Optimizing Cardiac CTA Acquisition in Congenital Heart Disease
- 24 Downloads
Purpose of Review
The purpose of this review of performance of cardiac computed tomographic angiography (CCTA) in patients with congenital heart disease (CHD) is to describe a strategy for optimizing CCTA protocols for various forms of CHD at diagnosis and throughout the lifetime of a patient.
Recent expert consensus statements provide key recommendations for patient selection and technical performance of CCTA with tips to optimize contrast injection, scan acquisition, and understanding anatomy and postoperative changes in patients with CHD. Spectral CT will become invaluable in acquiring image data which has potential for enabling improved image quality and perhaps physiologic information.
CCTA is an important non-invasive imaging modality for making initial diagnosis and providing follow-up imaging in patients of all ages with CHD. Optimization of imaging protocols requires combined expertise in all forms of CHD, surgical palliation procedures, and knowledge of surgical options for CHD surgery.
