Hello! Doctor would like to answer the question: "Is the pulmonary valve after congenital heart surgery tetralogy of Fallot permanent?" Your answer is as follows :
Tetralogy of Fallot is a complex cyanotic congenital heart disease that repairs multiple parts of the heart. In which the right ventricular outflow tract plays an important role. In Fallot's disease, there is a case where the pulmonary valve is narrowed but can be repaired and widened.
In this case, the pulmonary valve will persist for a long time, but there is also a chance of restenosis. For cases where the pulmonary valve is too narrow or hypoplastic, doctors have to make an artificial valve, in this case the valve will calcify and narrow after 8-10 years and need intervention.
You should take your child to be examined at a reputable medical facility or one of the hospitals under the Vinmec Health System nationwide for an echocardiogram and better advice
Thank you for your trust and question to Vinmec. Best regards!
