Rescue TEE Flashcards
What is the criteria for determining hypovolemia in the transgastric short axis TEE view of the LV in terms of:
- End diastolic diameter?
< 2.5 cm
What is the criteria for determining hypovolemia in the transgastric short axis TEE view of the LV in terms of:
1. End diastolic area?
End diastolic area <55 cm2
What is the normal end-diastolic diameter of the LV in the TEE TG SAX view?
3.7 - 5.3 cm
In the TEE TG SAX view, what defines small amount of pericardial fluid?
< 0.5 cm (100-200) - Small
In the TEE TG SAX view, what defines moderate amount of pericardial fluid?
0.5 cm - 2 cm (200 - 500 mL) Moderate
In the TEE TG SAX view, what defines large amount of pericardial fluid?
>2 cm (>500 mL) Large
What is better for evaluating intrapericardial clot and posterior/loculated effusions?
(TTE vs. TEE)
TEE > TTE
What is a specific sign of pericardial tamponade?
RV Diastolic collapse
Pericardial Pressure >> RV Pressure
What is the sensitivity, specificity and Positive predictive value to atrial compression for cardiac tamponade?
Sensitivity = 95%
Specificity = 82%
PPV.= 50%
What is the Specificity and Sensitivity for detecting pulmonary embolism via TEE?
- Specificity = 95% (If you see thrombus = It’s probably PE)
- Sensitivity = 46% (If you don’t see thrombus, you can’t say it’s not a PE)
What are the associated signs of a PE that can help lean towards a diagnosis of PE if you don’t see a clot?
- Comment on RV
- Chamber sizes
- What’s dilated?
- Comment on the IVC
- Valve changes?
- Specific sign?
- RV Hypokinesis
- RV enlargement
- Small LV
- Flattening of the Intraventricular septum or paradoxical septal motion
- Dilated PA
- Dilated RA
- Distended IVC with loss of respiratory variation
- Tricuspid Insufficiency
- McConnell’s Sign
What is McConnell’s Sign?
What is associated with?
Regional wall motion abnormalities sparing the RV apex
Associated = Massive PE with poor prognosis
McConnell sign better seen on TTE or TEE?
TTE > TEE
What is the basic equation for Blood Pressure?
BP = CO x SVR
BP = HR x SV x SVR
What is stroke volume equal to?
End-Diastolic Area - End-Systolic Area
