What is the prognosis of congenital heart disease?
The prognosis for CHF is based on five-year mortality (death) rates. This measure is used to estimate short- and long-term survival rates from the time that your CHF is diagnosed and treatment begins. Some 6.2 million adults in the United States have been diagnosed with heart failure. The five-year survival rate is about 50% for all stages.

The most common form of cyanotic congenital heart disease in adults is tetralogy of Fallot. Other complex conditions seen in adults include univentricular hearts, Ebstein's anomaly of the tricuspid valve, and corrected transposition of the great vessels.
What is the most serious congenital heart disease?
Critical congenital heart disease About 25% of all congenital heart defects are considered critical, meaning they will require surgery or a procedure within a baby's first year of life. Hypoplastic left heart syndrome is the most involved and complex of all congenital heart diseases.
What is the most common cause of cyanosis?
Cyanosis is usually caused by problems of the heart, lungs, or blood. Some of the heart conditions that can cause a child to have cyanosis are: truncus arteriosus. total anomalous pulmonary venous return.
What is a critical cyanotic congenital heart defect?
Cyanotic heart disease is any heart defect present at birth that reduces the amount of oxygen delivered to your body. It's also called critical congenital heart disease or CCHD. There are many types of CCHD, and most people need oxygen therapy and surgery to survive.
What is the most common congenital heart defect in children?
The most common type of heart defect is a ventricular septal defect (VSD).
What are the 4 abnormalities in tetralogy of Fallot?
Tetralogy of Fallot is a combination of four congenital heart defects. The four defects are a ventricular septal defect (VSD), pulmonary stenosis, a misplaced aorta and a thickened right ventricular wall (right ventricular hypertrophy). They usually result in a lack of oxygen-rich blood reaching the body.
Is tetralogy of Fallot acyanotic or cyanotic?
Tetralogy of Fallot is the most common form of cyanotic congenital heart disease. Cyanosis is the abnormal bluish discoloration of the skin that occurs because of low levels of circulating oxygen in the blood.

What are critical congenital heart diseases?
Critical congenital heart disease (CCHD) is a term that refers to a group of serious heart defects that are present from birth. These abnormalities result from problems with the formation of one or more parts of the heart during the early stages of embryonic development.
What are the 4 main causes of birth defects?
Smoking, drinking alcohol, or taking certain drugs during pregnancy. Having certain medical conditions, such as being obese or having uncontrolled diabetes before and during pregnancy. Taking certain medications, such as isotretinoin (a drug used to treat severe acne). Having someone in your family with a birth defect.
What are the 4 defects found in tetralogy of Fallot?
Tetralogy of Fallot is a combination of four congenital heart defects. The four defects are a ventricular septal defect (VSD), pulmonary stenosis, a misplaced aorta and a thickened right ventricular wall (right ventricular hypertrophy). They usually result in a lack of oxygen-rich blood reaching the body.
What is cyanotic and Acyanotic heart disease?
Cyanotic congenital heart disease: Cyanotic heart disease involves heart defects that reduce the amount of oxygen delivered to the rest of the body. Acyanotic congenital heart disease: With this type of heart defect, blood contains enough oxygen, but it's pumped throughout the body abnormally.
Is ToF a cyanotic heart disease?
Infants with tetralogy of Fallot can have a bluish-looking skin color―called cyanosis―because their blood doesn't carry enough oxygen. At birth, infants might not have blue-looking skin, but later might develop sudden episodes of bluish skin during crying or feeding.
What is Eisenmenger syndrome?
In Eisenmenger syndrome, there is irregular blood flow in the heart and lungs. This causes the blood vessels in the lungs to become stiff and narrow. Blood pressure rises in the lungs' arteries (pulmonary arterial hypertension). Eisenmenger syndrome permanently damages the blood vessels in the lungs.
How common is congenital heart disease?
Congenital heart disease (CHD) affects 8 to 9 per 1000 live births, and approximately 25% are considered CCHD. The incidence of CHD increase to 2% to 6% for a second pregnancy after the birth of a child with CHD or if a parent is affected. Tetralogy of Fallot (TOF) is the most common CCHD (5% of all CCHD). Transposition of the great arteries (TGA) is the second most common CCHD (approximately 2% of all CCHD), and it is the most common CCHD manifesting in the first week after birth. It is estimated that 35% of infant deaths due to congenital malformations are related to cardiovascular anomalies.
What is the most common birth defect in children?
Congenital heart disease ( CHD) are structural abnormalities of the heart or intrathoracic great vessels occurring during fetal development. CHD is the most common type of birth defect and the leading cause of death in children with congenital malformations. CHD can be subdivided in non-cyanotic CHD and cyanotic CHD which is also called critical congenital heart disease (CCHD). CCHD can be further classified into 3 different type of lesions: right heart obstructive lesions, left heart obstructive lesions, and mixing lesions.[1][2][3][4]
Why is CCHD silent?
CCHD is silent in fetal life because fetus receives oxygenated blood from the placenta and either the FO or DA can increase systemic blood flow. After DA and FO closure soon after birth, most CCHD become symptomatic. Cyanosis may be caused by persistence of fetal circulation, right-to-left shunting across the FO and ductus DA in the presence of pulmonary outflow tract obstruction or persistent pulmonary hypertension of the newborn.
What is the test for CCHD?
Hyperoxia test is the initial method to distinguish CCHD from pulmonary disease. The test consists in measuring an arterial blood gas at room air and 100% inspired oxygen after 10 minutes. Neonates with congenital heart disease are usually not able to increase PaO2 above 100 mm Hg during 100% oxygen administration. In patients with pulmonary disease, PaO2 generally increased greater than or equal to 100 mm Hg with 100% oxygen as ventilation-perfusion discrepancies are overcome. A positive result indicates the cardiac origin and further cardiac workup is indicated to rule out CCHD.
What is reverse cyanosis?
Reverse cyanosis, lower oxygen saturation in the right hand, is a manifestation of TGA with concurrent CoA or IAA. Positive pulse oximetry screen will require prompt evaluation, including 4-limb blood pressure measurement, chest radiography, ECG, and echocardiography.
Which hand is recommended for CCHD screening?
CCHD screening will only identify cardiac lesions with the right to left shunt and cyanosis. Screening is recommended in the right hand and either foot. Positive screen result includes one of the following:
Is CHD a genetic disorder?
CCHD is usually isolated and sporadic, but it can also be associated with genetic syndromes. Approximately 15% to 20% of infants with CCHD are related to known chromosomal abnormalities, most of these are aneuploidies (trisomy 21, 13, and 18 and Turner syndrome). Potential environmental risk factors include maternal illnesses, including diabetes and phenylketonuria, maternal exposure to toxins or drugs and viral infections during pregnancy.
What is a congenital heart disease?
Congenital heart disease (CHD) is any abnormal heart structure (defect) present at birth. There are two types of CHD:
Which artery carries oxygen-poor blood from the right side of the heart to the lungs to be oxygen?
Pulmonary stenosis: The pulmonary artery carries oxygen-poor blood from the right side of the heart to the lungs to be oxygenated. The pulmonary valve sits between the right side of the heart and the pulmonary artery. When the pulmonary valve becomes narrowed and doesn’t open well, it's called pulmonary stenosis.
What is the hole in the heart called?
Atrial septal defect: An atrial septal defect (ASD) is a hole in the wall that separates the heart’s two upper chambers, called the atria. Most ASDs don't close on their own. Tiny ASDs can often be left alone, but larger ASDs may require a procedure or heart surgery to close them.
What is a ventricular septal defect?
Ventricular septal defect: A ventricular septal defect (VSD) is like an atrial septal defect, but it’ s a hole in the wall that separates the heart’s two lower chambers (the ventricles). VSD is the most common congenital heart defect. Many of these holes can close on their own, but some may require a procedure or a surgery to close them.
What is it called when the aortic valve is narrowed?
Aortic stenosis: The aorta is the main artery that carries blood away from your heart to the rest of the body. The aortic valve sits between the heart and aorta. It opens and closes with each heart cycle to let blood out of the heart and keep blood from leaking back into the heart. When the aortic valve becomes narrowed and doesn’t open well, it’s called aortic stenosis.
Can acyanotic heart disease shorten your life?
But as you get older, a congenital heart defect may cause problems that can affect your lifestyle . Some complications, such as heart failure, can shorten your life span.
Can a baby have a heart murmur?
Babies born with acyanotic heart disease may have a heart murmur, but others may not have any signs at first. Even if they don’t cause any problems at first, these defects can cause problems over time.
