating
--rrhexis
 
rupture
angioplasty
 
replacement of artery
antihypertensive medications
 
lower blood pressure-such as beta blockers and calcium channel blockers

diuretics
 

lower fluid within the body
antianginal medications
 
dialate blood vessels-nitrates (nitroglycerin)

cardiotonic medications
 

raise the force of contractions to maintain slow and steady heart rate
asystole
 
flat line, no pulse or beat
CVA
 
cerebrovascular accident-stroke
incompetent
 
inability of a valve to close completely
varices
 
varicose veins of the esophogus
infarct
 
area of tissue that undergoes necrosis
