    Assessment of pulmonary artery pressure and right ventricular function in children with adenotonsillar hypertrophy using different parameters
    (Elsevier Ireland Ltd, 2014) Çetin M.; Yilmaz M.; Özen S.; Bozan N.; Coşkun T.
    Objective: Our aim was comparison of preoperative and postoperative right ventricular functions of children with adenotonsillar hypertrophy (ATH) who have findings of upper airway obstruction, using new echocardiographic parameters. Methods: Forty-one children who have admitted to our hospital with symptoms suggestive of upper airway obstruction, whose history and physical examination findings suggest upper airway obstruction and who have undergone adenoidectomy/adenotonsillectomy and 40 healthy children, all of whom between 2 and 12 years of age, were included in the study. Patient group was evaluated by pulsed wave tissue Doppler echocardiography as well as with conventional echocardiography before the operation and 6 months after the operation. Results: Of 41 children in study group, 26 (63.4%) had adenotonsillectomy and 15 (36.6%) had adenoidectomy. Tricuspid annular plane systolic excursion (TAPSE) was significantly lower in preoperative group compared to control group (18.46. ±. 1.67, 19.77. ±. 1.62; p=0.000, respectively). Myocardial performance index (MPI) was significantly higher in preoperative group than postoperative and control group (0.40. ±. 0.07, 0.36. ±. 0.06, 0.35. ±. 0.07; p= 0.032, respectively). Tricuspid isovolumic acceleration (TIVA) was significantly lower in preoperative group than preoperative and control group (2.97. ±. 0.8, 3.43. ±. 0.7, 3.43. ±. 0.9; p= 0.020, respectively). Disappearance of this difference was found between postoperative and control groups (p= 0.984). Pulmonary acceleration time (PAcT) was found to be significantly lower in preoperative group compared to postoperative and control group (109.68. ±. 18.03, 118.93. ±. 17.46, 120.0. ±. 14.07; p= 0.010, respectively). Mean pulmonary artery pressure (mPAP) was significantly higher in preoperative group than control group (29.64. ±. 8.11, 24.95. ±. 6.33; p= 0.010, respectively). In postoperative group mPAP was found to be similar to control group (25.48. ±. 7.85, 24.95. ±. 6.33; p= 0.740, respectively). Conclusions: TAPSE, PAcT, MPI and TIVA are useful markers for evaluation of preoperative and postoperative ventricular function in children with ATH who have findings of upper airway obstruction. We think that using these practical and easy-to perform parameters may be relevant for evaluation and postoperative follow-up of patients with ATH who have findings of upper airway obstruction. Besides adenotonsillectomy is a beneficial treatment option for these patients. © 2014 Elsevier Ireland Ltd.

    Normal Values of Echocardiographic Parameters Indicating Right Ventricular Systolic Functions in 607 Healthy Children
    (Brieflands, 2023) Yılmaz M.; Çetin M.; Dundar P.E.; Coşkun Ş.
    Background: This study aimed to define the normal ranges of echocardiographic parameters that are used to evaluate right ventricular systolic functions. Methods: A total of 607 children within the age range of 0-18 years without any cardiac pathology or chronic disorders were included in the study. The study population was categorized into different age groups and underwent transthoracic echocardiog-raphy. In this study, tricuspid annular plane systolic excursion (TAPSE), tricuspid annular peak systolic velocity (TAPSV), and right ventricular myocardial performance index (RVMPI) values were measured. Results: There was no statistically significant difference between the mean TAPSE and TAPSV values of male and female subjects. The mean RVMPI was higher in females than in males. The study population was categorized into nine groups according to their age. The TAPSE, TAPSV, and RVMPI values were calculated for each group. Additionally, the 5th, 10th, 25th, 50th, 75th, 90th, and 95th percentiles, and ± 2 standard deviation (SD) and ± 3 SD values of TAPSE measurements were calculated for each age group. The study population was divided into eight groups according to their body surface area (BSA). Moreover, the 5th, 10th, 25th, 50th, 75th, 90th, and 95th percentiles of TAPSE measurements were calculated. There was a strong positive correlation between TAPSE and BSA. The TAPSE was also positively correlated with TAPSV but not with RVMPI. Conclusions: This study determined the normal values for TAPSV and RVMPI. It is important to have knowledge of the normal ranges of these parameters to recognize right ventricular dysfunction early in various cardiac disorders. © 2023, Author(s).
