Overview

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

CT in Ebstein's Anomaly

Findings

Inferior displacement of tricuspid valve leaflets with enlargement of the right atrium and enlargement and dysfunction of the right ventricle.

Advantages

• Provides additional anatomic details compared to echocardiography
• 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
