Cardiac dysfunction after operative correction of a thoracic hyperkyphosis in a patient with a severe pectus excavatum

This case study demonstrates that surgical correction of thoracic hyperkyphosis in the presence of pectus excavatum can lead to the clinical manifestation of previously asymptomatic cardiac issues. Due to the biomechanical interaction between the spine, ribs, and sternum, deformities in this region can influence each other. We recommend checking preoperatively whether pectus excavatum is present and then correcting it surgically as a priority to avoid cardiac complications.
