Interventions in congenital heart diseases (CHD) are medical procedures aimed at correcting structural heart abnormalities present from birth. These conditions can range from simple defects, like a small hole in the heart, to more complex issues, such as malformed valves or arteries. The type of intervention depends on the severity and specific nature of the defect. In many cases, interventions are performed to improve blood flow, prevent complications, and enhance quality of life.

Non-surgical interventions include catheter-based procedures, such as balloon angioplasty, which is used to widen narrowed vessels, or stenting to support weakened arteries. In some cases, a device may be inserted through a catheter to close holes in the heart, such as in atrial septal defects. Surgical options are also common, ranging from repairs to more complex surgeries like valve replacements or the creation of new pathways for blood flow.
