title: The Effect of Tonsillectomy and Adenoidectomy on Right Ventricle Function and Pulmonary Artery Pressure by Using Doppler Echocardiography in Children.
abstract: OBJECTIVE
  The purpose of the present study is to emphasize the efficacy of the myocardial performance index and tricuspid annular plane systolic excursion (TAPSE) in the determination of impaired cardiac functions and recovery period following the treatment in children with adenoid and/or tonsillar hypertrophy.
  
  
  METHODS
  Fifty-three healthy children after routine laboratory, imaging and clinical examinations, with adenoid and/or tonsillar hypertrophy were evaluated before and 3 months after adenotonsillectomy for cardiac functions using M mode and Doppler echocardiography.
  
  
  RESULTS
  The mean age of cases was 6.4±3.0 years, 34 (65%) were male, and 19 (35%) were female. Pulmonary hypertension was observed to be mild in 3 patients and moderate in 1 patient preoperatively. When the preoperative and postoperative echocardiographic measurements of the patients were compared, the tricuspid valve E wave velocity, the E/A ratio (E, early diastolic flow rate; A, late diastolic flow rate), and the TAPSE values were determined to be significantly higher postoperatively (P<0.05). The tricuspid valve deceleration time, the isovolumetric relaxation time and the systolic pulmonary artery pressure were found to be significantly lower compared to the preoperative values (P<0.05).
  
  
  CONCLUSIONS
  Adenoidectomy and/or tonsillectomy may prevent cardiac dysfunctions that can develop in the later periods due to adenoid and/or tonsil hypertrophy in children, before the appearance of the clinical findings of cardiac failure.
