Children with grade III or IV of adenotonsillar hypertrophy especially of a longer duration, may show cardiovascular changes due to mouth breathing. These changes can be detected on doppler echocardiocardiography which can be used as a screening tool. Fifty paediatric patients of grade 3 and 4 adenotonsillar hypertrophy underwent adenotonsillar resection after a pre-operative work up which included doppler echocardiography to measure pulmonary artery pressures. A post-operative doppler echocardiography was done after three months. 11 children (22%) showed deranged pulmonary artery pressure values with increased mean pulmonary artery pressure (MPAP) and pulmonary artery systolic pressure (PSAP) on preoperative doppler echocardiography, and 2 out of these 11 children had Pulmonary Artery Hypertension. A significant (p < 0.001) improvement was noted in pulmonary artery pressure values (MPAP and PSAP returned to normal) after adenotonsillectomy in 3-month postoperative echocardiography. Also, a statistically significant correlation was obtained between chronicity of symptoms and raised pulmonary artery pressures. Our study concluded that these children with chronic untreated upper airway obstructive symptoms get predisposed to potential cardiac complications. And these grave consequences can be easily prevented by a timely intervention.
