房间隔瘤是一种少见的心脏结构畸形,其临床价值并不十分确切。房间隔常常并发房内分流,特别是在合并卵圆孔未闭时更容易发生。房间隔瘤病人有较高的脑卒中发生率。大量的研究结果表明,反常性栓塞是房间隔瘤病人发生脑卒中的主要机制。现就房间隔瘤与反常性栓塞相关性研究的新进展作一综述。 Atrial septal tumor is a rare cardiac structural deformity, its clinical value is not very clear. Atrial septum often concurrent shunt, especially in the merger foramen ovale more likely to occur. Atrial septal disease patients have a higher incidence of stroke. A large number of studies have shown that abnormal embolism is the main mechanism of stroke in patients with atrial septal lesions. A review of recent advances in the study of the relationship between atrial septal aneurysms and abnormal emboli was presented.
