Maximum intensity projection (MIP) documents a severely calcified aortic arch (A). multi planar reformation (MPR) images show an arteria lusoria (AL) in axial (B) and large calcifications of aortic arch in sagittal (C) and coronal (D) views. After transcatheter aortic valve implantation (E), MIP shows the presence of previously undetected calcifications at the thoraco-abdominal district (arrow), with a bulk mass entrapped in the descending aorta (computed tomography axial scan, F), later confirmed at computed tomography angiography performed at 6-month follow-up (coronal view, G).

Cardio, Saluggia, Italy), bioprosthesis dysfunction was documented. Computed tomography angiography (CTA) showed diffuse aortic calcifications and the presence of an aberrant right subclavian artery or arteria lusoria (AL) (Fig. 1A-D). Due to blood loss, CTA was required; aside a retroperitoneal hematoma, a large calcified plaque, previously undetected at the thoraco-abdominal passage was unexpectedly detected (Fig. 1E, F), causing a 50% caliber reduction.
