Overview

Computed tomography can be helpful as a diagnostic tool in conditions where the echocardiographic findings are inconclusive.

Advantages:

• Provides additional anatomic details compared to echocardiography.
• 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.

Disadvantage:

• Costly.
• Radiation can have long terms side-effect on growing children.
