In congenital heart disease (CHD), CT cardiac angiography (CTCA) has an important role in surgical planning and evaluating post-surgical complications, complementing echocardiography and cardiac magnetic resonance imaging (cMRI). Its strengths are in its high spatial resolution, rapid acquisition, and excellent 3D reconstruction capabilities for visualization of complex vascular and intracardiac relationships. However, unless radiologists tailor reconstructions and reports to address the surgeons’ needs, its full potential is underutilized. To do this, radiologists need to be aware of at least broad strokes of cardiac pathophysiology, as well as modern surgical approaches and potential post-surgical complications, for the most common CHDs. This will ensure that the utility of CTCA reports transcend volumetric and vascular measurements, and instead, anticipate technical challenges, identify hidden hazards, shape surgical strategy and pick up specific post-surgical complications. We propose structured CTCA reporting framework for CHD centred on the needs of the surgeon, by prioritising specific information surgeons find most useful across various CHD conditions. The objectives of this poster are a) to review, by consensus with paediatric cardiac surgeons, the key imaging features in CTCA based on different CHD lesions. b) To propose a reporting checklist for CTCA that emphasizes those key features. c) To demonstrate application of this surgeon centric framework via illustrative cases, focusing on the tetralogy of Fallot, transposition of great arteries, total or partial anomalous pulmonary venous return, and coarctation of the aorta.

Congenital extrahepatic portosystemic shunt (CEPS), also known as Abernethy malformation, is a rare congenital vascular abnormality in which portosplenomesenteric blood drains directly into the systemic venous system, thus bypassing the liver via an extrahepatic shunt. CEPS classification is based on the shunt anatomy and presence of an intrahepatic portal venous supply, which affects the form of definitive treatment available. Complications can arise due to the metabolic abnormalities and altered hemodynamics brought about by the shunt. Imaging plays a crucial role in the initial diagnosis and surgical planning, as well as the identification and monitoring of complications. The purpose of this educational exhibit is to review the CEPS embryological origins, classification system and complications through various case examples across different imaging modalities (ultrasound, CT, MRI and angiography).
