Heart Disease

Atrial Septal Defect (ASD) in Children

The atrial septum is the wall between the two upper chambers of the heart (right and left atria). An atrial septal defect (ASD) is an abnormal hole in this wall. ASD is a heart problem that is present at birth (congenital). Read on for details about symptoms, diagnosis, and treatment.

Ventricular Septal Defect (VSD)

A ventricular septal defect (VSD) is a congenital heart defect. This means that your baby is born with it. A VSD is an opening or hole in the dividing wall (septum) between the 2 lower chambers of the heart (right and left ventricles). VSDs are the most common type of congenital heart defect.

Atrioventricular (AV) Canal Defect in Children

An atrioventricular (AV) canal defect is a congenital heart defect. This means that your child is born with it. These defects may range from partial to complete. These conditions cause oxygen-rich (red) blood and oxygen-poor (blue) blood to mix. This sends extra blood to the child's lungs.

Tricuspid Atresia

Tricuspid atresia (TA) is a heart defect present at birth (congenital). It occurs when the tricuspid valve doesn’t form right during fetal heart development. This happens during the first 8 weeks of pregnancy. Read on to learn details about this condition.

Pulmonary Atresia

Pulmonary atresia (PA) is a heart defect. It happens when the fetal heart doesn’t form as it should during the first 8 weeks of pregnancy.

Transposition of the Great Arteries (TGA) in Children

Transposition of the great arteries (TGA) is a type of congenital heart defect. This means that your baby is born with it. In this condition, the large blood vessels that carry blood from the heart to the lungs and body aren’t connected as they should be.

Tetralogy of Fallot (TOF)

Tetralogy of Fallot is 4 congenital heart defects. This means that your child is born with them. These 4 problems occur together (tetralogy refers to 4).

Coarctation of the Aorta (COA) in Children

Coarctation of the aorta is a heart defect that's present at birth (congenital). It means the aorta is narrower than it should be. Read on to learn details about the condition.

Aortic Stenosis in Children

Aortic stenosis means that your child has a heart valve that is too narrow or is blocked.  The aortic valve is 1 of 4 heart valves that keep blood flowing through the heart. The valves make sure blood flows in only one direction. The aortic valve keeps blood flowing from the left ventricle to the aorta.

Pulmonary Stenosis in Children

Pulmonary stenosis is a birth defect of the heart (congenital). It can happen when the pulmonary valve doesn’t develop as it should during the first 8 weeks of pregnancy. The pulmonary valve connects the right ventricle to the pulmonary artery.

Patent Ductus Arteriosus (PDA)

Patent ductus arteriosus (PDA) is a heart defect found in the days or weeks after birth. Read on to learn about symptoms, diagnosis, and treatment options.
