Anatomy And Hemodynamic Flashcards
Which valve separates the areas of greatest pressure differences
Mitral valve
LAD lies where?
In the anterior interventricular groove or sulcus
Which aortic leaflet is the superior one in the parasternal long axis view?
RCC leaflet
Which aortic leaflet is the posterior one in the parasternal long axis view?
Noncoronary cusp
From the left parasternal window which of the following are the most likely to get accurate velocity measurements?
Pulmonary artery
Name the tricuspid leaflets
- posterior
- Anterior
- Septal (medial)
Where is the LLA on TTE?
Sometimes in the parasternal SAX aortic valve level (better seen in the apical 2 chamber
The coronary arteries come off the ?
Sinuses of valsalva
During which phase do the coronaries fill?
Early diastole
LVIDd measurement
Male
Female
Male: 4.2-5.8 cm
Female:3.8-5.2cm
LVIDs measurements
Male
Female
Male:2.4-4.0cm
Female: 2.2-3.5cm
SWT measurement
Male:.6-1cm
Female: .5-.9 cm
PWT measurement
Make: .6-1cm
Female: .5-.9cm
LA dimension measurement
Male: 3-4cm
Female: 2.7-3.8cm
LA volume measurement
Male and female: 16-34mL
When do you measure LVIDd
End diastole
-frame after mitral valve closure or frame in the cardiac cycle where the dimension is largest
When to measure LVIDs
End systole
- frame proceeding mitral valve opening. Or the frame when the cardiac dimension is smallest
When do you measure SWT and PWT
End diastole.
- frame proceeding mitral valve closure, or frame in cardiac cycle where the dimension is largest
When do you measure LA dimension and LA volume
End systole
- frame proceeding mitral valve opening or the frame when the cardiac dimension is smallest
When and how do you measure aortic valve annulus
Inner edge to inner edge in mid systole
When and how do you measure AO sinuses, AO sinotubular junction, and ascending AO
Leading edge to leading edge at end diastole
The best images of the ascending aorta are often obtain in which transducer window
Suprasternal
Name the vessels coming off the arch and most proximal or distal
- Innoninate
- Left carotid artery
- Left subclavian artery
What cardiac pathology is associated with bicuspid AOV
Coarctation of the aorta
Where do most aortic coarctations occur
After the take off if the left subclavian artery or within the aortic isthmus
From the apical 4 chamber view how do you rotate the transducer to obtain the apical LAX
Counterclockwise 120
Where is the coronary sinus located
Posterior AV groove
To visualize the coronary sinus in the apical 4 chamber view you should tilt the transducer how
Posterior
Which valve sits at the opening of the coronary sinus
Thebesian
What portion of the pulmonary venous PW Doppler represents atrial systole
A wave
