Intracardiac echocardiography in congenital heart disease.

The use of intracardiac echocardiography (ICE) in congenital heart disease has become well established over the past 7 years since its introduction into clinical imaging. The greatest experience has been to guide percutaneous device closures of secundum atrial septal defects and patent foramen ovale, with excellent safety and clinical results. However, ICE has also been used for the evaluation and management of many other congenital heart defects given its unique blood/transducer interface and close proximity to relevant cardiac anatomy.
