Key result
A double atrial septum with a persistent interatrial space communicating with the left atrium was identified as the probable source of thrombus in a patient with a transient ischemic attack.
Highlights double atrial septum with persistent interatrial space as a potential source of thrombus in patients with transient ischaemic attack.
Hypothesis-generating in one TIA case; leaves open prevalence, causality, and need for prospective validation.
We present the echocardiographic images of a patient with transient ischaemic attack with double atrial septum and persistent interatrial space as probable source of thrombus. A patent foramen ovale could be excluded and a communication between left atrium and interatrial space could be demonstrated.

Seyfert et al. (2008) studied this question. A double atrial septum with a persistent interatrial space communicating with the left atrium was identified as the probable source of thrombus in a patient with a transient ischemic attack.
