Aortic dissection after transcatheter aortic valve replacement

Figure 1. (A) Axial and, (B) Sagittal view of an unenhanced computed tomography (CT) of the chest showing a prominent aneurysmal dilation of the thoracic aorta with severe atherosclerotic vascular calcifications and internal displacement of mural calcifications toward the aortic lumen (arrows), suggestive of a Stanford type A aortic dissection; and demonstration of a prosthetic aortic valve in appropriate location (black arrowheads). AA, aortic arch; AS, ascending aorta; DS, descending aorta. Transthoracic echocardiogram, (C) parasternal short‐ axis view, and (D) parasternal long‐ axis view showing a severely dilated ascending aorta with a complex intimal flap (arrow) that divides the aorta into two, true and false, lumen; and (D) demonstrates the true lumen by color Doppler (asterisks) and a pericardial effusion. FL, false lumen; PE, pericardial effusion; TL, true lumen
