Q. What are the heart valves?
A. There are four valves which control the blood flow through the heart. They all consist of two or three flaps which swing open to allow blood through with each heart beat, and swing closed to prevent blood going back in the wrong direction.
Deoxygenated (blue) blood returning from the body collects in the right atrium. It flows to the right ventricle through the 'tricuspid valve'. It is then pumped through the 'pulmonary valve' into the pulmonary artery on its way to the lungs. Oxygenated (red) blood returning from the lungs collects in the left atrium and flows through the 'mitral valve' into the left ventricle. It is then pumped through the 'aortic valve' into the aorta and to the body.
Q. What is meant by the term 'congenital heart disease?
A. The phrase 'congenital heart disease' refers to the various abnormalities of the heart which are present at birth. Other words, such as disorder, defect, condition, or problem, may be used instead of disease.
Q. How common are congenital heart problems?
A. Abnormalities of the heart are present in nearly 10 in every 1,000 babies born. Some of these are mild and cause no significant disturbance to heart function. In many cases, such minor problems need no treatment and do not affect the life or the health of the child. More serious abnormalities are present in about five of these ten individuals with congenital heart problems.
