Heart Defects

  • Atrial Septal Defect (ASD)

    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).

  • Ventricular Septal Defect (VSD)

    A ventricular septal defect is an opening in the dividing wall between the two lower chambers of the heart known as the right and left ventricles.

  • Atrioventricular Canal (AV Canal or AVC)

    AV canal is a complex heart problem that involves several abnormalities of structures inside the heart.

  • 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. The tricuspid valve is located between the right upper chamber (atrium) and the right lower chamber (ventricle) of the heart. The defect keeps blood from flowing normally from the right atrium to the right ventricle.

  • Pulmonary Atresia

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

  • Transposition of the Great Arteries (TGA)

    Because of abnormal development of the fetal heart, the large vessels that take blood away from the heart to the lungs, or to the body, are improperly connected.

  • Tetralogy of Fallot

    Tetralogy of Fallot is a complex condition of several congenital heart defects.

  • Coarctation of the Aorta

    Coarctation of the aorta is a heart defect that is present at birth (congenital). It means the aorta is narrower than it should be.

  • 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. The ductus arteriosus is a normal part of fetal blood circulation. All babies are born with this opening between the aorta and the pulmonary artery. But it usually closes on its own shortly after birth. If it stays open, it is called patent ductus arteriosus.
