Pectus excavatum (PE), also known as “sunken chest” or “funnel chest,” is a birth defect characterized by a sunken sternum, or breastbone. It is fairly common, affecting one in every 1,000 kids. For every girl affected by PE, four boys will suffer with it. Shortness of breath with exertion and chest pain are the two most common problems caused by the deformity and can be debilitating. Fortunately, the minimally invasive “Nuss” procedure alleviates these problems with minimal scarring, giving patients more self-confidence and an improved quality of life.
