The symptoms of congenital heart disease in infants and children may include: A bluish tint to the skin, fingernails, and lips (doctors call this cyanosis, a condition caused by a lack of oxygenated blood) Fast breathing and poor feeding. Poor weight gain. Lung infections. An inability to exercise.
Congenital heart disease, or a congenital heart defect, is a heart abnormality present at birth. The problem can affect: There are numerous types of congenital heart defects. They can range from simple conditions that don’t cause symptoms to complex problems that cause severe, life-threatening symptoms.
The word “congenital” means existing at birth. The terms “congenital heart defect” and “congenital heart disease” are often used to mean the same thing, but “defect” is more accurate. A congenital heart defect (CHD) results when the heart, or blood vessels near the heart, don’t develop normally before birth. Learn more about CHD.
Congenital heart disease (congenital heart defect) is one or more abnormalities in your heart's structure that you're born with. This most common of birth defects can alter the way blood flows through your heart.
Congenital heart disease. Congenital heart disease (CHD) is a problem with the heart's structure and function that is present at birth. CHD can describe a number of different problems affecting the heart. It is the most common type of birth defect. CHD causes more deaths in the first year of life than any other birth defects.
Cyanotic heart disease refers to a group of many different heart defects that are present at birth (congenital). They result in a low blood oxygen level 73) . Cyanosis refers to a bluish color of the skin and mucous membranes.
Tetralogy of Fallot (TOF) is a type of heart defect present at birth. Symptoms include episodes of bluish color to the skin. When affected babies cry or have a bowel movement, they may develop a "tet spell" where they turn very blue, have difficulty breathing, become limp, and occasionally lose consciousness. Other symptoms may include a heart murmur, finger clubbing, and easy tiring upon breastfeeding. The cause is typically not known. Risk factors include a mother who uses alcohol, has diabetes, is over the age of 40, or gets rubella during pregnancy. It may also be associated with Down syndrome. Classically there are four defects: pulmonary stenosis, narrowing of the exit from the right ventricle a ventricular septal defect, a hole between the two ventricles right ventricular hypertrophy, thickening of the right ventricular muscle an overriding aorta, which allows blood from both ventricles to enter the aortaTOF is typically treated by open heart surgery in the first year of life. Timing of surgery depends on the baby's symptoms and size. The procedure involves increasing the size of the pulmonary valve and pulmonary arteries and repairing the ventricular septal defect. In babies who are too small a temporary surgery may be done with plans for a second surgery when the baby is bigger. Most people who are affected live to be adults. Long-term problems may include an irregular heart rate and pulmonary regurgitation. TOF occurs in about 1 in 2,000 newborns. Males and females are affected equally. It is the most common complex congenital heart defect. It was initially described in 1671 by Niels Stensen. A further description was published in 1888 by the French physician Étienne-Louis Arthur Fallot, after whom it is named. The first surgical repair was carried out in 1954.
A congenital heart defect (CHD), also known as a congenital heart anomaly or congenital heart disease, is a problem in the structure of the heart that is present at birth. Signs and symptoms depend on the specific type of problem. Symptoms can vary from none to life-threatening. When present they may include rapid breathing, bluish skin, poor weight gain, and feeling tired. It does not cause chest pain. Most congenital heart problems do not occur with other diseases. Complications that can result from heart defects include heart failure. The cause of a congenital heart defect is often unknown. Certain cases may be due to infections during pregnancy such as rubella, use of certain medications or drugs such as alcohol or tobacco, parents being closely related, or poor nutritional status or obesity in the mother. Having a parent with a congenital heart defect is also a risk factor. A number of genetic conditions are associated with heart defects including Down syndrome, Turner syndrome, and Marfan syndrome. Congenital heart defects are divided into two main groups: cyanotic heart defects and non-cyanotic heart defects, depending on whether the child has the potential to turn bluish in color. The problems may involve the interior walls of the heart, the heart valves, or the large blood vessels that lead to and from the heart. Congenital heart defects are partly preventable through rubella vaccination, the adding of iodine to salt, and the adding of folic acid to certain food products. Some defects do not need treatment. Others may be effectively treated with catheter based procedures or heart surgery. Occasionally a number of operations may be needed, or a heart transplant may be required. With appropriate treatment, outcomes are generally good, even with complex problems. Heart defects are the most common birth defect. In 2015 they were present in 48.9 million people globally. They affect between 4 and 75 per 1,000 live births depending upon how they are diagnosed. About 6 to 19 per 1,000 cause a moderate to severe degree of problems. Congenital heart defects are the leading cause of birth defect-related deaths. In 2015 they resulted in 303,300 deaths down from 366,000 deaths in 1990.
A cardiac shunt is a pattern of blood flow in the heart that deviates from the normal circuit of the circulatory system. It may be described as right-left, left-right or bidirectional, or as systemic-to-pulmonary or pulmonary-to-systemic. The direction may be controlled by left and/or right heart pressure, a biological or artificial heart valve or both. The presence of a shunt may also affect left and/or right heart pressure either beneficially or detrimentally.
