|
When would you order a TEE (transesophageal echo) instead of a TTE (transthoracic echo)?
|
To get higher resolution of posterior heart structures (LA, MV, aorta)
|
|
|
What is the biggest dilemma faced when performing Cardiac Catheterization-Contrast Angiography?
What is best use of it? |
The contrast are eliminated renally, so patients with kidney failure/insufficiency cannot tolerate them
- gold standard for anatomy/physiology of heart |
|
|
What does a PET (Positron Emission Test) test for?
|
Assessment of myocardial viability (it lights up if myocardium is ischemic?)
|
|
|
What is the rate of fatality and MI's per stress test?
|
1 fatality per 2500
5 MI's per 10,000 |
|
|
For stress test what are the goals?
|
Target HT 85% of Max H.R.
220‐ age x 85%- Stop if blood pressure falls, heart block, arrhythmias, ST elevation or depression |
|
|
What are absolute contraindications to putting patient on stress test?
|
1. Severe symptomatic aortic stenosis
2. Acute MI within 2-3 days 3. Acute pulmonary embolus 4. Unstable angina (pain at rest despite medicines already on) 5. Uncontrolled arrhythmias with symptoms or hemodynamic compromise 6. Acute stroke 7. Aortic dissection 8. Decompensated heart failure 9. Any active infection in the heart...(Acute endo, peri, and myocarditis) |
|
|
What are big contraindications to Card cath?
|
– Febrile Illness
– Decompensated CHF – Anticoagulated State (PT > 18 Sec) – Renal Insufficiency – Allergy to Contrast |
|
|
What are the two methods to radionuclide imaging?
|
1) Labeling RBC’s with isotope to
assess endocardial motion 2) Perfusion tracers (thallium, sestamibi) to assess differences between resting/stress blood flow |
