Can you have a baby if you once had open heart surgery?

For sure: Definitely. If your overall condition is otherwise good enough to have a baby, having had ohs isn't a factor.

Heart surgery: Definitely. As long your ovaries and uterus have not been compromised during complications of a congenital heart defect, or other heart conditons necessitating heart surgery, e.G, shock, poor blood oxygenation, you can still successfully have children.

Depends: For many, this just fixes things enough that they will have a normal life thereafter, including having children. For others with a complex congenital defect, it just gets them stable enough to survive. Open heart surgery by itself does not end a persons potential to be a mom.The condition that lead to it or the condition afterward would decide that.

Depends : Your surgeon and Cardiologist are in best place to advise you. Pregnancy will task your heart hence should be undertaken with close monitoring
