NBE Transesophageal Echocardiography 5

Question 1

What is the primary absolute contraindication to TEE probe insertion?

Accepted Answer

Known esophageal stricture or perforation

Answer

Known esophageal pathology such as stricture, perforation, or esophageal varices (class III) represents an absolute contraindication to TEE probe passage.

Question 2

On TEE, systolic anterior motion (SAM) of the mitral valve is most commonly associated with:

Accepted Answer

Hypertrophic obstructive cardiomyopathy

Answer

SAM occurs in hypertrophic obstructive cardiomyopathy when the anterior mitral leaflet is drawn into the LVOT during systole, causing dynamic obstruction.

Question 3

3D TEE is particularly valuable for mitral valve repair planning because it allows:

Accepted Answer

En face 'surgical view' of the mitral valve from the left atrial perspective

Answer

3D TEE provides a 'surgeon's view' en face image of the mitral valve that directly maps to the operative field, improving surgical planning.

Question 4

Which finding on TEE is most consistent with infective endocarditis of the mitral valve?

Accepted Answer

Mobile echodense mass on the atrial side of the posterior leaflet

Answer

Infective endocarditis vegetations are mobile, irregular, echodense masses attached to the low-pressure (atrial) side of the mitral valve.

Question 5

During TEE guidance of a transcatheter mitral valve procedure, which measurement is critical for confirming transseptal puncture location?

Accepted Answer

Height above the mitral annular plane and anterior-posterior position

Answer

Optimal transseptal puncture requires positioning 3.5–4 cm above the mitral annular plane in the superior-posterior fossa ovalis to allow adequate catheter maneuverability.
