Mitral annulus calcification has been associated with embolic events, but the precise pathophysiology has not been elucidated. The authors describe four patients who experienced embolic events whose transesophageal echocardiograms showed a mitral annulus calcification, with a mobile component that exhibited the same echogenicity as the calcification. Three patients had no other conditions known to be associated with embolism. On follow-up transesophageal echocardiography, the mobile component of the mitral annulus calcification had disappeared in three patients. These findings support the hypothesis that mitral annulus calcification not only is associated with but also is possibly a direct cause of embolic events in some patients.
二尖瓣环钙化与栓塞事件有关，但确切的病理生理学尚未阐明。作者描述了4例发生栓塞事件的患者，其经食管超声心动图显示二尖瓣环钙化，并有一个与钙化回声相同的活动成分。3例患者无其他已知与栓塞相关的疾病。在随访经食管超声心动图检查中，3例患者二尖瓣环钙化的活动成分消失。这些发现支持了这样一种假说，即二尖瓣环钙化不仅与某些患者的栓塞事件有关，而且可能是其直接原因。
