The Chiari network, a net-like structure within the right atrium, has been described as an embryonic remnant of no clinical significance. Its role in facilitating paradoxical arterial embolic events and as a potential site for thrombus formation has been reported in the literature. This case illustrates the protective filter-effect of the Chiari network in a 92-year-old women who presented with the clinical signs and symptoms of acute cor pulmonale. Transthoracic echocardiography revealed a large, S-shaped, and extremely mobile right atrial thrombus within the Chiari network. Here, the authors describe how the Chiari network may have prevented the occurrence of a fatal pulmonary embolism acting as a protective factor.
奇亚里网是右心房内的一种网状结构，曾被描述为无临床意义的胚胎残余物。其在促进反常动脉栓塞事件及作为血栓形成潜在部位方面的作用已有文献报道。本病例说明了奇亚里网在一名出现急性肺心病临床体征和症状的92岁女性中的保护滤过作用。经胸超声心动图显示奇亚里网内有一个大的、S形且活动度极大的右心房血栓。在此，作者描述了奇亚里网如何可能作为一种保护因素预防了致命性肺栓塞的发生。
