Abstract

Atrial septal pouch is a recently described anatomical entity. We describe webbed left atrial septal pouch (LSP), a new variant in the spectrum of fusion of septum primum and septum secundum. In the continuum of the natural history of atrial septal closure from patent foramen ovale (PFO) to complete fusion of the septum, we propose the septal anatomy in our patient to be secondary to partially developed adhesions or septa. Potential association of LSP with stroke due to in situ thrombosis and atrial fibrillation has been described. Recognition of septal anatomy is vital to avoid complications related to transseptal puncture.
