RF for patient populations for anyeursm
- Marfans
- Erlos-Danlos
- BAV
- turner’s
- coarctation of the aorta
which lab test rules out dissection
d-dimer < 500
imaging for dissection
CT/MRI if stable
unstable - CT or TTE/TEE
medical tx dissection
Type A- root - surgery
Type B - medical therapy
- IV BB (keep BP < 120), + IV nitroprusside to keep HR < 60-70
referral to thoracic/ abdominal surgery anyeursm
- > 5.5 cm
- > 0.5 cm every 6 months
- symptoms of compression
murmur for dissection
- low pitch diastolic murmur for aortic regurgitation
2. or crescnedo-decrescendo systolic murmor of BAV
acquired inflammation of aortic root
- Syphillis
- Takayasu
- giant cell
who should be considered to 5.0 cm thoracic root
- Marfan
- women considered pregnancy
- BAV
AAA screening
one-time ultrasonographic screening in men aged 65 to 75 years who are active or former smokers
TX AAA ANYEURMS
Elective repair should be considered for AAA of 5.5 cm in diameter, for those that increase in diameter by more than 0.5 cm within a 6-month interval, and for those that are symptomatic (tenderness or abdominal or back pain).
if AAA is big, how often
> 4.0, then annually
surveillance AAA in Marfan’s
American College of Cardiology Foundation/American Heart Association guidelines recommend follow-up imaging 6 months after diagnosis, with annual surveillance thereafter if the aortic root is less than 4.5 cm in diameter and otherwise stable.

surgical indications for endocarditis
- Heart failure
- Left sided with fungal or highly resistant organism
- heart block/abscess/destructive penetrating
- persistent infection 5-7 days on abx
- recurrent phenomoni despite abx
- prothestic valve
patients requiring prophylactic abx for endocardiats
- prostethic valve
- Congenital heart disease, cyanotic or repaired with residual shunts
- previous hx of endocarditis
- cardiac transplant with valve issues
which procedures required prophylactic
dental
abx used for prophylaxis endocarditis
Amox/amp or clinda (pen allergic)
medication timing in type b aortic dissection
IV BB (labetolol or esmolol) should be given first and if the SBP remains above 120 then nitroprusside shoudl be added. Don't do nitroprusside first because of the risk of reflex tachycardia
