Pectus Carinatum - Symptoms

Symptoms

People with pectus carinatum usually develop normal hearts and lungs, but the deformity may prevent these from functioning optimally. In moderate to severe cases of pectus carinatum, the chest wall is rigidly held in an outward position. Thus, respirations are inefficient and the individual needs to use the diaphragm and accessory muscles for respiration, rather than normal chest muscles, during strenuous exercise. This negatively affects gas exchange and causes a decrease in stamina. Children with pectus deformities often tire sooner than their peers, due to shortness of breath and fatigue. Commonly concurrent is mild to moderate asthma.

Some children with pectus carinatum also have scoliosis (curvature of the spine). Some have mitral valve prolapse, a condition in which the heart mitral valve functions abnormally. Connective tissue disorders involving structural abnormalities of the major blood vessels and heart valves are also seen. Although rarely seen, some children have other connective tissue disorders, including arthritis, visual impairment and healing impairment.

Apart from the possible physiologic consequences, pectus deformities can have a significant psychologic impact. Some people, especially those with milder cases, live happily with pectus carinatum. For others, though, the shape of the chest can damage their self-image and confidence, possibly disrupting social connections and causing them to feel uncomfortable throughout adolescence and adulthood. As the child grows older, especially if male, bodybuilding techniques may be useful for balancing visual impact.
