APICAL 4 ANATOMY
IVS,RV,TV,RA,IAS,LV,LW,MV,LA
most posterior chamber of the heart
LA
APICAL 2 ANATOMY
LV,IW,AW,MV,CS,LA
Where is the Chiari Network located?
RA
what cardiac chamber has the lowest pressure?
RA
what cusps of the AOV are seen in the PSLA?
RCC and NCC
most anterior chamber of the heart
RV
where is the moderator band located?
RV and extends from lower IVS to anterior wall where it joins the pap muscle
RVOT ANATOMY
RV, PV, MPA
dyskinetic
abnormal, walls moving in the same direction
cardiac output
amount of blood ejected by the ventricle during a 1 minute interval
sonographically how do the four chambers of the heart appear?
anechoic
what is the supraventricularis?
another name for RVOT
what are the semilunar valves?
aortic and pulmonic
what do we evaluate in subcostal 4?
assessing IAS for ASD, evaluate areas around the heart for pericardial effusion, tumors and masses
where is the sinus of valsalva located?
behind aortic valve
where is isovolumic contraction located on the wiggers diagram?
between B and C
where is isovolumic relaxation located on the wiggers diagram?
between E and F
coarctation of the aorta
congenital cardiac condition characterized by a narrowing of the aorta
cardiac tamponade
evaluation of intrapericardial pressure due to accumulation of pericardial effusion which results in an evaluation and equalization of intracardiac pressures, progressive limitations of ventricular diastolic filling and reduced stroke volume
hyperkinetic
fast movement
fossa ovalis
foramen ovale
S4
fourth heart sound
pericardial sac
heart enclosed in a fluid filled sac, prevents friction as the heart beats
what is it called when walls are thickened?
hypertrophy
conus arteriosus
infundibulum (RVOT)
preload
load/volume/pressure exerted on the ventricle at the end of diastole. DETERMINES THE FORCE OF CONTRACTION
pulmonary artery wedge
measurement that represents pressure in the LA
what is the functioning layer of the heart?
myocardium
akinetic
no wall motion
ejection fraction
percentage of blood ejected from the ventricle during systole (per beat)
what is the brightest (hyperechoic) structure we see in the heart?
pericardium
what transducer do you use for an echo?
phased array transducer
what does the moderator band do?
prevents over expansion
isovolumic contraction
represents time period between AV valve closure and semilunar valve opening. All cardiac valves are closed as ventricles begin to contract. Increase in ventricular pressure with no change in ventricular volume.
isovolumic relaxation
represents time period between semilunar valve closure and atrioventricular valve opening. Semilunar and AV valves are closed.
afterload
resistance against which the ventricles must pump when ejecting blood
how do you obtain the subcostal short axis view?
rotate index 90 degrees from subcostal 4 towards patients head or 12:00. Angle beam inferior you will see the IVC as it enters the RA.
Thebesian valve
rudimentary valve formed by a flap of tissue that protects the entrance of the CS
Eustachian valve
rudimentary valve formed by a tissue fold that protects the entrance of the IVC
S2
second heart sound
Where do the coronary arteries originate?
sinus of valsalva
hypokinetic
slow movement
what view do you see coarctation of the aorta in?
suprasternal long axis view
S1
the first heart sound, heard when the atrioventricular (mitral and tricuspid) valves close
S3
third heart sound
what are the atrioventricular valves?
tricuspid and mitral (bicuspid)
Subcostal Short Axis View
view is useful in looking for dilated IVC as in enters the RA.
paradoxical
wall moves in opposite direction
