What is Tetralogy of Fallot?

Tetralogy of Fallot is a rare congenital cardiac disease. The disease causes four distinct heart issues in a newborn.

The structure of the heart is impacted by several cardiac issues. Blood flow via the heart and to the rest of the body is changed by the disease.

Surgery is required for those with tetralogy of Fallot to repair their hearts. They will require lifelong routine health examinations.

What is the Importance of Timely Treatment?

Tetralogy of Fallot (TOF) needs to be treated on time to avoid potentially fatal consequences such as cardiac failure, arrhythmias, and stroke. Quick action guarantees adequate blood flow throughout the body, enhances oxygenation, and lowers the risk of cyanosis.

Additionally, it promotes healthy growth and development, especially in children, avoids irreversible damage to the heart muscle, and improves overall heart function.

It is essential to treat TOF as soon as possible because it might result in long-term health problems, such as chronic illnesses and reduced physical activity, if treatment is delayed.

What are the Common Symptoms of Tetralogy of Fallot?

The degree of blockage in the passage of blood from the heart to the lungs determines the symptoms of tetralogy of Fallot. Among the symptoms could be

  • Grey or blue skin
  • Difficulty breathing and fast breathing, mainly when eating or exercising
  • Difficulty putting on weight
  • Being fatigued quickly while playing or working out
  • Irritability
  • Crying over extended intervals
  • Fainting

Causes, Risk Factors and Complications of Tetralogy of Fallot

Causes

There are four structural issues with the heart in tetralogy of Fallot:

  • Pulmonary valve stenosis usually happens when the valve that connects the heart and lungs narrows.
  • A ventricular septal defect is a hole between the heart's bottom chambers.
  • Alteration of the major artery in the body.
  • Right ventricular hypertrophy is the thickening of the heart's right bottom chamber.
  • Other issues affecting the aorta or heart arteries are seen in some individuals with tetralogy of Fallot. A hole between the heart's upper chambers, an atrial septal defect, may also exist.

Risk Factors

Risk factors include:

  • Family history
  • Contracting a virus when pregnant.
  • Consuming alcoholic beverages during pregnancy.
  • Consuming unhealthy food while pregnant.
  • Smoking when expecting.
  • Mother is older than thirty-five.
  • The infant may have DiGeorge syndrome or Down syndrome.

Complications

The following complications could occur:

  • Blood flows backwards through a heart valve.
  • Irregular pulses.
  • An incision in the heart that remains after surgery.
  • Variations in the heart chambers' dimensions.
  • Aortic root dilatation is the swelling of a portion of the aorta.
  • Unexpected cardiac death.
  • Infectious Endocarditis

Treatment options for tetralogy of Fallot

Open-heart surgery: Complete tetralogy of Fallot corrective surgery includes patching the ventricular septal defect, excising the thickened proper ventricle tissue, and enlarging the pulmonary valve.

Tof repair: For infants with tetralogy of Fallot, tof repair is a short-term procedure that involves creating a shunt between the aorta and lung arteries. This procedure, frequently used when a newborn is born prematurely or underdeveloped, increases blood supply to the lungs.


Cost Start From USD 19000 - USD 28000Explore Options

  • Prenatal Diagnosis
    • Pregnancy ultrasound: Your healthcare practitioner can use a fetal ultrasound imaging of the fetus's heart between weeks 18 and 22 of your pregnancy to determine whether the heart's anatomy is normal.
  • Postnatal Diagnosis
    • Echocardiogram: This test creates images of the heart using sound waves.
    • Chest X-ray: An X-ray of your baby's chest can reveal the size and form of their heart and lungs.
    • Electrocardiogram (EKG): An EKG measures a heartbeat's electrical activity
    • Cardiac catheterisation: This test aids in diagnosing or managing specific cardiac disorders. It could be used to schedule surgery.
    • Oxygen level measurement: The blood's oxygen content is rapidly measured by a tiny pulse oximetry test applied to a finger or toe.

Tetralogy of Fallot rehabilitation options include:

  • Physical Therapy: Following surgery, physical therapy aids patients in regaining their cardiovascular health, strength, and mobility. It might entail strength and endurance-building workouts.
  • Cardiac Rehabilitation: This type of rehabilitation, frequently designed for older kids, teens, or adults, emphasises support, education, and exercise to enable patients to resume their regular activities.
  • Breathing Exercises: Following surgery, pulmonary rehabilitation may be utilised in some situations to enhance lung function and oxygenation.

Few medications are used to treat Tetralogy of Fallot to control symptoms, enhance cardiac function, and avoid complications after surgery.

Frequently Asked Questions

Babies assigned male at birth (AMAB) are more likely to get tetralogy of Fallot. Tetralogy of Fallot is also frequently observed by medical professionals in infants with Down syndrome or other chromosomal abnormalities.

Thirty per cent of those with tetralogy of Fallot survive until age ten without a repair, and five per cent survive until age forty. The 30-year survival rates for those with repair vary from 68.5% to 90.5%.

Treatment for Ventricular Septal Defect (VSD) has a success rate in Malaysia. While device closures have a 96% success rate, spontaneous closure happens in 55% of newborns. Although results vary depending on personal characteristics such as age, the severity of the illness, and general health, surgical procedures also show promising results.

Is the treatment for tetralogy of Fallot in Malaysia affordable?

Yes, the cost of Tetralogy of Fallot therapy in Malaysia is lower than in many Western nations, without compromising the quality of care or the expertise of medical professionals.

Tet spells are episodes, usually during or after feeding, screaming, or pooping, when a baby's oxygen level abruptly drops. Babies may have a lot of sleep and feel exhausted following these episodes, lasting from a few minutes to several hours.

You can support your infant during tet episodes until surgery. Put your infant in a squatting position (pressing their knees to their chest) if they have difficulty breathing. To enhance blood flow, your doctor may prescribe beta-blockers and additional oxygen.

Additional actions you can do to support your child include ensuring that they:

  • Are consuming adequate fluids.
  • Are not exercising too hard.
  • They are taking medications as directed by their doctor.

Even though tetralogy of Fallot surgery restores a standard blood flow path, additional problems may still arise, such as:

  • Dental care is crucial because you may be at an increased risk of developing endocarditis, an infection of the heart.
  • Tetralogy of Fallot may cause decreased growth and development in infants. They might benefit from occupational, speech, or physical therapy.
  • You might be more susceptible to an irregular heartbeat, called arrhythmia.
  • There is a greater chance of miscarriage, and your doctor might need to evaluate your heart before you become pregnant.

Your child will require routine follow-up sessions with a pediatric cardiac specialist following tetralogy of Fallot surgery. Into adulthood, this care will continue.

Although uncommon, it occasionally happens for someone to reach adulthood without surgical repairs. To avoid further difficulties or unexpected death, specialists advise a complete surgical repair.

Most people with corrected tetralogy of Fallot can safely carry a pregnancy in alignment with the proper prenatal treatment and close monitoring.

A specialist in adult congenital heart disease should be seen by anyone who has had surgery to repair tetralogy of Fallot and is thinking about getting pregnant. An obstetrician who treats patients with unique medical issues should also be consulted.
