A 70 year-old non-diabetic otherwise healthy
woman admitted for unstable angina has triple
vessel disease (70% LAD lesion, 70% circumflex, 70%
proximal RCA) and normal LV function. Further
workup included carotid duplex, and this test
reveals an 80% lesion in the right internal carotid
artery. There is no history of CVA or TIA
(asymptomatic carotid lesion).
Would you offer the patient:
QUESTION #1
a. Right carotid stent followed by multi vessel stenting
b. Right carotid stent followed by CABG (staged 2-3 days
later)
c. Right carotid endarterectomy followed immediately by
CABG (concomitant procedure)
d. Right carotid endarterectomy followed by CABG 2-
3 days later (staged)
e. CABG with carotid endarterectomy at a later date

A patient with atrial fibrillation taking dabigatran
(pradaxa) requires non-cardiac surgery.
How do you bridge this patient appropriately?
QUESTION #3
a. Stop dabigatran 5 days prior to surgery and restart 5 days later if taking PO
and recovering well. No bridge with heparin or lovenox.
b. Stop dabigatran 2 days prior to surgery and restart as soon as taking
PO and recovering well. No bridge
c. Do not stop dabigatran
d. Stop dabigatran 2 days prior to surgery, admit to hospital and start IV heparin
first day of no dabigatran, stop heparin drip at midnight prior to surgery,
restart dabigatran as soon as patient is taking PO without more heparin.)
e. Stop dabigatran 5 days prior to surgery, admit to hospital and start IV heparin
first day of no dabigatran, stop heparin drip at midnight prior to surgery,
restart heparin when surgeon says it's OK, restart dabigatran when taking PO
and stop heparin
f. Other
“Ideally would either continue the dabigatran, or need to bridge with
heparin, will depend upon the specific type of surgery”
