Massive calcification of the atrial walls ("porcelain atrium") is a rare condition that usually has been reported as an incidental radiologic findings.
Between January 1988 and June 1993, 971 patients underwent valvular operation at our institution; 21 patients showed extensive calcification of the left atrium. In 8 patients the calcification was massive, involving almost all the atrial surface. The diagnoses were established by radiology and were confirmed at operation. The mean age of these patients (4 men, 4 women) was 55 +/- 9.6 years. All had rheumatic valve disease, were on atrial fibrillation, and had undergone at least one operation previously. Pulmonary artery pressure was severely increased, even up to systemic levels, in all patients except 1. Total endoatriectomy of the left atrium and mitral valve replacement were performed. No patient was lost during the follow-up.
Hospital mortality rate was 12.5% (1 patient) and 2 patients died in the late postoperative period. None of these deaths are attributable to the surgical procedure.
In toto endoatriectomy of a massively calcified atrium is an easy to perform technique that helps to replace the mitral valve and close the atrial wall.
心房壁大量钙化（“瓷性心房”）是一种罕见情况，通常作为偶然的影像学发现被报道。
1988年1月至1993年6月期间，971例患者在我们机构接受了瓣膜手术；21例患者出现左心房广泛钙化。其中8例钙化严重，几乎累及整个心房表面。诊断通过影像学确立，并在手术中得到证实。这些患者（4名男性，4名女性）的平均年龄为55±9.6岁。所有患者均患有风湿性瓣膜病，处于心房颤动状态，且此前至少接受过一次手术。除1例患者外，所有患者的肺动脉压力均严重升高，甚至达到体循环水平。对左心房进行了全内膜切除术并置换了二尖瓣。随访期间无患者死亡。
医院死亡率为12.5%（1例患者），2例患者在术后晚期死亡。这些死亡均与手术操作无关。
对大量钙化的心房进行全内膜切除术是一种易于实施的技术，有助于置换二尖瓣并封闭心房壁。
