Echocardiography and cardiac magnetic resonance imaging are the methods of choice for preoperative and postoperative assessments of most congenital heart diseases. However, multidetector computed tomographic angiography of the chest is a complementary imaging technique especially in postoperative evaluations. To accurately interpret those computed tomography examinations, an appropriate study protocol, knowledge of the details of surgical procedures, and their complications are essential. In this pictorial review, we discuss our computed tomography technique with a number of illustrative cases with varied postoperative appearances and complications after some of the commonly performed surgical procedures. © 2014 Elsevier Inc.
