Background: Congenital heart diseases are the second group of congenital anomalies in infants. These disorders are a major cause of death in the first year of a child's life. Early detection helps to treat these diseases better. In this study cardiology consultations of hospitalized infants in the neonatal intensive care unit were evaluated.
Methods: In this cross-sectional study, two hundred and fifty pediatric cardiology consultations conducted in Shahid Beheshti Hospital in the year 2012 were reviewed. Information such as the cause of consulting, delivery type, age of parents, relative couples, family history of congenital heart disease, maternal medications, maternal background diseases, the final diagnosis, and prognosis follow-up of the patients were recorded in a designed questionnaire. Finally, the data were entered into the SPSS software, version 16 (IBM SPSS, Armonk, NY, USA) and analyzed using descriptive statistics and chi-square test. P-value of less than 0.05 was considered significant.
Results: The mean age of the consulted neonates was 4.845±5.14 days with a gestational age of 33.933±3.65 weeks. Male sex and cesarean section were the most frequent. Fifty-six percent of consulted infants were male. The present study revealed that prematurity (76%), murmurs (30.8%), respiratory distress syndrome (14.4%) and cyanosis (13.2%) were the most common causes of the cardiac consultation seeking among infants. Seventy-six percent of infants were consulted due to prematurity. Eighty-four percent of infants had a normal conditions. Septal defects (ventricular or atrial septal defect) and patent ductus arteriosus were the most common disease diagnosed with the prevalence of 27.5 and 17.5%, respectively. There was a significant relationship between preterm labor and congenital heart disease (P<0.001). Additionally, prematurity associated with respiratory distress syndrome and using assisted reproductive techniques.
Conclusion: The higher prevalence of congenital heart disease in the present study, compared with other studies, reflects the fact that cardiology consultation based on clinical suspicion leads to the more identification of congenital heart disease that means the right referral of newborns for consultation was accompanied with a higher incidence of heart failure.
