vascular assessment Flashcards

1
Q
  • See extent & severity of cardiac dz in pt w/ symptoms (stable angina)
  • Exclude severe pt in symptomatic pt w/ equivocal (ambiguous) findings on non-invasive studies
  • See if medical, surgical, catheter interventions are needed
  • Plan upcoming surgeries
  • Intervene on known ischemic heart dz (STEMI or NSTEMI)

Q

diff between coronary angiogram and coronary CTA

A

coronary angiogram involves a catheter into the artery and area to be studied, a CT angiogram does not require catheter insertion

16
Q
  • Contrast injected to visualize LV chamber
  • Assess for wall motion abnormalities, aneurysm, pseudoaneurysm or diverticulum
  • Can assess MVP & MR severity
A

ventriculography in L heart cath

17
Q

which procedure is better for

  • Left MAIN dz
  • 3 vessel dz in reduced LVEF or treated DM
  • long lesions >35 mm/diffuse dz
18
Q

stent placement needs ____ or other anticlotting therapy

A

clopidogrel

19
Q

which type of stent has antiproliferative agent that prevents clotting on it

A

drug eluting stents (DES)

20
Q

in pt w/ mild or moderate stable sx (stable angina), ____ & ____ may be preferred initial strategy

A

aggressive lipid & antianginal therapy

21
Q

4 factors associated w/ restenosis after stents

A
  • DM
  • small luminar diameter
  • more complex lesions
  • lesion at coronary ostia or LAD
22
Q

what medication does everyone who gets a stent stay on for life? (2)

A

atorvastatin 80 mg or Rosuvastatin 20mg

high intensity statins

23
Q

minimum duration of dual platelet therapy for pt w/ BMS vs DES

A
  • BMS– 1 month
  • DES– 6-12 mo
24
Q

what meds are used in dual antiplatelet therapy after shunt placement?

A

clopidogrel + aspirin 325 mg

25
if risk of bleeding is low after 12 mo of dual antiplatelet therapy from stent placement, how much longer do you keep them on it?
another 18-24 month (DAPT score)
26
When combined w/ perfusion imaging, can provide assessment of the coronary arteries and the cardiac myocardium in one sitting
coronary CT
27
useful when probability of severe CAD is low to r/o ACS/CAD in setting of chest pain high sensitivity w/ limited specificity-- many lesions that look obstructive on it are non-obstructive on coronary angiography
coronary CT
28
Non ionizing radiation; high resolution dynamic images of myocardium & heart structures can add gadolinium to help assess viability
cardiac MRI
29
continuous ambulatory ECG monitoring for 24-48 hrs; used for daily sx of dizziness, syncope, near syncope, palpitations also to detect silent preoperative ischemia
holter monitoring
30
* Tests heart electrical conduction system to assess electrical activity and conduction pathway * Used to investigate the **cause, location of origin, and ideally tx various arrhythmias** * may ablate cells of origin in abnormal activity
electrophysiology study
31
* evaluation/diagnosis of vasovagal syncope * May include provoked vasodilation (w/ nitroglycerin) * test ends when pt faints, develops other sx or specified time elapses
tilt table testing
32
what is a positive table tilt test (2)
* having sx * drop in BP or arrhythmia
