In this episode, we review aortic intramural hematoma (IMH), penetrating aortic ulcer (PAU), infectious aortitis and aortic atheroemboli. What condition is characterized by a crescentic aortic wall thickening and echolucency within the aortic wall with no intimal flap on transesophageal echocardiogram? What percent of IMH progresses to aortic dissection?What imaging findings distinguish IMH from dissection on non-contrast CT, contrast CT, and TEE? What are the criteria for complicated IMH, and when is emergent surgical repair recommended? How does the management of type A IMH differ from that of type B IMH? How are grades 1, 2, 3, 4, and 5 aortic plaques defined? What features on imaging of PAU designate PAU as high-risk? When should PAU be repaired? Which organisms are responsible for infectious aortitis? Tune in for answers to these questions.
