Abstract

OBJECTIVE

The essay describes the protocol for and interpretation of MDCT scans in the evaluation of patients after insertion of an Amplatzer septal occluder.

CONCLUSION

In anatomic regions that cannot be confidently evaluated with transthoracic echocardiography, MDCT is useful for evaluating Amplatzer septal occluders for protrusion, migration, and residual shunt. Radiologists should be familiar with the imaging protocol and interpretation.

摘要

目的

本文描述了在评估植入Amplatzer房间隔封堵器的患者时，多层螺旋CT（MDCT）扫描的方案及解读。

结论

在经胸超声心动图无法可靠评估的解剖区域，MDCT对于评估Amplatzer房间隔封堵器的突出、移位及残余分流情况很有用。放射科医生应熟悉成像方案及解读。
