Abstract：
Mitral annular calcification (MAC) is relatively common in clinical practice. Females are more often affected than males. Patients with end-stage renal disease have MAC relatively more commonly than the general population. Patients with MAC often develop conduction system disturbances, including advanced atrioventricular blocks. They are also more likely to develop various arrhythmias, including atrial fibrillation. Caseous mitral annulus calcification is a variant of MAC that often looks like a cardiac tumor on an echocardiogram and needs to be differentiated.
摘要：
二尖瓣环钙化（MAC）在临床实践中相对常见。女性比男性更常受到影响。终末期肾病患者的MAC相对比普通人群更常见。MAC患者通常会出现传导系统紊乱，包括晚期房室传导阻滞.他们也更有可能发生各种心律失常，包括心房颤动.二尖瓣环钙化是MAC的一种变体，通常在超声心动图上看起来像心脏肿瘤，需要区分。
