“…In these adult cases, communication between the IAC and adjacent atria is highly variable. Three cases 1 , 6 showed no communication with either atrium, five showed communication with both atria, 2 , 3 , 7 and five 5 , 8 , 9 , 10 , 11 were similar to the present one in having the IAC communicate only with the left atrium. Association with systemic thromboembolism was noted in five of these cases (38%).…”

“…The LASP is one of the potential sites for blood clots formation and can be a potential source of systemic thromboembolism. The other differential diagnosis of the LASP is double atrial septum with a persistent interatrial space [ 13 ]. The double atrial septum is an extremely rare congenital anomaly, which has a double-walled atrial septum that distinguishes the midline interatrial chamber between the two atria.…”

The incomplete fusion of the septum primum and septum secundum results in the formation of the left atrial septal pouch (LASP). The clinical significance of this entity is a matter of controversy; however, it may act as a nidus for thrombus formation. We report a case of a 57-year-old male who was brought to the hospital by his girlfriend due to his bizarre behavior and confusion for one day. The initial workup for his altered mental status did not yield a diagnosis. The patient was admitted for further workup, which included an MRI of the brain that showed numerous very small-sized foci of restricted diffusion involving bilateral cerebral and cerebellar hemispheres consistent with thromboembolic infarct. The patient did not receive a tissue plasminogen activator (TPA) as he was out of the window for TPA. Transthoracic echocardiogram (TTE) with bubble study did not show patent foramen ovale (PFO) or atrial septal defect (ASD). ECG and telemetry showed normal sinus rhythm and no atrial fibrillation. A transesophageal echocardiogram (TEE) was obtained to find the source of the thromboembolic stroke. TEE discovered a 22 x 8-mm cystic structure in the interatrial septum consistent with a LASP. We hypothesize that the LASP may be a risk factor for cryptogenic stroke. Further research is needed to determine the prevalence of atrial septal pouch (ASP) in the general population, its clinical significance, and guidelines for treatment implications.

“…A subcostal view is essential for this diagnosis. 10 The morphology of SP is well known, but more studies are essential to confirm the relationship between this structure and thromboembolic complications.…”
