Four cases of cor triatriatum are reported. Cases 1 and 2 had IIA, case 3 had IA, and case 4 had IIIB 1 type of cor triatriatum according to Lucas-Schmidt classification. Cases 1 and 2 were diagnosed by echocardiography preoperatively. They were not performed cineangiocardiography because of pulmonary congestion. Case 3 had type IA so called classical type, which is hemodynamically identical to mitral stenosis and supravalvular stenosing ring. The clinical features are depend on the size of the communication between accessory chamber and true left atrium. As case 4, he had been diagnosed of simple atrial septal defect preoperatively, careful echocardiographic examination was essential for accurate diagnosis. In case 2 with hypoplastic left heart, secondary surgical repair is considered to be desirable followed by balloon dilatation of two atrial septal defects communicated to accessory chamber and to true left atrium. Thus, we expect development of hypoplastic left ventricle.
报告了4例三房心病例。根据卢卡斯 - 施密特分类，病例1和病例2为IIA型，病例3为IA型，病例4为IIIB 1型三房心。病例1和病例2术前通过超声心动图诊断。由于肺充血，未进行心血管造影。病例3为IA型，即所谓的经典型，其血流动力学与二尖瓣狭窄和瓣上狭窄环相同。临床特征取决于副房与真正左心房之间交通口的大小。如病例4，术前被诊断为单纯房间隔缺损，仔细的超声心动图检查对于准确诊断至关重要。对于病例2合并左心发育不全，在对与副房和真正左心房相通的两个房间隔缺损进行球囊扩张后，考虑进行二期手术修复。因此，我们预计左心室发育不全。
