septal\nPosterior can only be seen in RVIT plax
4. The coronary Arteries come off the? \n - ANSWER Sinuses of Valsalva

6. The formula for calculating EF is: \n - ANSWER EDV-ESV / EDV x 100
7. Stroke Volume \n - ANSWER EDV-ESV
8. The LA dimension is measured on M=mode during? \n - ANSWER End -
systole
9. Where are the pulmonary veins located? \n - ANSWER Can be seen in
Apical 4 chamber w/inferior angulation.
10.How do you bring in the RVIT in PLAX? \n - ANSWER Angle Medial and
Inferior from Aortic Root. TV
1
,11.How do you bring in the RVOT in PLAX? \n - ANSWER Angle Lateral and
Superior from Aortic root. PV
12.Where is the Chiari Network located? \n - ANSWER RA
13.Where is the aortic isthmus located? \n - ANSWER Area between the left
subclavian and the ductus arteriosus(where most coarctations occur)Sinus of
Valsalva is the most common area of dissections).
14.The ____ is the most anterior chamber of the heart? \n - ANSWER RV
15.Pulmonary artery is _____, _____ \n - ANSWER anterior, superior
16.The Eustachian valve is located in the? \n - ANSWER IVC
17.Can you see the moderator band in the PLAX? \n - ANSWER No-
Moderator band is located in the RV
18.Where does the moderator band extend? \n - ANSWER From the lower
intraventricular septum to the anterior wall where it joins the papillary
muscle.
19.Spontaneous chordal rupture more often occurs on which leaflet of the
Mitral Valve? \n - ANSWER Posterior \nAlso psterior medial papillary
muscle \nSingle blood supply to posterior wall
20.The heart tube normally loops? \n - ANSWER Anterior and to the right
21.Where is the coronary sinus located in relation to the descending aorta \n -
ANSWER The coronary sinus is located anterior to the descending aorta. If
the coronary sinus is dilated, it can be mistaken for the descending aorta.
22.How would you angle to view the coronary sinus in the apical four chamber
view? \n - ANSWER From the apical four chamber you you would angle
inferior in order to visualize the coronary sinus, which is located posterior to
the mitral annulus.
23.Why is it important to know the location of the coronary sinus and the
descending aorta? \n - ANSWER Pericardial Effusions lie posterior to the
2
, coronary sinus and anterior to the descending aorta. \nPleural effusions lie
posterior to the descending aorta.
24.What is another name for the RVOT? \n - ANSWER Infundibulum
25.Where is the coronary sinus located in the parasternal long axis view? \n -
ANSWER The coronary sinus lies in the posterior AV groove. This groove
is located between the LA and LV walls and lies posterior to be MV. In the
parasternal long axis view, the coronary sinus can sometimes be seen as a
small echo free circle.
26.What would cause the coronary sinus to become dilated? \n - ANSWER The
coronary sinus dialates due to increased pressure in the RA, increased flow
to coronary sinus.
27.Describe the anatomy of the tricuspid valve, including the name and location
if each leaflet. \n - ANSWER Location is between the Right atria and right
ventricle. It has three leaflets: anterior, posterior, and medial or (septal)
leaflets. \nThe names reflect the anatomical relationship to the right
ventricle. The medial leaflet is connected to the septal wall. It's insertion is
located closer to the cardiac apex than that of the anterior mitral valve
leaflet.
28.Name and describe two main layers of the pericardium? \n - ANSWER
Often referred to as 2 main layers as visceral and parietal. This visceral layer
lies directly upon external surface of the heart and is commonly referred as
the epicardium. The parietal or fibrous pericardium is the thick outer sac.
Pericardial cavity lies between the two layers.Anatomically 3 layers are:
serous visceral, serous parietal, fibrous pericardium.
29.Name the three major coronary arteries. \n - ANSWER The three major
coronary arteries are the right, left ant descending (LAD), and the circumflex
arteries
30.The heart tube loops _______ at day ____ \n - ANSWER The heart tube
loops ANTERIORLY and RIGHTWARD at day 22
31.The AV canal is a large communication between the __________ and
________ \n - ANSWER Primitive atria and primitive ventricle
3
, 32.The ________ divides the AV canal into right and left AV orifices \n -
ANSWER Endocardial cushions
33.The ductus arteriosus closes after birth due to increased systemic pressure
and becomes the _______ \n - ANSWER Ligamentum arteriosum
34.What are the two Right to Left shunts in the normal fetal circulation? \n -
ANSWER Foreman ovale\nDuctus arteriosus
35.Following electrical depolarization of the myocardial cell membrane, which
ion rushes in first and which ion rushes in later? - ANSWER Sodium is a
rest \n\n* Calcium is 2nd and responsible for contraction
36.\nWhere is a subaortic membrane (DSS) located? - ANSWER just below the
Aortic Valve
37.Tricuspid Valve leaflets seen in the PSAX-Aortic valve - ANSWER Medial
(septal)\nAnterior
38.Name the cardiac walls supplied by each of the coronary arteries. -
ANSWER right coronary artery \na) inferior wall \nb) inferoseptal \nc) right
ventricular apex \nd) right ventricular free wall. \n**RIGHT= inferior,
septals, right
39.Left anterior descending artery - LAD - ANSWER a) anterior wall \nb)
anteroseptal \nc) left ventricular apex \n**LEFT = anterior, apical, left
40.Circumflex artery - ANSWER a) anterior lateral wall \nb) inferolateral wall\
nCIRC = laterals
41.What walls do the LAD supply? - ANSWER Anterior IVS, Anterior Left
Ventricle and Apex
42.What walls do the CX supply? - ANSWER Anterolateral and inferolateral
43.\n\nWhat walls do the Posterior descending artery supply? - ANSWER
