Explain the use of transesophageal echocardiography (TEE) in identifying pulmonary vein thrombosis.
Identify emboli as a potential source of cerebral infarction as located with TEE.
Discuss TEE use in comparison to contrast-enhanced computed tomography (CT) for specific conditions of thrombus identification.
What is the usual primary modality used to identify embolism and stroke? A. Radiography or X-ray B. Computed tomography (CT) C. Mammography D. Magnetic resonance imaging (MRI)
What did researchers determine was the primary cause of the thrombus in each case study? A. Previous history of lung cancer B. Previous history of lung lobectomy C. Genetics D. Age of the patients
What are the benefits of using TEE for the evaluation of pulmonary vein (PV) stumps over CT? A. Ability to document flow velocity B. Ability to evaluate in motion or real time C. No radiation or contrast is required D. All of the above
What limitations are mentioned by the researcher that exist when using TEE to evaluate the PV stump? A. Patient comfort B. Patient consent C. The distance of the PV Stump from the esophagus may prevent visualization D. The patient may not tolerate any procedures well enough for documentation
What percentage of reported cerebral infarction cases are without a source? A. Under 10% B. 30-50% C. 35% D. 10-25%
