|
Bernoulli equation for calculating transvalvular pressure
|
Delta p = 4v^2
v=velocity of flow Delta p= pressure gradient across two chambers |
|
|
|
Inspiration increases venous return to the R heart. What happens to R heart sounds?
|
get louder EXCEPT PULMONIC EJECTION
|
Incr venous return -->
incr RV vol across pul stenosis--> pulm ejection sound (soft) b/c the valve begins to open up from a higher starting position in early systole = less distance for the valve to travel before tensing |
|
|
Heart sound for pulmonary HTN?
|
wide split 2nd heart sound (P2)
|
|
|
|
Concave up ST elevation is associated w/ what disease?
What is the treatment? |
Pericarditis;
NSAIDS |
|
|
|
What is the treatment for acute MI with low EF?
|
Radionucleotide ventriculogram (MUGA) = ECHO
If the EF<30%, this is indication for |
Coronary angiography
|
|
|
Atypical chest pain w/o evidence of ischemia on EKG/labs. Next step in management?
|
1. Admit to the hospital for probably ACS
2. Start ASA, Plavix & LMWH |
|
|
|
What two fibrinolytics are shown to have more favorable mortality?
|
tPA & LMWH (GUSTO trial)
|
lower 30-day mortality
|
|
|
Appropriate mgmt immediately after a defibrillator shock?
|
Resume CPR for 2 min.
(5 cycles of 30 compressions & 2 breaths) -w/o stopping to assess rhythm |
|
|
|
Claudication in butt & hip, decr femoral pulses & ED (Leriche Syndrome) suggests atherosclerosis in what arteries?
|
Aorto-iliac
|
|
|
|
RV/parasternal impulses, fixed splittig S2, sys pulm flow murmur, R-sided cardiac chamber big
*RAD & RBBB |
ostium secundum ASD
|
|
|
|
Young patient w/ DOE for 2 yrs but no Si/Sx/tests show DVT, PE or sleep apnea. TTE w/ Pulm HTN. What is the next test?
|
Right Heart Cath (measures MAP directly)
|
|
|
|
Inability to move a limb, no feeling in it, no pulse present on Doppler, cool and pale...what's the next step in management?
|
Surgical amputation NOW! (The limb is dead. non ischemic viable limb)
|
|
|
|
For Asx SEVERE aortic stenosis, do you replace the valve?
|
NO
-only replace if (1) Sx (2) exercise induced hypotension or sx, (3) LVEF <60%, or (4) rapidly progressive aortic stenosis (mean gradient >60%) |
|
|
|
Patient reports exertional leg heaviness. She has an ABI>1.40. What's the next step in evaluation?
|
Great toe measurement
(An ABI above 1.40 suggests noncompressible vessels, which may reflect medial calcification but is not diagnostic of flow-limiting atherosclerotic disease.Vessels within the great toe rarely become noncompressible, and a great toe systolic pressure below 40 mm Hg or a toe-brachial index of less than 0.70 is consistent with PAD.) |
|
|
|
What is the ABI (ankle brachial index)?
|
The DP/PT pulse (highest for each side) divided by the highest Brachial pulse.
**ABI<0.90 = PAD |
|
|
|
Patient w/ exertional chest pain and dyspnea with prior radiation to the chest is at risk for what valve d/o? Patient has no signs of R heart failture.
|
Aortic regurg
|
