For a more accurate valvular morphology assessment and in the face of surgery, a transesophageal echocardiogram was requested (Figs. 1A and B) in which a unicuspid aortic valve with severe insufficiency and high gradients in probable relationship with overflow was observed. A dilated and spheroidal LV and aneurysmal dilatation of ascending aorta (46 mm x 45 mm, ASI > 25 mm/m2) were observed and confirmed in aortic computed tomography scan (Fig. 1C). In the control echo immediately after surgery, minimal aortic insufficiency was observed (Fig. 1D).
