Left Atrial Enlargement on Transthoracic Echocardiography Predicts Left Atrial Thrombus on Transesophageal Echocardiography in Ischemic Stroke Patients
Table 3
Transesophageal echocardiographic determination of cardiac characteristics of AIS patients (results stated with number of patients observed with noted characteristic on TEE; percentage noted subsequently is a comparison to the number of patients who have a certain characteristic on TTE).
