Axial (A) and coronal maximum-intensity projection MIP (B) images from a CTA of the chest demonstrate a blush of contrast (arrows) from the left ventricular outflow tract (LVOT) into the unopacified right atrium. The jet of contrast (arrow) from the LVOT extends to the right atrial free wall (arrowhead) as depicted in B.

CTA of the chest was performed using a 64-slice CT scanner (Philips Brilliance-64) (Fig. 1).
Transthoracic echocardiographic examination with apical four-chamber view shows a jet (arrows) originating from aortic root to the right atrium (RA). The RA does not appear to be enlarged.

There was a fairly prominent jet seen from that location moving into the right atrium, although the actual opening itself appeared to be small and well-defined. The right atrium itself did not appear to be enlarged (Figs. 2A, 2B).
