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.
房间隔袋是一种最近才被描述的解剖学实体。我们描述了蹼状左房隔袋（LSP），这是原发隔与继发隔融合谱系中的一种新变体。在从卵圆孔未闭（PFO）到房间隔完全融合的房间隔闭合自然病程连续体中，我们认为我们患者的隔部解剖结构是继发于部分发育的粘连或隔片。LSP与原位血栓形成和房颤导致的卒中之间的潜在关联已被描述。认识隔部解剖结构对于避免与经房间隔穿刺相关的并发症至关重要。
