Coronary Artery Fistula | Symptoms & Causes
What are the symptoms of coronary artery fistula?

- Chest pain
- Shortness of breath
- Slow growth

How is coronary artery fistula treated?
In most cases, a small fistula that's not causing symptoms won't need treatment. Some small fistulas eventually close on their own, but even if it doesn’t close, it may not cause symptoms and won’t need to be treated.
Children with a larger fistula may need surgery to close the connection with stiches or a patch. In some cases, the doctor may use a special wire coil to plug the opening instead of surgery. The coil is inserted into the heart using a long, thin tube called a catheter.
What is the long-term outlook for coronary artery fistula?
Most children with this condition do well and have a normal lifespan. Some children may need more than one surgery.
