Congenital heart defect means an abnormality problem in the structure of the heart. As the term ‘congenital’ suggests, the defect is present at birth, that is, the baby is born along with a defect in his /her heart. The problem can easily be in the walls or the valves of the heart, or the defect can easily be along with the arteries and veins. Congenital heart defects (CHD) affect a lot more compared to 1,310,000 newborns every year and account for a higher proportion of infant deaths international [1]. In India, prevalence of CHD is 19.14 per 1000 individuals, along with 58 percent of CHD cases diagnosed between 0 and five years of age. [2]
Many of the heart defects might not reason treatment. Others can easily be serious. So if you see any sort of of the symptoms offered below or if you feel something is not right along with your baby, get hold of in touch along with your paediatrician immediately.
Symptoms of CHD
The paediatrician will certainly initial look for signs to diagnose CHD by giving the youngster a bodily examination.
Listed below are some common symptoms. [3]
- Flared nostrils: Some defects in the heart can easily pressure the lungs, leading to difficulty in breathing, and the degree of difficulty can easily be determined by the flaring of nostrils as soon as the youngster breathes. Nostrils tend to open wider as soon as the lungs are working harder compared to normal.
- Cyanotic lip: If the inside of the lips turn blue or purple, it means the oxygen levels in the blood is low. reasonable oxygen levels means there is a defect in the heart.
- Visible veins and arteries in the neck: The blood vessels become visible as soon as the heart is not pumping blood efficiently.
- Retraction of lung muscle: It is the inward pulling of lung muscle, that you see as soon as the muscles between or below the ribs are pulled inward, each time the youngster breathes.
- Abnormal sound in the chest: Murmurs, clicks, or beats might indicate the presence of heart defect. Crackle-type noise due to fluid accumulation in the lungs is likewise indicative of heart defect.
- Swelling of the abdomen due to water retention and an enlarged liver, both are signs of CHD.
- Too weak or quite sturdy pulse in the arm or legs can easily likewise be indicative of CHD.
- Cool skin: as soon as there is a problem along with blood flow in the blood vessels or the heart is not pumping enough blood, the physique automatically switches to ‘save’ mode by restricting blood flow to ‘non-essential’ areas such as the hands and legs and skin, thus lowering the temperature of the skin.
- Blue or purple or widened nails.
- Slow growth and development in the child.
- Less energetic physically.
How does the heart work?
Here is a cheat sheet on Exactly how the heart works.
- The heart is divided by walls (septum) in to four chambers.
- Upper two chambers are called left atrium and right atrium, and lower two chambers are called left ventricle and right ventricle.
- Atria receive blood, while ventricles pump blood from the heart.
- Deoxygenated blood from Others portions of the physique goes into right atrium and passes through the tricuspid valve in to the right ventricle.
- From the right ventricle the deoxygenated blood passes in to pulmonary artery through pulmonary valve.
- Pulmonary artery takes the blood to the lungs where oxygen in the lungs attaches to the blood and becomes oxygenated blood.
- Oxygenated blood, then, is carried to the heart by pulmonary vein where it goes into the left atrium.
- From the left atrium, the oxygenated blood passes in to left ventricle through mitral (bicuspid) valve.
- Oxygenated blood, then, goes into the ascending aorta through the aortic valve, which after that takes the oxygenated blood to each and every section of the physique via arteries.
Types of congenital heart defects
There are different types of congenital heart defects depending upon where the problem lies. It is categorized as follows:
I. Hole in the heart
Atrial septal defect: It is a hole in the separating wall of the upper two chambers (atria) of the heart. due to the hole, the oxygen rich blood goes from the left atrium to the right one, rather than the left ventricle. The oxygenated blood mixes along with the deoxygenated blood, so not enough oxygen is circulating in the child’s body. The baby’s skin and fingernails might become blue due to this. The youngster might likewise symptoms of swelling in the legs and shortness of breath. Read a lot more about 7 innovative methods to maintain your child’s heart healthy
Ventricular septal defect: Here, the hole is in the septum separating the two ventricles and blood flows in from the left ventricle to the right one. The hole can easily be small, medium, or large. In case of large holes, lot of blood flows from the left ventricle causing an improve in blood pressure on the right edge of the heart. It makes the heart job harder and can easily lead to heart failure and poor growth.
Patent Ductus Arteriosus: This condition occurs as soon as there is mixing of the blood due to a hole between the pulmonary artery and the aorta. The defect can easily be identified by the heart murmur. Others signs include shortness of breath, and profuse sweating along with exertion.
II. Narrowed or abnormal valves restricting blood flow
Pulmonary stenosis: In this case, the valve that allows the blood to pass from the right ventricle to the pulmonary artery, thickens, stiffens, or fuses together, so the valve cannot open fully. This induces the heart to pump harder, so that blood can easily pass in to the pulmonary artery. In mild cases, the youngster shows no signs and might not reason treatment, yet as soon as the stenosis is severe, the baby can easily feel quite tired, does not feed properly, and shows signs of heavy breathing.

Aortic stenosis: Here, the aortic valve becomes too Slim to permit blood to flow properly from the left ventricle to the aorta. This condition shown no visible signs and Much less severe cases do not reason treatment. Severe forms of aortic stenosis might require catheter procedure or valve surgery. Recent research but suggests valve surgery to be the most effective approach to treat aortic stenosis in infants and newborns. [4]
Ebstein’s anomaly: In this sort of heart defect, the tricuspid valve, that separates the right atrium from right ventricle, is deformed causing the blood to flow spine in to the atrium rather than going to the lungs. In severe cases, surgery could be needed to right the valve.
Pulmonary atresia: Here, the pulmonary valve which regulates blood flow from the right ventricle to the lungs is malformed. Depending on the extent of the defect, complying with treatments are recommended.
- Medicine called Prostaglandin E1
- Heart catheterization
- Open heart surgery
- Heart transplant
III. Abnormal blood vessels
Transposition of the terrific arteries: This is a serious congenital condition where the two main arteries – pulmonary artery and the aorta – are switched in position. Here, the oxygenated blood does not get hold of to the rest of the physique resulting in bluish coloured skin and shortness of breath. Surgery has actually to be done shortly after birth as it can easily prove fatal within six months.
Coarctation of the aorta: It is a heart defect that accounts for five to 8 percent of all heart defects. Here, the aortic wall thickens causing narrowing of the aorta. Coarctation of the aorta induces higher blood stress that must be monitored life long. However, substantial advances in surgical techniques have actually evolved to the point of almost no deaths. [5]
Hypoplastic left heart syndrome: This is a defect in which the left edge of the heart does not produce properly. So, it cannot pump oxygenated blood effectively to the physique parts.
IV. Combination of heart defects
Tetralogy of Fallot:It is a rare, complex defect that is a combination of four heart defects, namely, ventricular septal defect, pulmonary stenosis, overriding aorta (where the aorta appears to arise from both ventricles rather than the left ventricle as it should), and right ventricular hypertrophy (thickening of right ventricular wall). Youngsters along with tetralogy of Fallot prove to signs of cyanosis (blue tinge to skin, nails, and lips), and become over-tired or limp. An open heart surgery is the treatment for this heart defect. as soon as the surgery is performed depends on Exactly how far the pulmonary artery is blocked. Usually the surgery is done within initial 6 months of the baby’s age. along with the greatly improved surgical techniques, most Youngsters mature in to adulthood, yet they would certainly require lifelong medical care.

Why do heart defects occur?
The heart begins to take shape in the initial six weeks of pregnancy, so that is the time as soon as the heart defects occur. For example, the separating wall in the heart starts to form in week-5, so that is as soon as any sort of abnormality in the wall can easily happen. Most of the CHDs have actually no known trigger and scientists are still searching to discover out just what exactly induces CHD. However, scientists believe that there is a genetic and environmental link to some heart defects. Lots of experts believe there is likewise a link between congenital heart defects, and maternal smoking and alcohol consumption. Even though recent studies have actually not found a little drinking to be associated along with CHD [6], smoking is surely linked to CHD. Researchers found that maternal smoking was most strongly associated along with pulmonary valve and pulmonary artery anomalies, and atrial septal defects. [7]
Children along with congenital heart defect might go on to have actually emotional and developmental difficulties even after treatment. As a parent, you can easily talk to your child’s doctor regarding Exactly how you can easily insight your youngster cope along with his /her problems.
