Surgical intervention for infants diagnosed with congenital heart disease addresses a variety of defects, including:

Some conditions may be treated using catheters - thin, flexible, narrow tubes threaded through blood vessels to the heart - rather than traditional, invasive cardiothoracic surgery. Cardiac catheterization can be used to make repairs, like closing holes in the heart muscle or removing obstructions from the blood vessels, or to place stents in narrowed or blocked blood vessels to keep them open.

Pediatric cardiac electrophysiology uses radiofrequency catheter ablation to treat cardiac arrhythmias, disrupting areas of the heart that are the source of the electrical irregularities.
