Uncomplicated Pregnancy with Residual Tetralogy of Fallot Post-Surgery

The most common cyanotic congenital heart disease (CHD) in adults is tetralogy of fallot (TOF), which accounts for 10% of congenital heart anomalies in humans and 75% of cyanotic CHD cases. It is a congenital heart disease that most often requires surgical correction in the first year of life. Corrective surgical treatment began to be applied in the 20th century. It started with a temporary shunt procedure and continued with primary surgical repair. The current approach in infants is valve-sparing techniques. With corrective surgery for TOF, more than 85% of patients can survive into adulthood. Without repair, TOF patients rarely reach adulthood. In this case, the prognosis is poor in pregnant women with CHD, and it is among the leading causes of indirect maternal deaths. The literature indicates that pregnant patients with corrected TOF still have a higher risk compared to otherwise healthy women. Operated fallot, according to the modified World Health Organization maternal cardiovascular risk classification; in terms of maternal risk, it has a mild risk of mortality and moderate risk of morbidity, and the risk of maternal cardiac events is between 5.7-10.5%. Cardiac evaluation should be performed at least once in each trimester throughout pregnancy. In our case, the pregnancy and successful birth without complications of a TOF individual who had corrective surgery in childhood are discussed.
