Overview

Cardiac magnetic resonance imaging may be used to assess the structure and the function of the atria in patients with atrial fibrillation. Further studies are needed to determine whether CMR is useful for detecting atrial thrombi in persons with atrial fibrillation.

“

CMR may be used for assessing left atrial structure and function in patients with atrial fibrillation. The writing committee recognizes that evolving techniques utilizing LGE may have high utility for identifying evidence of fibrotic tissue within the atrial wall or an adjoining structure. Standardization of protocols and further studies are needed to determine if CMR provides a reliable effective method for detecting thrombi in the left atrial appendage in patients with atrial fibrillation. CMR is recommended for identifying pulmonary vein anatomy prior to or after electrophysiology procedures without need for patient exposure to ionizing radiation.
