Is coronary sinus dilatation a risk factor for congenital heart disease?

Coronary sinus dilatation is not a risk of congenital heart disease.

Congenital heart disease refers to structural abnormalities of the heart and great vessels during fetal development. The risk of this disease includes family inheritance, maternal virus infection, and blind maternal medication during pregnancy. It is usually not related to coronary sinus dilatation. However, some congenital heart diseases may cause coronary sinus dilatation, such as coronary arteriovenous fistula, coronary sinus septal defect, etc.

If coronary sinus dilatation is found, further examination, such as cardiac ultrasound and cardiac catheterization, is recommended to determine the cause and extent of dilatation and take appropriate treatment measures.
