目的：探讨经食管超声心动图对先天性心脏病房间隔缺损（房缺）定量诊断的准确性。
Objective:To investigate the quantitative diagnostic accuracy of congenital atrial septal defect(ASD) by trans-esophageal echocardiography(TEE).
结论：对于周缘较硬的房缺，经食管超声心动图可直接指导封堵器大小的选择和封堵。
Conclusions: Echocardiography can be used for guidance of Amplatzer occlusion device of ASD with solid edge without the measurement of balloon expanding size of ASD.
结论年龄不是房缺手术的禁忌证，积极的围术期处理、合并症的同期手术处理是手术预后的关键。
Conclusion Age is not the contraindication for SASD operation. Positive peri-operation disposal and simultaneous operation disposal for complication are the key factors after operation.
结论：高龄本身并非老年房间隔缺损手术禁忌，老年患者通过封堵器或手术闭合房缺仍可以重构右心房、右心室，降低肺动脉压，显著改善心功能。
Closure of the ASD can still remodel the right atrium and ventricular, decrease the pulmonary artery pressure, and improve the cardiac function in the elderly patients.
