Is the left atrium the only embolic source in ischemic stroke patients with nonvalvular atrial fibrillation?
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.
