Association between adenoidal-nasopharyngeal ratio and right ventricular diastolic functions in children with adenoid hypertrophy causing upper airway obstruction

Abstract

Objective: Adenoid hypertrophy causing upper airway obstruction can cause cardiovascular complications, including pulmonary hypertension and right heart failure in children. Adenoidal-nasopharyngeal ratio (ANR) is a practical, non-invasive and reliable method to evaluate adenoid enlargement. Our aim was to evaluate a possible association between ANR and echocardiographic parameters of right ventricle.
