Domany KA, Huang G, Schuler CL, et al. - Given that alterations in left ventricular structure as well as function have been earlier reported in children suffering from obstructive sleep apnea (OSA), so, researchers investigated whether these structural as well as functional cardiac alterations are reversible post-treatment of OSA with adenotonsillectomy. This analysis involved children aged 5 to 13 years with OSA and matched healthy controls. Adenotonsillectomy was performed within 1 month post-diagnosis. Findings revealed the presence of impaired left ventricular relaxation during diastole, suggesting early stage diastolic dysfunction, in children with OSA. A significant improvement of diastolic function was achieved with adenotonsillectomy for OSA. Experts found that left ventricular remodeling did not alter with OSA improvement.
