Children make a family complete. At different times, they can make you laugh, make you cry, make you proud or make you angry, but they will always bring love and joy into your life. A child’s life is truly precious but it is also very fragile, especially if the child has heart disease.
Heart disease in children is a complicated issue with many different conditions included under this umbrella term. Because it often shows no symptoms in the early stages, it is difficult to detect, and because some causes are not known, it can be difficult to prevent. However, risk factors to look out for include viral infections, rubella, genetic disorders, or drug abuse by the mother during pregnancy.
Heart disease in children can be divided into two categories: congenital heart disease and acquired heart disease. Of these two, congenital heart disease is by far the more common. It is estimated that between 8 and 10 newborns out of every 1,000 births has a heart defect. In some cases, the symptoms may not appear until the child is already past his or her fifth birthday. However, the first symptoms will usually be observed before the child reaches 2 years of age.
Just as heart disease is divided into two categories, so congenital heart disease can also be further grouped into cyanotic and non-cyanotic conditions.
In cyanotic congenital heart disease, the heart and blood vessels are subject to an abnormality which causes “blue” and “red” blood to mix and restrict the flow of oxygen through the body. The most noticeable symptoms are the skin and mouth turning bluish or purplish. However, the baby will also become very easily fatigued and will cry constantly, especially when being breastfed. If the condition remains untreated, it can lead to developmental problems due to the lack of oxygen in the blood.
In non-cyanotic congenital heart disease, the skin does not turn blue because the blue and red blood do not mix. The usual causes are a congenital defect in the development of either the heart or the blood vessels and there may be a hole in the heart valves. In babies, the symptoms include a need to take regular breaks to breathe during breastfeeding, while older infants and children will experience fatigue and labored breathing during physical activity.
The first step to diagnosing congenital heart conditions typically involves a review of the medical history of the individual and their family. If risk factors are identified, then this may lead to a clinical examination including ultrasound, coronary angiogram or magnetic resonance imaging (MRI).
Diagnosis tends to be easier in adults as they can describe their symptoms. However, it is difficult to know when babies are experiencing genuine symptoms as they can sometimes just be seeking attention. As a result, it is extra important to watch for the following warning signs in babies and young infants.
In many cases, treatment with medication or surgery can lead to a complete cure. Even in cases where a full cure is not possible, the treatment will provide the children with a better quality of life.
While surgery can be performed on children of all ages, it is generally avoided in newborns unless a medical implication necessitates immediate action. Advances in medical technology have made this a far less risky operation than in the past. In most cases, however, the doctor will wait until the baby has grown and gained weight before performing the surgery if it isn’t urgent.
After surgery, patients will typically be monitored for up to two weeks, depending on the particular procedure performed and the patient’s condition. If there are no complications, the patient should recover fully in just 2 to 3 months.
If you observe any of the warning signs mentioned in this article, or if you have any concern at all, it is always better to consult a pediatrician. If a heart condition is detected, it can receive immediate treatment. If no condition is detected, then you can rest easily. Don’t take a risk with heart conditions. If in doubt, consult a pediatrician immediately.
