Efficacy of Optison Echo Contrast to Detect Thrombus in Left Atrial Appendage

Completed · Phase 4

Conditions studied: Atrial Fibrillation

In brief

The investigators intend to determine if using Optison echocardiography contrast increases sensitivity and specificity of detecting left atrial appendage thrombus in transesophageal echocardiography studies as opposed to standard 2D and 3D TEE imaging without the use of echo contrast.
