Right atrial enlargement (RAE) is a form of cardiomegaly, or heart enlargement. It can broadly be classified as either right atrial hypertrophy (RAH), overgrowth, or dilation, like an expanding balloon. Right atrial enlargement (RAE) is clinically significant due to its prevalence in diagnosing supraventricular arrhythmias.
