Diagnostic Considerations

Approach considerations

Important considerations include the following:

  • It is important for clinicians to properly diagnose truncus arteriosus.

  • Consider various abnormalities that may be associated with truncus arteriosus, some of which may have an impact on management and outcome.

  • Also consider potential issues that are of particular concern in patients with truncus arteriosus, including pulmonary hypertensive crisis and volume overload in patients with persistent truncal valve regurgitation.

  • Obtain routine laboratory and imaging studies (to include a full complement of echocardiographic views) in the neonate with truncus arteriosus to aid in determining therapeutic strategy and assist diagnosis.

  • Consult with a cardiologist before beginning, changing, or discontinuing cardiac medications in these patients.
