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 cardiac magnetic resonance imaging (MRI) is useful for detecting atrial thrombi in persons with atrial fibrillation.

Cardiac MRI

• Recent studies suggest that Late gadolinium enhancement (LGE) cardiac magnetic resonance imaging (MRI) is a powerful tool to detect atrial fibrosis.
• Moreover this diagnostic tool can be use to detect thrombosis within the atrium. Based on a analysis study done on 582 patients from seven publications cine-cardiac magnetic resonance imaging (MRI) has a pooled sensitivity and specificity of 91.00% and 93.00%, respectively.

Cardiac magnetic resonance imaging (MRI) may be used for assessing left atrial structure and function in patients with atrial fibrillation. The writing committee recognizes that evolving techniques utilizing late gadolinium enhancement (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 cardiac magnetic resonance imaging (MRI) provides a reliable effective method for detecting thrombi in the left atrial appendage in patients with atrial fibrillation. Cardiac magnetic resonance imaging (MRI) is recommended for identifying pulmonary vein anatomy prior to or after electrophysiology procedures without need for patient exposure to ionizing radiation.
