  • 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. (edu.au)
  • 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. (edu.au)

  • Earlier in the gestation, closure of the foramen has been associated with severe hypoplasia of the left ventricle whereas later closure has been associated with right heart failure and rarely with the formation of an aneurysm of the atrial septum. (biomedcentral.com)
