Pectus excavatum is an abnormal inward curve to the breastbone. It may be visible at birth. Growth through adolescence can make the indentation of the chest more apparent. It may continue until it has created a bowl-shape dent in the center of the chest.
Severe forms can create extra pressure on the heart and lungs. This can lead to more serious health problems like shortness of breath and limited physical activities.
The exact cause of pectus excavatum is not known. Some theories include:
Pectus excavatum may also be caused by conditions that affect connective tissue or chest structure, such as:
Risk factors include:
Complications from pectus excavatum tend to increase with age due to bone growth and a decrease in the flexibility of the bones.
Pectus excavatum is characterized by an indentation in the front of the chest wall. It may be mild or deep enough to form a bowl shape.
If the indentation is severe enough to affect the heart or lungs you may also have:
A person with this condition may not have any symptoms during childhood. But as the person grows into an adolescent, he may have symptoms because of of a more pronounced indentation in the chest wall.
You will be asked about your symptoms and medical history. A physical exam will be done.
Your doctor will often be able to diagnose pectus excavatum after a physical exam.
Additional tests may be done to find out if your heart or lungs are affected. These tests may include:
Talk with your doctor about the best treatment plan for you. Options include:
Surgery may be considered for those who:
The ideal age for this type of surgery is 7-14 years. But surgery can also be successful in adults, as well. There are 2 main surgical options:
Open Surgery (Ravitch Procedure)
This surgery involves incisions in the front of the chest. The surgeon will be able to see your breastbone. Some cartilage will be removed from your breastbone and nearby ribs. The surgeon will place the breastbone in its proper position. A metal strut and mesh will be used to support the new position. The metal strut may come out in 6-12 months.
Minimally Invasive Surgery (Nuss Procedure)
Small incisions are made on either side of the chest. The surgeon will place a metal bar through the incisions and secure it under the breastbone. This bar will push the breastbone into a better position. This bar will remain in the chest for 2-3 years. This will allow the chest time to remodel itself.
Your doctor or physical therapist may recommend exercises or a rehabilitation program. Certain exercises and postural positions may decrease the appearance of mild pectus excavatum.
There is no known way to prevent this condition.
