While it is generally asymptomatic, cardiorespiratory symptoms in the form of palpitations, dyspnea, and wheezing are not uncommon, may be accentuated during exercise and disappear after surgery. Bronchial and pulmonary symptoms of asthma and chronic bronchitis occur in 16.4% of the patients. Because the physical deformity can evoke ridicule from their peers, these patients are often introverted with low self-esteem and tend to avoid appearing in public venues or engaging in sports in which they may have to remove their shirts.

Moderate cases cause no difficulties and require no treatment; in severe cases the deformity may interfere with lung and heart action, causing dyspnea on exercise and increased susceptibility to respiratory infections. Serious malformations can usually be corrected by surgery. Called also pigeon breast or chest and chicken breast. pectus excava´tum a congenital malformation of the chest wall characterized by a funnel-shaped depression with its apex over the lower end of the sternum; it is caused by shortening of the central portion of the diaphragm, which pulls the sternum backward during inhalation, and by the growth of ribs. Except in mild cases, it decreases the ability of the child to engage in sustained exercise. It also delays recovery from coughs and colds, reduces the ability to eat a full meal (so that most patients are underweight), and often produces a functional heart murmur. Noisy breathing may occur during sleep. A child may develop an emotional problem because of embarrassment over the deformity. It can be satisfactorily corrected by surgery. Called also funnel breast or chest and koilosternia.
