Mitral annular calcification (MAC) has been considered a risk factor for thrombo-embolic disease. Superimposed thrombus formation on MAC has not been well described as a possible underlying mechanism for this association. We report three patients with mobile left ventricular (LV) thrombus arising from the LV aspect of severe calcified mitral annulus in the setting of normal LV function, mitral valve function, and sinus rhythm.
二尖瓣环钙化（MAC）一直被认为是血栓栓塞性疾病的一个危险因素。MAC上叠加血栓形成作为这种关联的一种潜在机制尚未得到充分描述。我们报告了3例左心室（LV）功能正常、二尖瓣功能正常且为窦性心律情况下，重度钙化二尖瓣环左心室侧出现活动左心室血栓的患者。
