Closure of atrial septal defect (ASD) is critically dependent on the shunt flow direction. However, shunt flow direction through ASD may change under variable clinical conditions. We present here a 53-year-old woman with a confirmed left-to-right shunt ASD prior to Amplatzer Septal Occluder placement. The development of atrial flutter during the procedure had been found to change the shunt from unidirectional to bidirectional and the procedure was then forced to a temporary halt. The cardiac arrhythmia and altered shunt direction simultaneously reverted to the old state after cardioversion. A successful placement of Amplatzer septal occluder was successfully performed afterward and she recovered uneventfully.
房间隔缺损（ASD）的封堵严重依赖于分流方向。然而，在不同临床情况下，通过ASD的分流方向可能会改变。我们在此介绍一名53岁女性，在植入Amplatzer房间隔封堵器之前已确诊为左向右分流的ASD。术中发现房扑的发生使分流从单向变为双向，手术被迫暂时中止。心脏复律后，心律失常和改变的分流方向同时恢复到原来的状态。随后成功植入了Amplatzer房间隔封堵器，她恢复顺利。
