Moderate aortic stenosis – Cardiology MCQ – Answer
Moderate aortic stenosis – Cardiology MCQ
Mean pressure gradient across the aortic valve in moderate aortic stenosis is between:
Correct answer: 1. 20-39 mm Hg
In addition a peak aortic velocity between 3.0 to 3.9 also qualifies for moderate aortic stenosis. Severe aortic stenosis has a mean transvalvar gradient of 40 mm Hg or more. Peak aortic velocity in severe aortic stenosis is taken as 4 m/s or more. In case of low flow, low gradient severe aortic stenosis, valve area below 1 sq cm is the cut off value.
