The study examined 27 children with ATH who had a mean age of 8 ¡À 2 years. The subjects were comprised 17 (63 % ) males and 10 (37 % ) females. Hypertrophy of the tonsils was graded according to the Brodsky scale. Children having either grade 3 or 4 hypertrophied adenotonsils were recruited for the study. Adenotonsillectomy was performed on all subjects in the study group and echocardiographic examination was repeated 3 months postoperatively.
Tricuspid Em significantly increased after adenotonsillectomy (17.7 ¡À 3.6 vs. 19.1 ¡À 5.5, p = 0.04). The RV myocardial performance index (MPI) and mPAP significantly decreased after adenotonsillectomy (RV MPI: 0.57 ¡À 0.13 vs. 0.40 ¡À 0.12, p < 0.001 and mPAP (mm Hg): 31 ¡À 9 vs. 25 ¡À 7, p = 0.001).
The results of this study, evaluated with the results of previous studies, demonstrated that adenotonsillectomy improved RV performance and reduced mPAP in children with ATH.
