Card Set Information
TEE & Embolism Source
List the 4 types of TEE transducers:
Which is most often used?
3. Multiplane (most used)
The multiplane transducer is a steerable array and rotates from 0-180 degrees:
The 5 transducer positions are:
The 4 standard TEE imaging views are:
2. 4 chamber
Can you think of some reasons why a Dr. would choose to do a TEE?
Source of embolism
Rt heart function
When shouldn't you do a TEE?
Esophageal (tumors, stenosis, stricture, etc
Mechanical complications of TEE?
probe buckling, compression of surrounding structures
TEE procedure complications?
Patient intolerance, sore throat
List the 2 classifications of emboli?
What is spontaneous echo contrast?
Dynamic echoes with LA & LAA which resembles swirling smoke
What is A fib? How does it affect the heart?
Cardiac rhythm disturbance (4 E wave with absent A wave)
Thromboembolism is a consequence
Why TEE not used to assess AO stenosis?
B/c of angle, etc. Transthoracic is still better
TEE is not useful for: apex, arch b/c trachea, AS
What is the treatment for A-fib?
Cardioversion, antiarrhytmic drugs, anticoag therapy
Direct source embolism has a _________________ probability of causing a stroke. Some examples of it are: 4
thrombus, tumor, veg, AO atheroma
Indirect source has a __________________ probability of causing a stroke. Some examples of it are: (4)
dilated CMO, ASD, PFO, spontaneous echo contrast
pathological hardening and thickening of tissue
Some echo signs of a pulmonary emboli would be: (5)
Dilated Rt heart chambers
Small LV cavity
Paradoxical septal motion
vis of thrombi in pulmonary arteries
What is the most common cardiac rhythm disturbance?
