Abstract:
Embolic sources were investigated in 74 ischemic stroke patients with nonvalvular atrial fibrillation using transesophageal echocardiography. In patients without left atrial spontaneous echo contrast, 78% had some embolic sources other than left atrial thrombus or spontaneous echo contrast, suggesting that these embolic sources play an important role in patients with nonvalvular atrial fibrillation.
