Transesophageal Echocardiography (TEE)

Transesophageal Echocardiography (TEE) – provides a high resolution ultrasonic imaging of the posterior structures of the heart (e.g. left atrium, mitral valve and aorta) via the esophagus.

B. Purposes of the Procedure

1. Used to readily diagnose and quantify diseases of the aorta, such as aortic dissection

2. Indicated for defining the source of embolism

3. Atrial tumors and thrombi, patent foramen ovale, and aortic debris can be detected

4. Used to assess presence of vegetations for the diagnosis of infective endocarditis

5. Used during cardiac surgery to guide mitral valve repair and septal myectomy

6. Can evaluate suspected abnormalities of a metal prosthesis.

Transesophageal Echocardiography Findings

C. Nursing Interventions Before TEE

1. Ascertain history of esophageal surgery, malignancy, or allergy to anesthetics or sedatives

2. Nothing per orem for 4-6 hrs before the procedure

3. Encourage to void before the procedure

4. Remove dentures and other oral prosthetics

5. Administer sedatives as ordered

6. Keep suction and resuscitation equipment readily available

7. Cardiac monitoring is done during the entire procedure

8. Place patient in chin-to-chest position to facilitate passage of endoscope

Transesophageal Echocardiography Procedure

D. Nursing Interventions After TEE

1. Nothing per orem until gag reflex returns

2. Place in lateral or semi-Fowler’s position

3. Encourage to cough

4. Throat lozenges or rinses may be used to relieve throat soreness

5. Observe for signs and symptoms of complications, e.g. pharyngeal bleeding, cardiac dysrhythmias, vasovagal reaction, and transient hypoxemia
