Cor triatriatum is a rare congenital cardiac defect in which the atrium is divided into 2 chambers by a membrane causing obstruction to the blood flow in either the left atrium (cor triatriatum sinister) or the right atrium (cor triatriatum dexter) eventually leading to cardiac failure. We sought to review our surgical experience with cor triatriatum sinister.
Twenty-five patients underwent surgical correction of cor triatriatum between May 1960 and September 2012. There were 11 males and 14 females with a mean age of 27.4 years (age range, 1 day to 73 years).
All patients underwent excision of cor triatriatum membrane using cardiopulmonary bypass. Twenty patients (80%) required concomitant cardiac surgical procedures. There was no early mortality. None of the patients had any residual atrial obstruction. Two infants who had concomitant repair of complex congenital anomalies died at 2 and 5 months postoperatively after discharge from hospital. Kaplan-Meier survival at 10 years was 83%. All patients were in New York Heart Association class I or II at a mean follow-up of 12.8 years (maximum 44 years).
Surgical repair of cor triatriatum provides satisfactory early and long-term survival with low risk for additional intervention. Cor triatriatum with complex congenital anomalies may be associated with adverse outcome.
三房心是一种罕见的先天性心脏缺陷，由于隔膜的存在，心房被分隔成两个腔室，导致左心房（三房心左房）或右心房（三房心右房）的血液流动受阻，最终导致心力衰竭。我们旨在回顾我们在三房心手术治疗方面的经验。
1960 年 5 月至 2012 年 9 月，共有 25 例三房心患者接受了手术矫正。其中男性 11 例，女性 14 例，平均年龄 27.4 岁（年龄范围 1 天至 73 岁）。
所有患者均在体外循环下行三房心隔膜切除术。20 例（80%）患者需要同期心脏手术。无早期死亡病例。所有患者均无残余房内梗阻。2 例婴儿同时行复杂先天性畸形修复，术后 2 个月和 5 个月出院后死亡。10 年Kaplan-Meier 生存率为 83%。所有患者在平均 12.8 年（最长 44 年）的随访中均处于纽约心脏协会心功能Ⅰ级或Ⅱ级。
三房心的手术治疗可获得满意的早期和长期生存率，再次干预的风险较低。三房心合并复杂先天性畸形可能与不良结局相关。
