خلاصه: Background
The goal of this study was to evaluate the effects of adenotonsillectomy on heart function based on echocardiography indices in children with primary snoring (PS) and mild obstructive sleep apnea due to adenotonsillar hypertrophy (ATH).
Methods
55 children (aged 7 to 11 years old) with PS and ATH who were a candidate for adenotonsillectomy from August 2018 to June 2019 evaluated. A history of Upper Respiratory Tract Obstruction was obtained, clinical examination was performed and the cases suspicious for moderate to severe degrees of Obstructive Sleep Apnea Syndrome were excluded. Echocardiography was performed one week before and 3–6 months after surgery. All data were analyzed by SPSS version 19 and P-value<0.05 was considered significant.
Results
From 55 enrolled cases, 42 [30 boys (71.5%) and 12 girls (28.5%)] completed the study course. Tricuspid Annular Plane Systolic Excursion (TAPSE), Ejection Fraction (EF), Right Ventricular Peak Systolic Myocardial Velocity (RVSM), Right Ventricular Fractional Area Change (RVFAC) were increased significantly and Isovolumic Contraction Time (IVCT) index was decreased significantly after surgery (P-value<0.05). The difference of indices between the two sexes was not significant after surgery (P-value>0.05).
Conclusion
Adenotonsillectomy can improve cardiac function indices in patients with PS due to ATH especially in terms of right ventricle (RV) function and reduction in pulmonary artery pressure. So, although “subclinical”, it is better to be considered PS not just as annoying noise for roommates before significant clinical cardiac problems happen.
