Cardiac Imaging to Assess Left Ventricular Systolic Function in Atrial Fibrillation

•There is a paucity of data to support the validity of systolic measurements in atrial fibrillation (AF) particularly for cardiac magnetic resonance, nuclear imaging and cardiac computed tomography.•The use of an index-beat has been shown to be reproducible and could have advantages over averaging beats in AF.•Global longitudinal strain is superior to left ventricular ejection fraction in predicting cardiovascular events.•Future studies are needed to determine the optimal method for assessing systolic function in patients with AF, including comparative multimodality imaging studies to ascertain if these parameters can be used interchangeably.
