Congenital Heart Diseases in Children: What Should You Know?


A congenital heart disease of CHD in children refers to an abnormality problem in the strurcture of the heart which is present at birth. The problem can be in the walls or the valves of the heart and the defect can be with veins and arteries. CHD affects about 1,310,000 newborns each year and acoount for a high proportion of infant deaths worldwide. Most of the heart defects do not need treatments but others can be serious. If you see any of the symptoms or if you feel something is not right with your baby then get in touch with your paediatrician immediately.


Symptoms of CHD

The paediatricisn will look for signs to diagnose CHD by giving the child a physical examination. The common symptoms include cyanotic lip, falred nostrils, retraction of lung muscles, swelling of the abdomen, visible veins and arteries in the neck, abnormal sound in the chest, cool skin, slow growth and development in the child, too weak or very strong pulse, less active physically and bue or purple or widened nails.

Types of Congenital heart defects

There are different types of congenital heart defects depending on where the problem lies:

1)    Hole in the heart
a.      Atrial septal defects
b.     Ventricular septal defects
c.      Patent ductus arteriosis

2)    Narrowed or abnormal valves restricting blood flows
a.      Pulmonary stenosis
b.     Aortic stenosis
c.      Ebstein’s anamoly
d.     Pulmonary atresia

3)    Abnormal blood vessels
a.      Transposition of the great arteries
b.     Coarctation of the aorta
c.      Hypoplastic left heart syndrome

4)    Combination of heart defects
a.      Tetralogy of fallout

Reasons for occurrence of heart defects:

The heart begins to take shape during the first six weeks of pregnancy and this is the time when the heart defects occur. Dividingwall in the heart will start to form in fifth week and this is the time when any abnormality in the wall can happen. Most of the CHD’s have no known cause and the scientists are still searching to find out what exactly causes CHD in infants. Scientists think there is a genetic and environmental link to some of the heart defects. Most experts believe there is a link between the congenital heart defects and maternal alcohol consumption and smoking. According to the researchers, the maternal smoking was strongly linked to the pulmonary valve and pulmonary artery anomalies and the atrial septal defects. Children with CHD may continue to have emotional and developmental difficulties even after the treatment. As parents, you should talk to your child’s doctor about how you can help your child to cope up with his/her heart problems.

Treatment for Congenital Heart Diseases:

Most of the heart abnormalities can be corrected with a single operation during early infancy. Most complex abnormalities may require a series of two or three operations that start in the newborn period and are completed at the age of about three years. The children having most complex abnormalities spend the majority of their time in the care of their parents at home and require occasional visits to the paediatric cardiologist as well as the child’s primary care doctor.

Your child will require less invasive procedures that are done in the cardiac catheterization laboratory instead of the operating room. Treatments include balloon angioplasty or valvuloplasty for relieving the obstruction of a blood vessel or a valve obstruction. During these procedures, a paediatric cardiologist will insert a catheter into a blood vessel and then the balloon will be inserted to stretch open the narrow areas of the blood vessels or the heart valve.

A transcatheter device occlusion will be used to close the abnormal openings or the holes within the heart or the blood vessels without requiring surgery. Some abnormalities such as a small or moderate sized ventricular septal defects can be closed or decreased in relative size as the child grows. While waiting for the hole to close, the child will have to take medications and some of them need to take them after the surgery. Whether the treatment is done surgically or medically, the child will need to visit a paediatric cardiologist regularly. At first, these appointments may be fairly frequent but after treatment, you will need to visit sometimes just once a year.
