Prevalence of congenital heart diseases in pediatric patients attending Pediatrics Department at Qena University hospital
Background: Congenital heart diseases (CHDs) may be defined as an anatomic malformation of the heart or
great vessels which occurs during intrauterine development, irrespective of the age at presentation.
Prevalence is often the starting point in the discussion of congenital cardiac lesions. It underlies the
estimation of disease burden, and helps us to begin to answer the question, “How big or important is this
problem?” It also opens a field of epidemiologic study aimed at defining causal or etiologic associations
with various genetic and environmental risk factors.
Objective: To detect the prevalence of CHD and the prevalence of its different types in pediatric patients
attending pediatrics department at Qena university hospital within six months.
Patients and method(s): This is a prospective, analytic study of patients rolled in pediatrics department of Qena
university hospital in outpatient cardiology clinic or inpatient word or pediatric intensive care unit or
neonatal department between August 2017 and February 2018.
Result(s): Between August 2017 to February 2018, 134 patients from 596 patients rolled in Pediatric department
by its different units were discovered to have CHDs. The average prevalence of CHDs in Pediatric department at
this period was 2.2 per 1,000. Relative frequency of congenital potentially cyanotic heart diseases was higher
than congenital acyanotic heart diseases and congenital cyanotic heart diseases with percentages of 16.1, 3.7%
and 2.7%, respectively.
Conclusion: The results of this systematic review give a general understanding of the CHDs epidemiology in
Pediatrics department. Family history of CHDs, low socioeconomic state and different syndromes were among
risk factors related to CHD in studies conducted in Pediatrics department. Identified risk factors are potentially
modifiable, emphasizing the importance of public health programs that are aimed at tackling such determinants.
Studies that explored the prognosis and burden of these diseases on the Qena society and healthcare services are
scarce and should be the focus for future research.
