Materials and methods: Ninety-one children (26 female 65 male) who were diagnosed as ATH in the pediatric outpatient clinic and twenty-three completely healthy, age-sex matched children (10 female 13 male) were included in the study. All patients underwent a complete twodimensional transthoracic echocardiographic and Doppler study. Results: Mean mitral E, A and deceleration time were significantly longer in ATH group. Also chamber areas and volumes were bigger. Pulmonary and mitral regurgitation were statistically more frequent in ATH group. Adenotonsillar grade was positively related with mean pulmonary arterial pressure (r: 0.44 p: <0.001). Mitral valve thickness was strongly correlated with tonsillar hypertrophy grade (r: 0.73; p.<0.001). Conclusions: ATH may lead to mild diastolic dysfunction and chamber dilatation. Mitral valve thickness was strongly correlated with adenotonsillar grade. © 2011 Düzce Medical Journal.eninfo:eu-repo/semantics/closedAccessAdenotonsillar hypertrophy; Apnea; Cardiac function; Rheumatic heart disease; Snoring; Subclinical carditisArticle1325155Q4
