Forty consecutive patients undergoing mitral valve replacement with a giant left atrium, form the basis of this report. Two groups could be identified: (a) isolated giant left atrium (11 cases); (b) combined left and right atrial enlargement (29 cases). Tricuspid regurgitation was only detected in the latter group. The early hospital mortality was 20% and was related to the pulmonary arterial systolic pressure. A giant left atrium increased the operative mortality from 7% to 20% among patients submitted to mitral valve replacement in our unit (p less than 0.05).
本报告基于连续40例接受二尖瓣置换术且伴有巨大左心房的患者。可分为两组：(a) 单纯巨大左心房（11例）；(b) 左、右心房联合增大（29例）。仅在后一组中检测到三尖瓣反流。早期医院死亡率为20%，与肺动脉收缩压有关。在我们单位接受二尖瓣置换术的患者中，巨大左心房使手术死亡率从7%增加到20%（p<0.05）。
