Chronic upper airway obstruction caused by adenotonsillar hypertrophy can result in various cardiac dysfunctions, but these can be improved through adenotonsillectomy. Cardiac screening in children with adenotonsillar hypertrophy can help identify and prevent cardiopulmonary complications.
Purpose Chronic upper airway obstruction caused by adenotonsillar hypertrophy is one of the major cause of morbidity in children. It can lead to Obstructive Sleep Apnoea Syndrome, Pulmonary Hypertension, Cor Pulmonale and right heart failure. The study aimed to evaluate and compare various parameters of cardiac function with the help of echocardiography preoperatively and postoperatively in children undergoing adenotonsillectomy. Methodology A prospective cohort study was conducted on 23 patients at an apex care institute, under the age group of 4-12 years, who were diagnosed with adenotonsillar hypertrophy. Preoperative symptom analysis and Echocardiographic examination were done. After the assessment, all patients underwent surgery in the form of adenotonsillectomy. Follow-up symptom analysis and echocardiographic examination was done after 3 months postoperatively. Results Significant improvement in the obstructive symptoms were noted in postoperative group as expected (p = < 0.001) and also in parameters such as mPAP (p = < 0.001), TAPSE (p = < 0.001), TAV (p = 0.001), Ejection fraction (p = 0.027) and RVMPI (p = 0.044) were improved in postoperative group. 4 patients had Grade 1 Right ventricular diastolic dysfunction, which disappeared in three patients postoperatively. Conclusion We have concluded that there can be subclinical cardiac dysfunctions which occurs as a result of chronic upper airway obstruction due to untreated adenotonsillar hypertrophy. Routine cardiac screening in children presenting with sleep disordered breathing associated with adenotonsillar hypertrophy may be helpful in identifying and preventing the development of cardiopulmonary complication. These changes can be reversed by performing adenotonsillectomy.
