Ch 3 Disease of Great Arteries Flashcards
What can interfere with the integrity of the elastic + muscular components of the medial layer of the aorta?
Marfan’s syndrome
Aortic root dimensions are based on body surface area + age? True or False
True
What U/S artifacts may be mistaken for an aortic dissection?
Beam width artifact + reverberation
List 3 possible complications of an aortic dissection?
-Acute aortic regurgitation
-Wall motion abnormality
-Pericardial tamponade + effusion
(not acute mitral stenosis)
Which surgical procedure involves replacing the aortic root, aortic valve + ascending aorta?
Bentall procedure
Which layer of the aorta is delicate + easily traumatized?
Intima
Which type of aortic dissection is only contained in the descending aorta (DeBakey classification)?
Type 3
List 4 echo criteria for diagnosis of aortic dissection?
-False lumen
-Pericardial effusion
-An intimal flap within the aorta
-Increase in aortic dimension
(not decrease in Ao dimension)
Tearing of the aorta most often occurs where?
Ascending aorta
Which surgical procedure replaces the aorta + preserves the native aortic valve?
David procedure
Pt’s with bicuspid AoV disease have an increased risk for progressive dilation + dissection of the Ao. T/F?
True
To interrogate for a type 1 Ao dissection, which echo view will be most helpful?
All of the above:
-HPLAX
-SSN
-SUB abdo Ao
(type 1: asc, desc + abdo Ao)
Which of the follow is an echo feature of Ao dissection?
Linear, mobile echogenic structure within the Ao lumen with a pattern of motion different from that of the Ao wall
(not all of the above)
A pt with known Marfan’s syndrome comes in for an echo to monitor their progressive dilation of the AoR + asc Ao. Which of the following is correct when performing measurements?
The AoR + asc Ao are measured at end diastole from leading to leading edge
