Why the study?
Does MRI accurately detect thrombus in the left atrial appendage compared to TEE in patients with nonrheumatic continuous atrial fibrillation and previous cardioembolic stroke?
Does MRI accurately detect thrombus in the left atrial appendage compared to TEE in patients with nonrheumatic continuous atrial fibrillation and previous cardioembolic stroke?
MRI is a highly concordant, noninvasive alternative to TEE for detecting left atrial appendage thrombus in patients with atrial fibrillation.
