With inspiration: R side
murmurs increase, L side
decrease.
With standing: HCM and MVP
get louder.
With squatting or passive leg
raising: HCM and MVP
become softer and delayed.

Localized >50% diameter increase involving all three
layers of the wall.
Risk factors: Age>60 years, smoking, HTN, dyslipidemia,
family history. If younger, think of Marfan, Ehler-Danlos ,
syphilis, Takayasu’s, trauma, bicuspid valve, aortic
coartation.
Most common in men, 3:1; infrarenal, mostly
asymptomatic, can present with compression symptoms,
distal embolism or rupture.
Surgery if growth more than 0.5cm/year, abdominal >55
mm in men, >45mm in women, ascending aortic >50mm,
and descending >60mm.
Patients with >45mm should have f/u 3 months.
Percutaneous repair is possible for infrarenal.
After surgery, evaluate every 6 months with CT or MRI.

valve, collagen disorders-Marfan, Ehlers Danlos-, aortic coartation.
In older than 70years: HTN, diabetes, vasculitis and preexisting
aortic aneurysm.

Stanford A: Ascending aorta. 2:1. Involves aortic arch in 30%, worse
prognosis, surgical emergency. Mortality with surgery 10-30% and
without 50%.
Stanford B: The rest of aorta. Mortality with medical management
10% per year or better. Surgery if occlusion of major branch,
extension of dissection, Marfan. TX: BB, SBP 100-120, avoid

Question

A diabetic patient has chest pain. Because of
anterior wall MI with ST elevation, TPA and
lovenox are started. Within 30min patient is
feeling better ST-T segment came back to
baseline but tele shows wide complex, NSVT.

A patient with known hypertension, with no past
h/o MI is admitted to CCU with a large Q-wave
acute anterior MI. On the third day he is
suddenly found in shock without any pulse or
