21
Q

The 2 chamber view is good for these few thing:

A
  1. Wall motion/Global LV function
  2. Mitral Valve issues
22
Q

This view resembles a “basilisk fang” and is obtained from a bisection of the LV, parallel to the IV septum

A

2 Chamber long axis single oblique

23
Q

This view allows assesment of both mitral and tricuspid valves

A

The Horizonal Long Axis (4 Chamber View)

24
Q

The 4 chamber view is not great for looking at many congenital heart problems, except:

A

AV canal defect

25
What view is this? What is the defect?
4 chamber view Atrioventricular septal defect w ith ostium primum atrial septal defect (arrowhead) and inlet ventricular septal defect (arrow).
26
This is a “down the barrel of polyjuice potion” series of views taken perpendicular to the long axis of the heart.
LV Short Axis view
27
The short axis view is obtained perpendicular to what axis?
4 chamber horizontal long axis
28
What view is this? Identify the structures
29
Other name for the 3 chamber view
Apical LONG axis view
29
This view is obtained by using a short axis view around the mid-base region near the aortic outflow tract
Apical long axis view (3 chamber)
30
What view is this?
3 chamber view
31
The advantage of the 3 chamber view
Visualization of the left ventricular outflow tract (LVOT)
32
Best view to show aortic regurgitation or stenosis?
3 chamber view
33
Descibe the right Atrial enlargement on CXR
Shifting of the right heart border
34
Described the right Ventricle enlargement
Cardiac apex is tilted up and out
35
Describe the left ventricle enlargement
Cardiac apex is tilted DOWN and OUT
36
Indirect signs of left atrial enlargement
Widenening of the carinal angle (>90) Elevation of the left main Bronchus Walking man sign
37
A classic sign describing the posterio displacemnt of the left mainstem bronchus
Walking man sign
38
Identify the lesion
Echogenic focus in the left ventricle
39
What is the Echogenic focus in the Left ventricle? They are associated with what increase of incidence?
Calcified papillary muscle Downs Syndrome
40
DIagnosis?
Lipomatous hypertrophy of the Interarterial Septum
41
dumbbell (bilobed) appearance of fat density in the atrial septum
Lipomatous hypertrophy of the Interarterial Septum
42
What structure is spared in the Lipomatous hypertrophy of the Interarterial Septum
Fossa ovalis
43
Lipomatous hypertrophy of the Interarterial Septum can cause what type of Arythmia?
Supraventricular arrythmia
43
How thick should the atriaul septum be in Lipomatous hypertrophy of the Interarterial Septum?
> 2cm
44
Describe the lipoma in the interatrial septum
Uncommon encapsulated DOES NOT spare the fossa ovalis Rarely associated with arrythmia
