Left atrial (LA) calcification is mostly observed in patients with rheumatic mitral valve (MV) diseases who underwent surgical treatment. We report a case of LA calcification in a 69-year-old woman presented with dyspnea and cyanosis. Admission electrocardiogram showed atrial fibrillation and biventricular hypertrophy. Her chest roentgenogram revealed cardiomegaly and a curvilinear whitish shadow in the area of LA. Transthoracic echocardiography revealed severe mitral stenosis and massive LA thrombosis. The patient underwent an emergent surgery, during which the whitish line on chest roentgenogram proved to be a calcified LA inner wall. During an on-pump surgery with cardioplegic arrest, she underwent open MV commissurotomy along with the excision of calcified LA wall and clots. The patient was discharged with no complications. Literature reviews showed that this entity is mainly observed in patients with rheumatic heart disease and presented with respiratory symptoms. The diagnostic modalities, management, and prognosis of previous cases were summarized.
左心房（LA）钙化多见于接受手术治疗的风湿性二尖瓣（MV）疾病患者。我们报告一例69岁女性患者，表现为呼吸困难和发绀，存在左心房钙化。入院心电图显示心房颤动和双心室肥厚。胸部X线片显示心脏扩大，左心房区域有一条曲线状白色阴影。经胸超声心动图显示严重二尖瓣狭窄和大量左心房血栓形成。患者接受了急诊手术，术中胸部X线片上的白线被证实为钙化的左心房内壁。在心脏停搏的体外循环手术中，她接受了开放式二尖瓣交界切开术，同时切除钙化的左心房壁和血栓。患者出院时无并发症。文献综述表明，该病症主要见于风湿性心脏病患者，并表现为呼吸道症状。总结了既往病例的诊断方法、治疗及预后情况。
