UPDATE|GRADED A+
Question 1
The M-mode echo demonstrates multiple echo within the root. The aortic valve excursion
as determined by 2D is 7 mm. On physical exam, a crescendo-decrescendo systolic ejection
murmur and diastolic decrescendo murmur were heard. The most likely diagnosis is aortic
valve:
A. AI
B. AS
C. AS and AI
D. AS and MS
CORRECT ANSWER
C.
Crescendo-decrescendo systolic = AS
Decrescendo diastolic murmur = AI

D. Post-stenotic dilation of desc. AO
CORRECT ANSWER
1
, D.
Question 3

A. Greater than or equal to 14 mm
B. Less than or equal to 12 mm
C. Less than or equal to 10 mm
D. Less than or equal to 8 mm
CORRECT ANSWER
D.
Question 4
Cardiac Doppler parameters used to assess the severity of valvular AS include all EXCEPT:
A. AoV P1/2t
B. AoV Vr
C. Mean PG
D. Peak AoV Vmax
CORRECT ANSWER
A.
Question 5
