Double Inter-atrial Septum: A Rare Cause of Cardioembolic Stroke

Published:October 08, 2012DOI:
      Double inter-atrial septum is an exceedingly rare congenital cardiac abnormality. We describe a case of transient ischaemic attack in a 53 year-old female found to have double inter-atrial septa on transthoracic and transoesophageal echocardiography. The midline inter-atrial chamber enclosed by the two septa was found to be continuous with the left atrium, with stasis in this accessory chamber predisposing to thrombus formation and cardio-embolic events. The case highlights the importance of transoesophageal echocardiography in the investigation of stroke, particularly in younger individuals.
