WebOct 21, 2024 · A ventricular septal defect (VSD) is a hole in the heart. It's a common heart problem present at birth (congenital heart defect). The hole occurs in the wall that separates the heart's lower chambers (ventricles). A VSD changes how blood flows through the heart and lungs. Oxygen-rich blood gets pumped back to the lungs instead of out to the body.
