此前曾报道过超声心动图检测人工瓣膜相关股线，但其临床相关性尚不清楚。关于这些链的原因、组成和自然史的数据有限。本报告介绍了经食管超声心动图显示的机械人工瓣膜断裂的大体和组织病理学结果。患者既往未出现神经系统症状。链形成在各种临床环境中的潜在原因也进行了讨论。
Echocardiographic detection of prosthetic valve-associated strands has previously been reported, but their clinical relevance is unclear. Limited data are available regarding the cause, composition, and natural history of these strands. This report presents the gross and histopathologic findings of an explanted mechanical prosthetic valve shown by transesophageal echocardiography to have several strands. The patient had not experienced prior neurologic symptoms. Potential causes of strand formation in various clinical settings are also discussed.
