The hallmark of the condition is a sunken appearance of the sternum. The most common form is a cup-shaped concavity, involving the lower end of the sternum; a broader concavity involving the upper costal cartilages is possible. The lower-most ribs may protrude ("flared ribs").<unk>  defects may be symmetric or asymmetric. People may also experience chest and back pain, which is usually of musculoskeletal origin. In mild cases, cardiorespiratory function is normal, although the heart can be displaced and/or rotated. In severe cases, the right atrium may be compressed, mitral valve prolapse may be present, and physical capability may be limited due to base lung capacity being decreased. Psychological symptoms manifest with feelings of embarrassment, social anxiety, shame, limited capacity for activities and communication, negativity, intolerance, frustration, and even depression.
