ObjectiveComparison of left ventricular functions in preoperative and postoperative periods of children with adenotonsillar hypertrophy (ATH) who have findings of upper airway obstruction (UAO), using echocardiographic parameters.MethodsThirty children who were diagnosed with UAO due to ATH, and who have undergone adenoidectomy/adenotonsillectomy and 30 healthy children, between 2 and 11 years of age, were included in the study. Patient group was evaluated by the pulsed wave tissue Doppler echocardiography, as well as with conventional echocardiography, before and 6 months after the operation.ResultsOf 30 children in study group, 18 (60%) had adenotonsillectomy and 12 (40%) had adenoidectomy. The differences between groups regarding myocardial performance index (MPI) was not statistically significant (p = 0.847). There was not any statistically significant difference between groups in terms of mitral isovolemic acceleration (MIVA) (2.28 ± 0.67, 2.24 ± 0.55, 2.23 ± 0.49; p = 0.943, respectively). Interventricular septum diameter (IVSD) was significantly higher in preoperative group than postoperative and control groups (3.68 ± 0.52, 3.50 ± 0.40, 3.38 ± 0.60; p = 0.028, respectively). Pulmonary acceleration time (PAcT) was found to be significantly lower in preoperative group compared to postoperative and control groups (107.64 ± 16.60, 119.52 ± 15.95, 120.47 ± 16.19; p = 0.004, respectively). Mean pulmonary arterial pressure (mPAP) was significantly higher in preoperative group than postoperative and control groups (30.58 ± 8.11, 25.23 ± 9.07, 25.00 ± 6.52; p = 0.002, respectively). In postoperative group mPAP was found to be similar to the control group.ConclusionsClinical or subclinical left ventricle (LV) dysfunction in children with ATH who have findings of UAO was not determined while mean pulmonary arterial pressure was significantly higher compared with the control cases. Besides early adenotonsillectomy is a beneficial treatment option for these patients.
