Transesophageal echocardiography (TEE) and cardiac computed tomography (CT) showed an outpouching structure at aortomitral intervalvular fibrosa (Figure 1A-D, Supplementary Video 1), compatible with pseudoaneurysm suggesting sequelae of previous infective endocarditis. As he did not suffer from fever or elevated inflammatory markers, surgical aortic valve replacement (SAVR) was performed. On surgery, when extracting the leaflets, subannular pouching was seen without evidence of active inflammation or infection (Figure 1E and F).
