The effect of adenotonsillectomy on right ventricle function and pulmonary artery pressure in children with adenotonsillar hypertrophy

Objectives: Adenotonsillar hypertrophy (ATH) is the most common cause of upper airway obstruction in children. Severe upper airway obstruction may have an effect on chronic alveolar hypoventilation, which consequently may lead to right ventricle (RV) dysfunction induced by hypoxemic pulmonary vasoconstriction. The investigators aimed to study RV function and mean pulmonary artery pressure (mPAP) in patients with ATH who were undergoing adenotonsillectomy by using tissue Doppler echocardiography (TDE)
