Left Atrial Appendage Filling Defects on 64-Slice Multidetector Computed Tomography in Patients Undergoing Pulmonary Vein Isolation

Abstract

A larger LA predisposes to LAA filling defects on MDCT scan. Pending prospective validation, absence of LAA filling defects on 64-slice MDCT may reliably exclude LAA thrombi in patients with nonvalvular atrial fibrillation obviating the need for TEE.
