Congenital Heart Disease (CHD) refers to a range of birth defects that affect the normal workings of the heart. These defects can involve the interior walls of the heart, the heart valves, or the large blood vessels that carry blood to and from the heart. CHD is the most common type of birth defect, affecting approximately 1 in 100 live births.
Classification
Congenital heart defects are classified based on the specific structural abnormalities present. The main categories include:
Cyanotic Defects
Cyanotic heart defects result in a decrease in the amount of oxygen delivered to the body, leading to cyanosis, a bluish tint to the skin, lips, and nail beds. Common cyanotic defects include:
Acyanotic Defects
Acyanotic heart defects do not typically cause cyanosis but can lead to other complications such as heart failure. Examples include:
- Ventricular septal defect (VSD)
- Atrial septal defect (ASD)
- Patent ductus arteriosus (PDA)
Causes
The exact cause of congenital heart disease is often unknown, but it is believed to be due to a combination of genetic and environmental factors. Some known risk factors include:
- Genetic syndromes such as Down syndrome
- Maternal conditions like diabetes and rubella infection during pregnancy
- Exposure to certain medications or substances during pregnancy
Symptoms
Symptoms of congenital heart disease can vary widely depending on the type and severity of the defect. Common symptoms include:
- Cyanosis
- Shortness of breath
- Fatigue
- Heart murmur
- Poor feeding and growth in infants
Diagnosis
Diagnosis of congenital heart disease typically involves a combination of physical examination and diagnostic tests. These may include:
- Echocardiogram: An ultrasound of the heart to visualize its structure and function
- Chest X-ray: To assess the size and shape of the heart and lungs
- Magnetic Resonance Imaging (MRI): Provides detailed images of the heart's anatomy
- Cardiac catheterization: Invasive procedure to measure pressures and oxygen levels in the heart chambers
Treatment
Treatment for congenital heart disease depends on the specific defect and its severity. Options include:
Surgical Intervention
Many congenital heart defects require surgical correction. Common procedures include:
- Open-heart surgery to repair or replace heart valves or close septal defects
- Arterial switch operation for transposition of the great arteries
Catheter-Based Procedures
Less invasive than surgery, these procedures use catheters to repair defects:
- Balloon angioplasty to open narrowed blood vessels
- Device closure of septal defects
Medication
Medications may be used to manage symptoms or prevent complications:
- Diuretics to reduce fluid overload
- Beta-blockers to control heart rate
Prognosis
The prognosis for individuals with congenital heart disease varies widely. Advances in medical and surgical treatment have significantly improved outcomes, allowing many individuals to lead normal, active lives. However, lifelong follow-up with a cardiologist is often necessary.
Prevention
While not all cases of congenital heart disease can be prevented, certain measures can reduce risk:
- Prenatal care and screening
- Avoidance of alcohol and certain medications during pregnancy
- Management of maternal health conditions
