Effects of severe scoliosis on cardiac structure and function in resting patients: a retrospective study

Severe thoracic scoliosis significantly affects cardiac structure and function at rest, primarily impacting left ventricular dimensions and cardiac index. Age and gender influence specific cardiac structural parameters but have a limited impact on cardiac function. Preoperative assessments should prioritize LVDd and CI for a thorough evaluation of cardiac health in these patients. The direction of the primary thoracic curve does not significantly influence cardiac structure or function. The severity of the spinal deformity, rather than the curvature direction, is the main determinant of its impact on cardiac health.
