Figure Multimodal imaging and pathological findings.
A and B Transthoracic echocardiography showing a dissecting
aneurysm of the sinus of Valsalva involving the interventricular septum.C The two-dimensional and color Doppler comparative focused
images of the parasternal long-axis view of the aortic root show
low-speed shunting through the ruptured flow into the aneurysm (white
arrows). D Three dimensional echocardiography image viewed from
the aortic root, showing intimal tears in the sinus (dotted line).E Computed tomography angiography showing a large aneurysm
arising from the sinus of Valsalva. F and G Light microscopy
examination of the aortic aneurysm showing
focal thickening of the arterial
intima with fibrous tissue hyperplasia and multiple focal destruction of
the medial structure of the artery with chronic infiltration of
inflammatory cells, primarily plasma cells ( H&E ×25, ×200,
respectively). LV, left ventricle; LA, left atrium; RV, right ventricle;
RA, right atrium; AV, aortic valve; Ao, aorta; IVS, interventricular
septum; PA, pulmonary artery; Aneu, aneurysm.
