A patient in his 30s presented to the emergency department with transient monocular blindness but no cardiovascular symptoms. Cerebral magnetic resonance imaging was normal, and a transient ischemic attack (TIA) was diagnosed. Transthoracic echocardiography revealed a gigantic, dilated structure (Figure, A) corresponding to the ascending aorta, with severe stenotic type 0 bicuspid aortic valve. Computed tomography confirmed a massive, 122-mm ascending aortic dilation (3-dimensional reconstruction in Figure, B) with signs of prerupture, confined between the sternum and the spinal cord, compressing the left atrium. An urgent bioprosthetic Bentall surgery was performed.
