Funnel chest

Authoring team

Patients with severe pectus excavatum show cardiorespiratory problems and increased susceptibility to infection.

Patients with a mild to moderate funnel chest tend to be asymptomatic at rest. However, studies conducted by the National Heart, Lung and Blood Institute conclude that these patients:

have cardiac and respiratory insufficiency

have significantly lower working capacity in the sitting position than the supine position

demonstrate a lower increase in stroke volume when going from rest to exercise in the sitting position compared to normal patients - believed to result from poorer ventricular filling

show marked improvements in cardiac output during intense upright exercise following corrective surgery
