Deformities of the thorax are usually classified as lordosis, kyphosis, kyphoscoliosis, pectus excavatum, and pectus carinatum. Of these, kyphosis, kyphoscoliosis, and pectus excavatum are the chief offenders. Lordosis usually presents no symptoms.

The first descriptions of early death in persons suffering from kyphoscoliosis did not incriminate the cardiovascular system, and it was not until the end of the last century that continental observers described heart failure as being the commonest cause.
