Overview
Overview
A cardiac CT scan plays an important tool in the assessment of cyanotic congenital heart disease and determines the volume and size of cardiac chambers and determines the relation between the cardiac chambers and great arteries and veins.
CT scan
CT scan
- Cardiac computed tomography scan may be helpful in the diagnosis of cyanotic congenital heart disease. Findings on a cardiac CT scan for assessment of the anatomy of congenital heart disease may include:[1]
- Evaluation the position of aorta, pulmonary vein, pulmonary arteries
- Evaluation of the size and volume of cardiac chambers
- Evaluation of ventriculoarterial connection
- Evaluation the connection between upper lob bronchi and pulmonary arteries
- Evaluation of coronary arteries, valves, superior vena cava, inferior vena cava, hepatic veins
- Evaluation of visceral situs
- Findings on Chest CT scan for the diagnosis of pulmonary causes of cyanosis may include:
- Pneumonia (to view CT Scan features, click here)
- Pulmonary edema (to view CT Scan features, click here)
- Pulmonary embolism (to view CT Scan features, click here)
- Pulmonary hypertension (to view CT Scan features, click here)

Recommendation for Cardiac Computed Tomography in congenital heart disease according to 2018AHA/ACC Guideline
| Class of Recommendation | Level of Evidence | Recommendation |
|---|---|---|
| ॥a | C | CCT is useful in congenital heart disease when imaging can not be obtained by other modalities and the risk of exposure to ionizing radiation is lower than the benefit |

Congenital heart disease (CHD) is the most common type of birth defect, accounting for about 1% of all cases [4]. Although mild cases of CHD are not detected until after discharge, most of the critical CHD cases are identified soon after birth requiring surgery or catheter-based intervention in the first year of life. CHD is broadly classified into three major groups, namely, cyanotic CHD, ductal-dependent CHD and critical CHD. Cyanotic CHD involves defects that lead to mixing of deoxygenated blood into the systemic circulation. Ductal-dependent CHD relies on the patency of the ductus arteriosus for supply of blood to the pulmonary or systemic outflow which allows adequate mixing between the parallel circulations. Lesions requiring surgery or catheter-based intervention in the first year of life are referred to as critical CHD which includes ductal-dependent and cyanotic lesions, as well as forms of CHD that, although not requiring surgery in the neonatal period, do necessitate intervention in the first year of life, such as a big ventricular septal defect or an atrioventricular canal defect (or atrioventricular septal defect).
