Down syndrome and other genetic conditions.Risk factors for ventricular septal defect include: A large VSD can also increase the amount of blood flow in the lung arteries, causing congestion. The heart then must work harder to pump blood. If the ventricular septal defect is large, the blood pressure in the lung arteries may increase. Oxygen-rich blood and oxygen-poor blood now mix together. The hole lets oxygen-rich blood go back into the lungs, instead of going out to the body. The left side of the heart pumps the oxygen-rich blood to the rest of the body.Ī ventricular septal defect changes the direction of blood flow in the heart and lungs.The lungs pump the oxygen-rich blood to the heart's left side.The right side of the heart moves blood to the lungs.The typical heart is made of four chambers - two upper chambers (atria) and two lower chambers (ventricles). The heart valves, which keep blood flowing in the right direction, are gates at the chamber openings. The lower chambers, the more muscular right and left ventricles, pump blood out of the heart. The upper chambers, the right and left atria, receive incoming blood. Becomes breathless when eating or cryingĬall your provider if these symptoms develop:Ī typical heart has two upper and two lower chambers.Shortness of breath, especially when exercisingĬall your health care provider if your baby:.Symptoms of a ventricular septal defect in adults may include: Whooshing sound when listening to the heart with a stethoscope (heart murmur).Slow or no physical growth (failure to thrive).
In general, VSD symptoms in a baby may include: Symptoms of a ventricular septal defect (VSD) depend on the size of the hole and if there are any other heart problems. Symptoms of serious heart problems present at birth (congenital heart defects) often appear during the first few days, weeks or months of a child's life.
