The Impact of Congenital Heart Defects A normal heart has valves, arteries and chambers that carry the blood in a circulatory pattern: body-heart-lungs-heart-body. When all chambers and valves work correctly, the blood is pumped through the heart, to the lungs for oxygen, back the heart and out to the body for delivery of oxygen. When valves, chambers, arteries and veins are malformed, this circulation pattern can be impaired. Congenital heart defects are malformations that are present at birth. They may or may not have a disruptive effect on a person's circulatory system. Congenital heart defects are structural problems with the heart present at birth. They result when a mishap occurs during heart development soon after conception and often before the mother is aware that she is pregnant.

Congenital heart defects and CCHD Hypoplastic left heart syndrome (HLHS) is a birth defect that affects normal blood flow through the heart. As the baby develops during pregnancy, the left side of the heart does not form correctly. Hypoplastic left heart syndrome is one type of congenital heart defect. Congenital means present at birth.

- A congenital heart defect, also referred to as congenital heart disease or CHD, is a heart problem that is present at birth and is caused by an error in the development of the heart during fetal development.n most cases when a baby is born with a congenital heart defect, there is no known reason for the heart to have formed incorrectly. Scientists know that some types of congenital heart defects can be related to an abnormality of an infant's chromosomes, single gene defects or environmental factors.

patent abnormal persistence of an open lumen in the ductus arteriosus, between the aorta and the pulmonary artery, after birth. The ductus arteriosus is open during prenatal life, allowing most of the blood of the fetus to bypass the lungs, but normally this channel closes shortly before birth. When the ductus arteriosus remains open, it places special burdens on the left ventricle and causes a diminished blood flow in the aorta.

Patent Ductus Arteriosus Patent ductus arteriosus (PDA) is a heart problem that occurs soon after birth in some babies. In PDA, abnormal blood flow occurs between two of the major arteries connected to the heart. Before birth, the two major arteries—the aorta and the pulmonary (PULL-mun-ary) artery—are connected by a blood vessel called the ductus arteriosus.

Congenital Heart Defects ASD (Atrial Septal Defect) Closure Definition Atrial septal defect is an abnormality of the upper chambers of the heart (atria) where the wall between the right and left atria does not close completely. This defect is present at birth (congenital). Causes, incidence, and risk factors. Atrial septal defect (ASD) is a congenital heart defect. In fetal circulation there is normally an opening between the two atria (the upper chambers of the heart) to allow blood to bypass the lungs. This opening usually closes about the time the baby is born.

Overview Truncus arteriosus (TRUNG-kus ahr-teer-e-O-sus) is a rare heart defect that's present at birth (congenital). If your baby has truncus arteriosus, it means that one large blood vessel leads out of the heart.s a result of truncus arteriosus, oxygen-poor blood that should go to the lungs and oxygen-rich blood that should go to the rest of the body are mixed together.

Truncus Arteriosus Click Image to Enlarge. Truncus arteriosus is a congenital (present at birth) defect that occurs due to abnormal development of the fetal heart during the first 8 weeks of pregnancy. The heart begins as a hollow tube, and the chambers, valves, and great arteries develop early in pregnancy.nother congenital heart defect that nearly always occurs with truncus arteriosus is a ventricular septal defect (a hole in the dividing wall (septum) between the two lower chambers of the heart known as the right and left ventricles).

Fetal Echocardiography / Your Unborn Baby's Heart Updated:Jan 8,2015. Congenital heart disease is a problem that occurs with the baby's heart while the baby is still developing. It's seen in approximately 1% of babies born in the United States and is the most common form of birth defect. The baby's heart begins to form immediately after conception and is complete by eight week's gestation. The heart begins as a tube shaped structure that twists and divides to form the heart and heart valves.

Overview Causes of congenital heart defects. Congenital heart defects usually develop while a baby is in the womb. Heart defects can develop as the heart develops, about a month after conception, changing the flow of blood in the heart. Some medical conditions, medications and genes may play a role in causing heart defects.

Genetics of human hydrocephalus Acquired Heart Disease in Children. Heart disease that develops after birth is described as an acquired heart disease. This is in contrast to congenital heart disease, which is present at birth. Acquired heart disease in children may represent diagnoses that do not occur in adults (for example, Kawasaki Disease) or may be similar to conditions present in adults (for example, dilated cardiomyopathy).

Congenital heart defect Most of the known causes of congenital heart disease are sporadic genetic changes, either focal mutations or deletion or addition of segments of DNA. Large chromosomal abnormalities such as trisomies 21, 13, and 18 cause about 5–8% of cases of CHD, with trisomy 21 being the most common genetic cause.

Congenital Heart Defects - Topic Overview Most congenital heart defects affect how blood flows through the heart or through the blood vessels near the heart. Some defects may cause blood to flow in a pattern that isn't normal. Others can completely or partially block blood flow. There are many different types of congenital heart defects. They can be fairly simple, such as a hole between the chambers of the heart or a heart valve that has not formed right. Others are more serious and complex, such as a missing heart valve or heart chamber.

Heart Valve Problems Heart valve problems can be congenital, which means present at birth, or acquired after birth. A heart valve problem is classified as congenital when some factor during fetal development causes the valve to form abnormally. Congenital heart valve disease affects about 1 in 1,000 newborns. Most of these infants have stenosis of either the pulmonary or the aortic valve.

Heart abnormality birth defects In around eight out of 10 cases, the reason for the congenital heart defect is unknown. Some of the known causes of CHD include: Genes – 20 per cent of cases have a genetic cause. Other birth defects – a baby affected by certain birth defects, such as Down syndrome, is more likely to have malformations of the heart. Maternal illness – illness of the mother during pregnancy (for example, rubella – now rare) may increase the risk of congenital heart disorders.
