Summary

A Pediatric Chronic lung disease (CLD) is an abroad term that encompasses a heterogeneous group of different clinicopathological disorders that advance slowly over months or years. They can broadly be divided into two groups: those with a known cause and those without. Cystic fibrosis, broncho-pulmonary dysplasia or lung of prematurity, asthma, chronic gastro esophageal reflux/aspiration pneumonitis, and constrictive obliterative bronchiolitis, chronic infection, and hypersensitivity pneumonitis are all included in the first group. The second group is subdivided into primary pulmonary diseases (idiopathic interstitial pneumonia, persistent tachypnea of infancy associated with neuroendocrine cell hyperplasia, pulmonary lymphatic and vascular disorders, etc.) and systemic diseases with a pulmonary manifestation (e.g., Langerhans cell histio- cytosis, vasculities, and granulomatosis) Asthma is a chronic inflammatory disease of the airways which is related to airway obstruction, hyper responsiveness and characterized recurrent wheezing, coughing and breathlessness Asthma, recurrent hypoxemia, and hypercarbia, together with various mediators and cytokines released due to chronic inflammation, lead to pulmonary vasoconstriction Exaggerated respiratory efforts in asthmatic patients may increase intrathoracic pressure, which may increase right-ventricular (RV) afterload. Consequently, pulmonary hypertension may develop, which could then lead to RV hypertrophy and/or dilatation There are lacks of information's about right ventricular (RV) function in children with chronic lung diseases so in this study the RV systolic function will be evaluated. Systolic right ventricular (RV) function is an important predictor in the course of heart disease such as in pulmonary hypertension .The European Society of Cardiology and the American Society of Echocardiography recommend the use of tissue Doppler imaging for the evaluation of both diastolic and systolic functions .

Conditions

  • Right Ventricular Function

Interventions

OTHER

Echocardiographic examination

Standard 2D echocardiographic evaluation of right ventricle systolic function will be performed as follows: * Tricuspid annular peak systolic excursion (TAPSE) will be measured by placing M- mode cursor through tricuspid annulus and measuring the amount of longitudinal motion of the annulus at the peak systole in the longitudinal apical 4chamber view, TAPSE \<-2 Z Score is considered abnormal . * Tricuspid annular peak systolic velocity (TAPSV) by tissue Doppler \<-2 Z Score is considered abnormal. Through Tissue Doppler Imaging values of right ventricle will be obtained from the apical four -chamber view using a sample volume placed at the lateral corner of the tricuspid annulus. Peak systolic annular velocity (Ś).
