Patent Ductus Arteriosus (PDA)

What you will learn

To assess a patent ductus arteriosus, you will need to know in which views you can see the defect, how to measure its size, and determine its hemodynamic effects. This is precisely what we will cover in this chapter. In addition, you will find out how patients with a PDA might present, which coexisting lesions you should look for, how to measure pulmonary pressure with the help of ductal flow and how such patients are treated.

Topics: 

• Anatomy of a PDA
• How to image a PDA
• Hemodynamics and size of the PDA
• Assessment of pulmonary pressure in PDA
• Volume overload in PDA
• Other imaging modalities - examples
• Management of PDA
