Common atrium (CA) is a rare congenital heart defect. We reviewed our experience of surgical treatment of CA and summarize the clinical features of CA and the key techniques for surgical correction.
Between August 1984 and August 2010, 37 consecutive cases of CA underwent corrective surgery. There were no clinical findings of Down, asplenia-polysplenia or Ellis-van Creveld syndromes in all cases. Mitral valvuloplasty was performed in 34 cases, and tricuspid valvuloplasty in 20 cases. Complete closure of a mitral cleft was required in 32 cases. All new atrial septa were reconstructed using patches. Follow-up period ranged from 1 to 20 years.
There were no hospital deaths or conduction system block. After surgery, mild mitral insufficiency was observed in only one case. Two cases had moderate-severe mitral insufficiency at postoperative years 1 and 3, respectively, that required mitral valve replacements. One patient died of low cardiac output syndrome after reoperation.
Long-term survival after surgical correction of CA is good. Routine closure of a cleft in the mitral valve is very important for successful surgery.
共同心房（CA）是一种罕见的先天性心脏缺陷。我们回顾了我们对CA进行手术治疗的经验，并总结了CA的临床特征和手术矫正的关键技术。
1984年8月至2010年8月，连续37例CA患者接受了矫正手术。所有病例均无唐氏综合征、无脾-多脾综合征或埃利斯-范克里夫德综合征的临床表现。34例行二尖瓣成形术，20例行三尖瓣成形术。32例需要完全闭合二尖瓣裂。所有新的房间隔均采用补片重建。随访时间为1至20年。
无住院死亡或传导系统阻滞。术后仅1例出现轻度二尖瓣关闭不全。分别在术后第1年和第3年有2例出现中度至重度二尖瓣关闭不全，需要进行二尖瓣置换术。1例患者再次手术后死于低心排血量综合征。
CA手术矫正后的长期生存率良好。二尖瓣裂的常规闭合对手术成功非常重要。
