Congenital Heart Disease: Definition

Congenital heart disease is a term used to describe a range of heart defects that are present at birth. These defects can affect the walls, valves, or blood vessels of the heart, disrupting the normal flow of blood through the heart. Some children may have mild forms of congenital heart disease that require little to no treatment, while others may have more severe cases that need immediate medical intervention. Understanding the specific type of heart defect your child has is essential in determining the appropriate course of action for treatment.

Congenital Heart Disease Types

There are many congenital heart defects, ranging from simple to complex. Here are some of the most common ones:

Septal Defects

Atrial Septal Defect (ASD)

An atrial septal defect is a hole in the wall (septum) that divides the heart's upper chambers (atria). This defect allows oxygen-rich blood from the left atrium to mix with oxygen-poor blood in the right atrium, potentially causing overcirculation of the lungs and enlargement of the right side of the heart.

Ventricular Septal Defect (VSD)

A ventricular septal defect is a hole in the wall separating the lower chambers of the heart (ventricles). This defect allows oxygen-rich blood from the left ventricle to mix with oxygen-poor blood in the right ventricle, which can lead to pulmonary hypertension and heart failure if not treated.

Valve Defects

Pulmonary Valve Stenosis

Pulmonary valve stenosis narrows the pulmonary valve, reducing blood flow from the right ventricle to the lungs. This can cause the right ventricle to work harder, potentially leading to right ventricular hypertrophy and heart failure.

Aortic Valve Stenosis

Aortic valve stenosis is the narrowing of the aortic valve, affecting blood flow from the left ventricle to the rest of the body. This can cause the left ventricle to thicken and may lead to heart failure if severe.

Complete and Complex Defects

Tetralogy of Fallot

Tetralogy of Fallot is a combination of four heart defects: ventricular septal defect, pulmonary valve stenosis, right ventricular hypertrophy, and an overriding aorta. These defects reduce oxygen in the blood flowing to the rest of the body, causing cyanosis and requiring surgical correction.

Transposition of the Great Arteries (TGA)

In the transposition of the great arteries, the two main arteries leaving the heart are reversed. The aorta arises from the right ventricle, and the pulmonary artery arises from the left, causing oxygen-poor blood to circulate. In contrast, oxygen-rich blood circulates through the lungs. This condition requires immediate medical intervention after birth.

Hypoplastic Left Heart Syndrome (HLHS)

Hypoplastic left heart syndrome is a severe defect where the left side of the heart is underdeveloped. This affects the heart's ability to pump blood effectively to the body and requires a series of surgeries or a heart transplant for survival.

Other Notable Defects

Patent Ductus Arteriosus (PDA)

Patent ductus arteriosus occurs when the ductus arteriosus, a blood vessel that bypasses the lungs in fetal circulation, fails to close after birth. This allows oxygen-rich blood from the aorta to mix with oxygen-poor blood in the pulmonary artery, straining the heart and increasing lung pressure.

Coarctation of the Aorta (CoA)

Coarctation of the aorta is a narrowing of the aorta, the large blood vessel that carries oxygen-rich blood from the heart to the rest of the body. This narrowing forces the heart to pump harder to get blood through the aorta, potentially leading to hypertension and heart damage.

What Causes Congenital Heart Disease?

The exact cause of congenital heart disease is often unknown, but several factors can contribute to its development.

Genetic Factors

Genetics plays a significant role in the development of CHD. Children with a family history of heart defects are more likely to have CHD. Specific genetic syndromes, such as Down syndrome or ADHD, are also associated with higher rates of congenital heart defects.

Environmental Influences

Environmental factors during pregnancy can influence the development of the fetal heart. These include maternal illnesses, medications, and exposure to harmful substances like alcohol and drugs.

Maternal Health Conditions

Certain health conditions in the mother, such as diabetes or obesity, can increase the risk of CHD in the baby. Poorly controlled blood sugar levels in diabetic mothers are particularly associated with heart defects.

Congenital Heart Disease: Signs & Symptoms

The symptoms of CHD can vary widely depending on the type and severity of the defect. Some children may show symptoms at birth, while others may not exhibit signs until later in childhood.

Common Symptoms

• Cyanosis: A bluish tint to the skin, lips, and fingernails due to low oxygen levels.
• Rapid Breathing: Difficulty breathing or shortness of breath, especially during feeding.
• Poor Feeding: Infants may tire quickly during feeding and fail to gain weight properly.
• Heart Murmurs: Unusual sounds heard during a heartbeat, often detected by a doctor during a physical exam.
• Fatigue: Older children may experience fatigue, especially during physical activities.

Less Common Symptoms

• Swelling in the legs, abdomen, or areas around the eyes.
