Congenital Heart Defects

A congenital heart defect is a problem with the structure of the heart. It is present at birth. Congenital heart defects are the most common type of birth defect. The defects can involve the walls of the heart, the valves of the heart, and the arteries and veins near the heart. They can disrupt the normal flow of blood through the heart. The blood flow can slow down, go in the wrong direction or to the wrong place, or be blocked completely.

Doctors use a physical exam and special heart tests to diagnose congenital heart defects. They often find severe defects during pregnancy or soon after birth. Signs and symptoms of severe defects in newborns include

  • Rapid breathing
  • Cyanosis - a bluish tint to the skin, lips, and fingernails
  • Fatigue
  • Poor blood circulation

Many congenital heart defects cause few or no signs and symptoms. They are often not diagnosed until children are older.

Many children with congenital heart defects don't need treatment, but others do. Treatment can include medicines, catheter procedures, surgery, and heart transplants. The treatment depends on the type of the defect, how severe it is, and a child's age, size, and general health.

Heart Valve Diseases

Also called: Valvular heart disease

Your heart has four valves. Normally, these valves open to let blood flow through or out of your heart, and then shut to keep it from flowing backward. But sometimes they don't work properly. If they don't, you could have

  • Regurgitation - when blood leaks back through the valve in the wrong direction
  • Mitral valve prolapse - when one of the valves, the mitral valve, has "floppy" flaps and doesn't close tightly. It's one of the most common heart valve conditions. Sometimes it causes regurgitation.
  • Stenosis - when the valve doesn't open enough and blocks blood flow

Valve problems can be present at birth or caused by infections, heart attacks, or heart disease or damage. The main sign of heart valve disease is an unusual heartbeat sound called a heart murmur. Your doctor can hear a heart murmur with a stethoscope. But many people have heart murmurs without having a problem. Heart tests can show if you have a heart valve disease. Some valve problems are minor and do not need treatment. Others might require medicine, medical procedures, or surgery to repair or replace the valve.
