Patient had been reevaluated 4 weeks later, finding worsened aortic regurgitation (3 + /4+) with regurgitant flow directed to the anterior MV leaflet and confirming the vegetation-like formation on A2 (suspecting now a pseudoaneurysm) with worsened MV regurgitation (3 + /4+) (Figures 1 and 2).

A2, with no signs of rupture (Figure 3); apart from that, anterior and posterior MV leaflets were normal. Aortic and mitral valves have been replaced with biological prosthesis (Carpentier-Edwards PERIMOUNT Magna Ease 25 mm and Medtronic Hancock
