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.
