Aortic Stenosis.
Image findings:
• In older children or young adults
o Prominent ascending aorta
Poststenotic dilatation of ascending aorta
Due to turbulent flow
o Left ventricular heart configuration
Normal-sized or enlarged left ventricle
Concentric hypertrophy of left ventricle produces a relatively small left ventricular chamber with thick walls
o Heart size is frequently normal
• In adults >30 years
o Prominent ascending aorta
Poststenotic dilatation of ascending aorta
Due to turbulent flow
o Calcification of aortic valve (best seen on RAO)
In females, usually indicates hemodynamically significant aortic stenosis
Calcification of the valve usually indicates a gradient across valve of > 50mm Hg
Calcification begins in bicuspid and rheumatic valve in 4th decade but not until > 65 in tricuspid
66 yo with systolic murmur. What's the most likely diagnosis? See the correct answer at: http://bit.ly/1emBPVw
