What is the prevalence of Tetralogy Of Fallot?

Tetralogy of Fallot is the most common form of cyanotic congenital heart disease, occurring in approximately 1 in every 2,500 to 3,000 live births globally. While it is considered a rare condition, advancements in pediatric cardiac surgery have significantly increased the number of individuals living into adulthood with this diagnosis.

What is the incidence and prevalence of Tetralogy of Fallot?

The incidence of Tetralogy of Fallot is estimated at roughly 3 to 4 cases per 10,000 live births, according to data from the National Institutes of Health (NIH) GARD. Because Tetralogy of Fallot requires surgical intervention early in life, the prevalence of the condition is essentially equivalent to the number of survivors of these procedures. It is important to note that global prevalence data can be difficult to track precisely, as access to early diagnosis and surgical care varies significantly between regions, potentially leading to underreporting in lower-resource settings.

Are there demographic differences in Tetralogy of Fallot?

Research indicates that Tetralogy of Fallot affects males and females with roughly equal frequency, though some studies suggest a slight male predominance. While the condition is typically identified during the prenatal period or shortly after birth, the increasing survival rates mean that the community of adults living with Tetralogy of Fallot is growing. Regarding ethnic or geographic distribution, there is no strong evidence suggesting that Tetralogy of Fallot is significantly more common in one specific ethnic group over another.

How does the DiseaseMaps community reflect these statistics?

Clinical data provides only one piece of the puzzle; real-world experiences offer deeper insight into the lifelong journey of living with a heart condition. Currently, 362 individuals with Tetralogy of Fallot have joined the DiseaseMaps.org community to share their experiences. This collective data helps highlight several key aspects of the patient journey:

• The high frequency of early-life surgical interventions.


• The transition from pediatric to adult congenital heart disease (ACHD) care.


• The ongoing need for monitoring and potential re-interventions throughout adulthood.


• The psychological impact of managing a lifelong chronic health condition.

Next steps

• Consult with a board-certified Adult Congenital Heart Disease (ACHD) specialist to monitor your cardiac health.


• Join the Tetralogy of Fallot community at DiseaseMaps.org to connect with others who share your specific medical journey.


• Maintain a comprehensive record of your surgical history and imaging reports to share with your healthcare team.
