True or False

When the transducer is angled more lateral from the 4C, the aortic valve is visualized.

• True

• False

Answer explanation

Anterior

In 5C you angle the transducer moer anterior from the 4C to open up the

True ro False

According to the ASE, an aortic valve peak velocity < 2.5 m/s with mild thickening and/or calcification indicates aortic stenosis.

• True

• False

Answer explanation

Sclerosis

True or False

Sclerosis is without decreased excursion and stenosis is with decreased excursion

• True

• False

True or False

Aortic sclerosis always leads to aortic stenosis

• True

• False

Answer explanation

Sometimes can lead to aortic stenosis

LVOT peak velocity ___ indicates LVOT obstruction (LVOTO)

• >1 m/s

• >1.7 m/s

• >2 m/s

• <2 m/s

Which statement best describes a LVOTO?

• Early peaking, dagger shaped systolic jet

• Late peaking systolic jet that sounds like a sponge being wrung out

• Rounded, high velocity waveform because there is increased velocity

• Very low velocity waveform because there is decreased flow

How is the 2C acquired?

• Angle more superior and medial from the LAX

• Angle more posterior and lateral from the LAX

• Rotate 60-90 degrees clockwise from the 4C

• Rotate 60-90 degrees counterclockwise from the 4C

True or False

Descending aorta can be seen from the 2C as a separate structure, anterior to the left atrium

• True

• False

Answer explanation

Posterior
