July Answer: This is a beautiful example of a quadricuspid aortic valve with central aortic regurgitation as imaged by G. Burkhard Mackensen. This is a rare congenital abnormality with a reported prevalence of between 0.01%–0.04%. Quadricuspid aortic stenosis is rare, but as in this case, thickened leaflets with significant aortic regurgitation is common.

June Answer: The structure in question is a pseudoaneurysm of the mitral aortic intervalvular fibrosa, an area which is especially prone to complications following aortic valve endocarditis. In the current case, the patient had a previous tissue aortic valve replacement. It is likely that he subsequently developed endocarditis with pseudoaneurysm formation posterior to the aortic root. Color flow Doppler establishes to and fro movement form the LVOT to the pseudoaneurysm, and the absence of any communication with the left atrium. The asterix indicates the orifice of the pseudoaneurysm in the 3D image:
