Tetralogy of Fallot is an 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.
Tetralogy of Fallot (TOF) needs to be treated timely 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.
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
Causes
There are four structural issues with the heart in tetralogy of Fallot:
Risk Factors
Risk factors include:
Complications
The following complications could occur:
To assist in lowering your child's overall risk of birth abnormalities, you can do the following:
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.

India was chosen for the following reasons:
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%.
Tetralogy of Fallot treatment in India usually has a high success rate, between 95% and 98%, due to innovative surgical procedures, highly qualified cardiologists, and top-notch medical facilities. India provides a dependable and efficient treatment option for TOF, with skilled surgeons and extensive post-surgery care. It is a desirable location for patients looking for premium care at a reasonable price.
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:
Even though tetralogy of Fallot surgery restores a standard blood flow path, additional problems may still arise, such as:
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.
