Older children with moderate or large PDAs might benefit fromkeyhole closure johnson gold the PDA with an umbrella device. In some children where the PDA is small but a clear and distinctive murmur can be heard your paediatric cardiologist might still recommend key-hole closure of the PDA to prevent the risk of the PDA becoming infected, a dangerous condition known as infective endocarditis.

When a small PDA is found incidentally in an otherwise well child with no murmur then generally no treatment is recommended.
