We undertook a cost-effectiveness analysis to evaluate nine diagnostic strategies for identifying cardiovascular sources of emboli after stroke, including various combinations of transthoracic echocardiography, transesophageal echocardiography, and history of cardiac disease. The most cost-effective strategy was transesophageal echocardiography for all patients, with subsequent anticoagulation treatment for patients with left atrial thrombus. The results were moderately sensitive to the effectiveness and safety of anticoagulation. No strategy using transthoracic echocardiography was as cost-effective as transesophageal echocardiography alone.
