Evidence of cardiac dysfunction in patients with pectus excavatum (PE) remains controversial. A growing number of studies report increased exercise tolerance following surgery. Nevertheless, many consider the correction of PE a cosmetic intervention, with post-operative changes ascribed to the concurrent growth of the young patient population. No studies have investigated non-invasively the immediate cardiac changes following relief of the deformity. The aim of this study was to assess cardiac function before and during temporary sternal elevation using the non-invasive vacuum bell (VB) device on young adults with PE.
