Ten patients with calcifications of the left atrium are reported with review of the literature. Calcification of the left atrium is frequently associated with history of rheumatic fever, longstanding congestive heart failure, atrial fibrillation, mural thrombus and embolization. Early recognition of such lesions is essential for the management of the patients, particularly when surgical intervention is contemplated. A practical classification of left atrial calcification is proposed according to the dominant lesion in each group: (a) Calcification of the left atrial appendage alone (Mitral stenosis). (b) cacification of all 3 component lesions of the left atrium, i.e., the left atrial appendage, the free wall, and the mitral valve (Severe mitral stenosis). (c) Calcification of the left atrium in MacCallum's patch alone (Mitral insufficiency).
本文报告了10例左心房钙化患者，并对相关文献进行了回顾。左心房钙化常与风湿热病史、长期充血性心力衰竭、心房颤动、壁血栓形成和栓塞有关。早期识别此类病变对于患者的治疗至关重要，尤其是在考虑手术干预时。根据每组中的主要病变，提出了一种实用的左心房钙化分类方法：(a) 仅左心耳钙化（二尖瓣狭窄）。(b) 左心房的所有三个组成部分病变钙化，即左心耳、游离壁和二尖瓣（重度二尖瓣狭窄）。(c) 仅麦卡勒姆斑处的左心房钙化（二尖瓣关闭不全）。
