Fig. 3

Reformatted 3-chamber view (a) and axial (b) CTA of the heart and proximal aorta showing the normal relation of the aortic root to the left atrium. No soft tissue should be present between the wall of the left coronary sinus and the left atrium (black arrow). In patients with aortic root infection, this space (black arrow) is increased with soft tissue. Abbreviations: AA, ascending aorta; LA, left atrium; LV, left ventricle; PA, pulmonary artery; An, annulus; S, sinus of Valsalva; STJ, sinotubular junction
