Two equations for CO
CO = SV x HR
CO = CSA x VTI x HR
SVR equation
(MAP-CVP)/CO • 80

Surveillance Echo for AS based on severity
Generally Mild: 3-5 years Mod: 1-2 years Sev: 6 mos - 1 year
Surveillance echo for MS by severity
Mild, >1.5: 3-5 years Mod, 1-1.4: 1-2 years Sev: 6 mos - 1 year

Based on INR & body weight
- INR 2-4: 25 U/kg
- INR 4-6: 35 U/kg
- INR >6: 50 U/kg
- Max dose 5000 U at 100 Kg body weight
-or-
1000U for any bleed

Indications for ICD in ToF
- LV systolic or diastolic dysfunction
- NSVT
- QRS duration ≥180 msec
- Extensive RV scarring
- Inducible sustained VA at EPS
Parameters for MitraClip suitability
LVEF: 20-50%
LVESD: ≤ 70 mm
PASP: ≤ 70 mm Hg
Cardiac Power Output: - Equation - Abnormal?/interpretation
MAP x CO / 451
< 0.6 is bad, needs MCS
PA Pulsatility Index (PAPi): - Formula - Interpretation/Abnormal?
(sPAP - dPAP) / RAP
~ < 0.9, consider RV support
Mixed Venous Oxygen Saturation and interpretation
> 65 % (normal/high): Isolated distributive shock
< 65% (low): cardiogenic component
Fick Equation with fudge factor
O2 consumption / arteriovenous O2 difference = (125 mL O2/min/m2) / [13.6 x hemoglobin x (O2 saturation – O2 mixed venous saturation)]
* the O2 saturations are as percentages; e.g., 94% = 0.94
Definition of Chronotropic Incompetence on exercise stress test
< 70-80% age predicted maximal HR achieved with exercise
Mostly 80%?
Dx?
Pericardial cyst
Indications for LV aneurysm repair (3)
- HF
- VA’s refractory to antiarrhythmics and ablation
- Recurrent thromboembolism despite OAC
Diagnosis?
LV Pseudoaneurysm
Diagnosis
SAM associated with Stress CM
MI complicated by LVOT obstruction or SAM and MR: - Management
IV fluids Decrease HR and allow for LV filling with ßB … even if rales and mild hypotension
Preferred stress modality in patients with LBBB or RV pacing
Vasodilator stress rMPI or stress echocardiography
Even if they are able to exercise
Aortic Intramural Hematoma:
- CT findings
- Management
- High attenuation, no contrast enhancement
- Similar management to aortic dissection
Describe INTERMACS Classes
- Critical cardiogenic shock, crash and burn; increasing lactic
- Progressive decline; sliding on inotropes
- Stable, but inotrope dependent; dependent stability
- Resting symptoms
- Exertion intolerant
- Exertion limited; no fluid overload, comfortable at rest, fatigues quickly with activity; “walking wounded”
- Advanced NYHA III
Echo findings for prosthetic valve stenosis (4)
- Elevated transvalvular velocity and gradient
- Prolonged (>100 msec) acceleration time
- Reduced effective orifice area (<1 cm2)
- Reduced dimensionless index (<0.3)
If concerns for HIT, which anticoagulant can be used if undergoing PCI?
Bivalirudin
Which anticoagulant is associated with catheter thrombosis?
Fondaparinux
Appropriate follow-up stress in asymptomatic SIHD patient timeline:
- After PCI
- After CABG
- PCI - after 2 years
- CABG - after 5 years
Gold standard for diagnosis of coronary artery spasm
“Spontaneous pain with ST elevation on EKG in the absence of underlying obstructive CAD”
- provocative tests not necessary
Characteristics of patient who would benefit from CCTA: (3)
- Ongoing sx’s + prior normal testing
- Prior inconclusive testing results
- Unable to do stress nuke or stress echo
CCTA not beneficial if high pre-test prob CAD or established CAD

AV block in the setting of STEMI:
- When can you observe
Can observe if inferior MI, otherwise a-sx
Consider other stuff if LAD territory
Indications to PCI spontaneous coronary artery dissection?
