Right atrial enlargement
Medical condition
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. Common causes include pulmonary hypertension, which can be the primary defect leading to RAE, or pulmonary hypertension secondary to tricuspid stenosis; pulmonary stenosis or Tetralogy of Fallot i.e. congenital diseases; chronic lung disease, such as cor pulmonale. Other recognised causes are: right ventricular failure, tricuspid regurgitation, and atrial septal defect. Right atrial enlargement (RAE) is clinically significant due to its prevalence in diagnosing supraventricular arrhythmias. Further, early diagnosis using risk factors like RAE may decrease mortality because patients with RAE are at 9x more risk of arrhythmias and other cardiac conditions compared to their healthy counterparts.
