Detailed explanation-1: -The hole lets oxygen-rich blood go back into the lungs, instead of going out to the body. Oxygen-rich blood and oxygen-poor blood now mix together. If the ventricular septal defect is large, the blood pressure in the lung arteries may increase. The heart then must work harder to pump blood.
Detailed explanation-2: -In an atrial septal defect, there’s an opening in the wall (septum) between the atria. As a result, some oxygenated blood from the left atrium flows through the hole in the septum into the right atrium, where it mixes with oxygen-poor blood and increases the total amount of blood that flows toward the lungs.
Detailed explanation-3: -The septum helps keep oxygen-rich blood from the lungs from mixing with oxygen-poor blood from the body. It also prevents blood from flowing back into the heart chambers after pumping it out.
Detailed explanation-4: -Common risks can include: Allergic reaction to the dye used during the procedure. Irregular heartbeat, called arrhythmia. Bruising.
