This article by Gilkeson RC et al in the February issue of the AJR, is a pictorial essay on common aortic valvular pathologies as evaluated by MDCT. The article shows some normal anatomy (though a detailed anatomic elaboration of commissure terminology should have been incorporated, as in the other aortic valvular article, reviewed in the last entry) and standard pathologies, such as bicuspid valve, sinus of Valsalva aneurysm, aortic stenosis with calcification, dissection, infective endocarditis and inflammatory aortitis. The pictures are nice. The infective endocarditis pictures were educative, since we've never seen a case, and there was no case illustrating an inflammatory aortitis, which we will show in the next post.
This is a 42-years old man with an aortic root aneurysm. The patient was known to have a bicuspid valve with regurgitation. The cardiac CT study was performed to assess the aneurysm as well as the coronary artery anatomy and to look for possible pathology.
The coronary arterial tree was normal (Fig. 1). The cine images show the bicuspid valve well (cine file transaxial view) with lack of complete closure in diastole on the LVOT cine view, correlating with the regurgitation.
