Overview
Computed tomography can be helpful as a diagnostic tool in conditions where the echocardiographic findings are inconclusive.
CT Scan
Shown below is the plain CT of a patient with supravalvular aortic stenosis. The image shows an almost circular supravalvular aortic calcification of the aortic wall with extension of calcifications into the left main stem. The area of calcification is shown in yellow.[1]
Advantages
- CT scan provides additional anatomic details compared to echocardiography.
- It may allow quantitattion of chamber sizes and calcification of the aortic valve.
- The presence of calcification is a marker of hemodynamic severity, particularly in the younger patient.
- It is done faster compared to MRI, thus avoiding the need for anesthesia in small children.
Disadvantages
- CT scan is costly.
- Radiation can have long terms side-effect on growing children.
