Aortic rupture and transection are constituents of the acute aortic syndrome. Injury to the thoracic aorta during motor vehicle crashes is associated with blunt chest trauma and rapid deceleration mechanisms. Type A dissections and/or rupture of the aorta at the level of the aortic isthmus are the more common presentations of aortic injuries associated with motor vehicle crashes. We present the case of atypical echocardiographic findings of a nearly complete circumferential transection of the proximal ascending aorta injury after a motorcycle crash.
