Ventricular Septal Defect

Ventricular septal defect (VSD), the most common heart problem that develops before birth (congenital), is an opening in the wall that separates the lower chambers of the heart. Most ventricular septal defects are small and do not cause a problem. The opening of a ventricular septal defect can be as small as a pinhole…

Cyanotic Heart Defects

Cyanotic heart defects are abnormal openings between the heart chambers that allow oxygen-poor blood from the right side of the heart to mix with oxygen-rich blood from the left side of the heart. When a large amount of oxygen-poor blood mixes with oxygen-rich blood, it causes a bluish tint (cyanosis) in the skin, lips…

Patent Foramen Ovale

The foramen ovale is an opening in the part of the heart that separates the upper right and left chambers (atria). In a fetus, this opening has a flap of tissue that acts like a one-way door—it allows blood to flow to the left side of the heart without going to the lungs, and it is kept open by the pressure of the blood…

Coarctation of the Aorta

Coarctation of the aorta is a common heart defect present at birth. With this defect, a portion of the large blood vessel that carries blood from the heart to the rest of the body (aorta) is abnormally narrowed or pinched. Coarctation of the aorta makes it harder for the heart to pump blood to the body. Over time, this…

Patent Ductus Arteriosus

The ductus arteriosus is a blood vessel in a fetus that connects the pulmonary artery, which carries blood to the lungs, and the aorta, which carries blood to the body, so that blood flow bypasses the lungs. Normally, this blood vessel closes at birth as the baby starts breathing. But if the vessel does not close, it is…
