B

Aortic Jet Velocity < 4 m/s or Mean Gradient ≥ 40 HG and Aortic Valve Area ≥ 0.8 cm2

C

Aortic Jet Velocity > 4 m/s or Mean Gradient ≤ 35 HG and Aortic Valve Area ≥ 1.0 cm2

D

Aortic Jet Velocity < 4 m/s or Mean Gradient ≥ 35 HG and Aortic Valve Area ≥ 0.6 cm2

Question 1/8

2. According to the 2020 ACC/AHA guideline what is the hemodynamic definition of Stage D2 - symptomatic severe low-flow, low-gradient aortic stenosis (AS) with reduced LVEF?

Question 5/8

6. What are the three factors that favor TAVR to SAVR for aortic valve replacement in the ACC/AHA guideline?

C

Severe CAD, mobility issues of patient, previous chest irradiation

D

Aortic dilation, severe calcification of the ascending aorta, severe renal disease

B

TTE Imaging

C

CT Imaging

D

Dobutamine Stress Test

6-12 months

C

12-18 months

D

12-24 months
