What does dilation mean?
Enlarged
What does aortic ectasia mean?2
- Enlarged, tortuous.
- Larger than normal, but not yet aneurysmal
What does aortic aneurysm look like? (Think of how it looks like on U/S) 2
- Saccular or diffuse
- > 150% of normal size
With dilation what happens with the sino-tubular junction?
Loss of sino-tubular junction with most types of dilation
What is dilated sino-tubular junction associated with?6 (Disease)
- Marfan syndrome
- Inflammation disease such as
- Hypertension
- Trauma
- Infection
- Takayasu arteritis
What inflammatory diseases are associated with Sino-Tubular Dilation?2
- Rheumatoid arthritis
- Ankylosing spondylitis
What are some complications of aortic aneurysms?3 (what could happen)
- Rupture
- Dissection
- Aortic regurgitation
What does a rupture of the aortic aneurysm look like?
Wind sock appearance
Why do we see aortic regurgitation with aortic aneurysm?
Dilated annulus
What do we need to determine with aortic aneurysms? 3
- Size
- Site
- Severity of AI
What kind of disorder is Marfan’s syndrome?
Connective tissue disorder
What are some physical features of Marfan syndrome? 3
- Skeletal
- Ophthalmic
- Cardiac
How does someone get Marfan syndrome?
Inheritied
What doe we see in the heart with Marfan syndrome?
Dilatation of the root separates the cusps and leads to valve incompetence
Where does sinus of valsalva aneurysms arise from?
arise in one of the Coronary sinuses
How common is sinus of valsalva aneurysms?
Rare congenital anomaly
What is sinus of valsalva aneurysms associated with?
Bicuspid AV, VSD
What do we look for with S of V aneurysms with echo? 4
- Type
- Location
- Size
- Associated abnormalities
What is takayasu’s arteritis? 3
Disease of arterial scarring resulting in multiple
1. Localized aneurysms/ narrowing’s
2. Post stenotic dilatation
3. Calcification of the aorta and its major branches
What are some clinical signs of Takayasu’s Arteritis? (who’s affected) 4
- Female
- 15-30 years
- Asian descent
- Pulseless upper extremities
What are some echo findings of Takayasu’s arteritis? 3
- Ao/Ao root dilatation
- Possible myocarditis
- Large vessel stenosis
What is a aortic dissection?
Intima tears away from the media
What is almost always associated with aneurysm?
Aortic dissection
What is the etiology of aortic dissection? 6
- Genetic conditions
- Bicuspid AV
- Hypertension
- Atherosclerosis
- Pregnancy
- Trauma
What are some clinical signs of Aortic dissection? 4
- Dizziness/ syncope
- Chest pain
- Neck pain
- Occlusive arterial signs
What are 6 potential complications of aortic dissection? 6
- Asc Ao dilatation
- Acute severe aortic regurgitation
- Pericardial effusion
- Coronary vessel occlusion + wall motion abnormalities
- Distal vessel obstruction
- Aortic rupture
What do we need to assess for with aortic dissection? 3
- Flap
- Dilated Ao
- True and false lumen color flow patterns
What are some tips for TTE imaging for Aortic dissection? 4
- Differentiate artifact from flap
- Always scan at a higher interspace than PLAX to see the Asc. Aorta on every patient
- Measure diameters perpendicular to the vessel
- Assess for coronary artery occlusion (RWMA) when dissection is identified
How do we differentiate artifact from the flap with TTE?(In terms of TEE imaging for aortic dissection?) 2
- Reverb artifact and LT innom vein may both imitate a flap
- If you cannot definitively say that the echoes are artifact, than you cannot rule out a dissection
What is a Aortic intramural Hematoma?
Variant of aortic dissection with a localized collection of blood within the aortic wall
10-15% of aortic intramural hematoma progress to what?
Frank dissection
How does the aortic intramural hematoma usually appear?
As a crescent shaped mass within the aortic lumen
What is a coarctation of the aorta?
A congenital luminal narrowing of the aorta due to a posterior shelf
Where is the location of a coarctation of the Aorta?3
Aortic isthmus between subcl A and 1st intercostal A
1. Preductal
2. Ductal
3. Post ductal
What is PA and RVOT dilatation?
Pulmonary artery pathology less common than aortic
PA and RVOT dilation may dilate with what? 3
- Pulmonary hypertension
- Pulmonary Stenosis
- Congenital
What are some non-congenital causes of dilated PA? 3
- Right sided volume overload, significant LT>RT shunt
- Pulmonary hypertension
- Idiopathic dilation of the pulmonary artery
What are some non-congenital pulmonary hypertension issues that lead to dilated PA? 5
- COPD
- Right heart failure
- Left heart failure
- Mitral stenosis
- Severe mitral regurgitation
