Reversible cardio-pulmonary changes due to adeno-tonsilar hypertrophy

Association between adenoidal–nasopharyngeal ratio and right ventricular diastolic functions in children with adenoid hypertrophy causing upper airway obstruction

“…Those cardiac complications of adenoid hypertrophy are often reversible by surgical removal of the hypertrophied adenoids. Moreover, echocardiographic findings can improve postoperatively [1][2][3][4][5][6]. In our study, we confirmed those previous results.…”

“…Clinical consequences of this clinical condition are mouth breathing, obstructive sleep symptoms including loud snoring, behavioral problems, and failure to thrive. Those patients can also develop serious cardiopulmonary complications associated with hypercapnia and hypoxia [1][2][3][4][5][6]. Hypercapnia and hypoxia caused by obstructive hypoventilation result in respiratory acidosis, which in turn leads to pulmonary arterial vasoconstriction, increased right ventricular work and cardiac hypertrophy.…”

“…Echocardiography can be used to assess pulmonary pressures and right ventricular functions in those patients. Adenoid hypertrophy causing upper airway obstruction and cardiac complications can be effectively treated with adenoidectomy operation [1][2][3][4][5][6]. Determining the size of the hypertrophied adenoid is commonly needed before the operation.…”

Effect of Adenoidectomy and/or Tonsillectomy on Cardiac Functions in Children with Obstructive Sleep Apnea

“…Sustained pulmonary artery hypertension causes RV dilatation followed by eventual cardiac failure and cor pulmonale. Several authors have reported improvement in cor pulmonale following AT in children with OSAS [16,[34][35][36][37] . Similarly, we found high pulmonary arterial pressure values in children with adenotonsillary hypertrophy and OSAS.…”

Holter analyses in children with adenotonsillar hypertrophy

“…Following adenotonsillectomy in these children, it has been showed that the cardiac and pulmonary conditions could be reversed [14]. Hence, it becomes mandatory that the children undergoing tonsillectomy and adenoidectomy should be screened for cardiovascular complications and the investigations should include electrocardiography, echocardiography, pulse oximetry and chest radiography [15]. Cardiac complications of upper airway obstruction have been investigated by many scientists by using supplemental diagnostic modalities such as radionuclide ventriculography and echocardiography, chest radiography, electrocardiography [2,[15][16][17][18].…”
