Aneurysms of the atrial septum (ASA) frequently diagnosed since the introduction of transoesophageal echocardiography are implicated in the aetiology of cerebral and systemic embolic events. This update was undertaken to resume recent data on this pathology and its relationship with embolic events. The diagnostic criteria are described together with the morphological features (size, movements, thickness) and associated abnormalities (interatrial shunts, valvular prolapse). The authors summarise the data concerning possible complications of ASA, especially the different mechanisms invoked to explain embolism (paradoxical embolism. thrombosis in situ, supraventricular arrhythmias). Therapeutic options are discussed with respect to the clinical contexts (therapeutic abstention, platelet antiaggregant drugs, oral anticoagulants, interventional cardiology or surgery.
自经食管超声心动图引入以来，频繁诊断出的房间隔动脉瘤（ASA）与脑和全身栓塞事件的病因有关。此次更新旨在总结有关这种病理及其与栓塞事件关系的最新数据。文中描述了诊断标准以及形态学特征（大小、活动度、厚度）和相关异常情况（房间隔分流、瓣膜脱垂）。作者总结了有关ASA可能并发症的数据，尤其是用于解释栓塞的不同机制（反常栓塞、原位血栓形成、室上性心律失常）。针对不同临床情况讨论了治疗选择（治疗性弃权、血小板抗聚集药物、口服抗凝剂、介入心脏病学或手术）。
