Imaging for Risk Stratification in Atrial Fibrillation with Heart Failure.

Atrial fibrillation (AF) is the most common cardiac rhythm disorder and is associated with heart failure (HF). Cardiac imaging modalities play an important role in risk assessment and managing AF. This article reviews the use of cardiac imaging for risk assessment and to optimize treatment strategy in patients with AF and HF. First, the clinical role of echocardiography, computed tomography, and cardiac magnetic resonance for risk stratification is provided. Second, the value of imaging in catheter ablation is reviewed, including preoperative assessment, optimizing patient selection for ablation, use during the ablation procedure, and postoperative scar assessment.
