The Healers Journal: Understanding Tetralogy of Fallot (TOF): A Hopeful Journey for Newborns
January 13, 2026 | Contributed by Department of Pediatric Cardiac Sciences at Neotia Bhagirathi Woman and Child Care Centre, Newtown
Tetralogy of Fallot (TOF) is a complex heart condition that affects newborns, presenting a combination of four distinct defects. In this blog post, we’ll break down what TOF is, how it impacts the heart, and the hopeful outlook for children diagnosed with this condition. Our team, including some of the best Pediatric cardiologists such as Dr. Aritra Mukherji, Dr. Sanjiban Ghosh, and Pediatric Cardiac Surgeon Dr Nilanjan Dutta, is here to guide you through understanding TOF and the treatments available.
The Four Parts of the Puzzle
TOF is akin to a four-piece puzzle, where each piece disrupts the normal flow of blood through the heart. Let’s take a closer look at these components:
- Narrowed Pulmonary Valve: This acts like a bottleneck, making it harder for blood to flow to the lungs to pick up oxygen.
- Ventricular Septal Defect (VSD): A hole in the wall separating the heart’s lower chambers allows blood to mix, reducing the amount of oxygen-rich blood reaching the body.
- Overriding Aorta: The main artery carrying blood out of the heart (aorta) is positioned abnormally, sometimes even straddling the VSD.
- Right Ventricle Enlargement: Due to the extra workload of pumping blood against the narrowed valve, the right ventricle becomes enlarged.
Symptoms and Treatment
These heart defects can cause symptoms such as fatigue, shortness of breath, and a bluish tint to the skin (cyanosis). Fortunately, with advances in medicine, TOF is typically treated with open-heart surgery to repair the defects. Depending on the child’s condition, this can be done in one surgery or staged procedures.
Our expert team of Pediatric Cardiac Surgeon Dr. Nilanjan Dutta is adept at performing these intricate surgeries. They utilize the latest techniques and technology to ensure the best outcomes for our young patients.
Living a Full Life
Children who undergo successful TOF repair can lead active and healthy lives. Regular check-ups with a cardiologist are crucial to monitor their heart health. While there might be some limitations on strenuous activities in some cases, most children with repaired TOF can participate in sports and other activities they enjoy.
Finding Hope
A TOF diagnosis can be daunting, but remember, medicine has advanced significantly. With proper treatment and care from the best pediatric cardiology team, children with TOF can grow up strong and live fulfilling lives. In the Dept. of Pediatric Cardiac Sciences at Neotia Bhagirathi Woman and Child Care Centre, Newtown, we believe in offering not just treatment, but hope and a pathway to a healthy future for children with TOF. Through collaborations with organizations like Genesis Foundation, a children’s healthcare foundation, we are able to extend advanced pediatric cardiac care to children who may otherwise have limited access to life-saving treatment.
