Does anyone have experience with PDA closures?

Multiple options. A PDA is vessel that is normal in the fetus but should close soon after delivery. Unfortunately the right answer to when and how to close a PDA is dependent on the situation. Usually the least invasive to get the job done. Many close on their own, so watchful waiting, or fluid restriction may be the right answer. Alternatively, medicines, catheter procedures, or open surgery may be done depend.
Not a big deal. This us the easiest operation and is safely performed. Most of the ducts on older infants > 10lb can be closed with catheter techniques. Mostly as outpatient procedures without any residues and a normal quality of life and normal life expectancy.
