Abstract: A 78-year-old man with remote type-A dissection presented with acute-onset dyspnea. Twenty-two years prior, treatment for his aortic disease required replacement of ascending and arch aneurysms with a polyester graft (Dacron) using the graft inclusion technique. He presented currently in cardiogenic shock. Echocardiography demonstrated new severe hypokinesis of all apical segments. Left-heart catheterization revealed a 120 mm Hg intragraft gradient. Computed tomography arteriography was unrevealing, but intraaortic ultrasound demonstrated critical intragraft stenosis. A balloon expandable stent (Palmaz stent, Cordis, Milpitas, CA) was deployed in the stenotic region with gradient resolution. The patient later underwent aortic root replacement and ascending aneurysm repair (Bio-Bentall technique) and is doing well at 24 months.<br /> (Copyright © 2018 The Society of Thoracic Surgeons.
