BackgroundUlcerative aortic plaques (UAPs) are considered a major source of brain embolism. However, whether UAPs contribute to a specific stroke mechanism remains unknown.MethodsThree consecutive patients with recurrent embolic stroke underwent repeated transesophageal echocardiography (TEE) examinations after their initial and recurrent strokes.ResultsAll 3 patients had UAPs. Between TEEs, different morphologies of UAPs were found in cases 1 and 2, and case 3 maintained advanced UAPs with no significant morphological alteration. Case 3 underwent repeated contrast-enhanced computed tomographic examinations after each stroke event, which showed newly developed, uneven, ulcerative plaques in the aortic arch after recurrent stroke.ConclusionsRepeated TEE showed dynamic changes of UAPs in recurrent stroke patients and supported the diagnosis of aortogenic brain embolism.
