Single-vessel versus multivessel territory acute ischemic stroke: value of transesophageal echocardiography in the differentiation of embolic stroke.
We sought to assess the presence of potential aortic or cardiac sources of embolism in patients presenting with acute ischemic stroke in one or more vascular territories. ⋯ In patients with acute ischemic stroke, the incidence of a potential cardiac or aortic source of embolism is high, regardless of the vascular distribution of the stroke. TEE may be a useful tool to assess the source of stroke in single-vessel, multivessel, and lacunar territory stroke distribution. We aimed to assess the presence of potential aortic or cardiac sources of embolism in patients presenting with acute ischemic stroke in one or more vascular territories. A total of 210 patients with acute ischemic stroke were divided into 3 groups (lacunar stroke, nonlacunar stroke/single-vessel involvement, nonlacunar stroke/multivessel involvement) and the frequency of potential embolic sources on transesophageal echocardiography was compared. Patients with multivessel strokes had fewer potential embolic sources on transesophageal echocardiography than patients with single-vessel or lacunar strokes, but the frequency of a potential cardiac or aortic source of embolism was high, regardless of the vascular distribution of stroke.

Case ReportsDouble atrial septum with persistent interatrial space: echocardiographic features of a rare atrial septal malformation.
We describe the echocardiographic features of 4 new cases of a rare atrial septal malformation consisting a double atrial septum with a midline chamber between the left and right atrium. Half of the cases had major left-sided obstructive lesions. Transthoracic, transesophageal, intracardiac, and fetal echocardiographic features of this anomaly are demonstrated. Previous descriptions, embryologic speculations, and clinical considerations are discussed.
