The left atrial septal pouch (LASP) is an anatomic variant of the interatrial septum and may be a nidus for thromboembolism. We present the case of a 49 year-old man without known vascular risk factors who experienced bi-hemispheric strokes over the course of 10 days, suggestive of multiple emboli. Transesophageal echocardiography revealed a prominent LASP. We suggest that presence of LASP was a likely cause of stroke in this patient and that further study of a possible association between LASP and ischemic stroke in younger individuals may be warranted.
左心房间隔袋（LASP）是房间隔的一种解剖变异，可能是血栓栓塞的病灶。我们报告一例49岁男性病例，该患者无已知血管危险因素，在10天内发生双侧半球性卒中，提示多发性栓子。经食管超声心动图显示一个明显的LASP。我们认为LASP的存在可能是该患者卒中的原因，并且可能有必要进一步研究LASP与年轻个体缺血性卒中之间的潜在关联。
