Paediatric cardiac diseases in a tertiary facility in Southwest Nigeria: a five-year retrospective audit of echocardiography studies.

BACKGROUND

Echocardiography has become a crucial diagnostic tool for assessing heart diseases in children within low- and middle-income countries, where the burden of heart diseases remains substantial.

OBJECTIVES

This study aimed to audit echocardiography (echo) reports by reviewing the trends in echocardiography, indications for echocardiography, and the frequency and pattern of paediatric heart diseases seen at the Paediatric Cardiology Unit of the Obafemi Awolowo University Teaching Hospitals Complex, Ile-Ife, over a five-year period.

METHODS

A total of 1,155 echocardiography reports were reviewed using a structured proforma to extract relevant data. Statistical analyses were conducted using IBM SPSS version 25.

RESULTS

Male participants constituted 52.1% of the study population. Ages ranged from 9 hours to 18 years, with a mean ± SD of 3.24 ± 4.46 years. The most frequent indication for echocardiography was fast breathing (38.27%). Approximately 31.86% of the echocardiograms were normal. CHD accounted for 63.55% of diagnoses, with 67.17% classified as acyanotic CHD and 32.83% as cyanotic CHD. Ventricular septal defect (VSD, 15.26%) and tetralogy of Fallot (TOF, 14.99%) were the most common CHDs. Acquired heart diseases were found in 4.59% of cases, with rheumatic heart disease being the most prevalent within this group (35.85%).

CONCLUSION

CHDs remain the predominant paediatric heart diseases, occurring nearly 14 times more frequently than acquired heart diseases. Ventricular septal defect and tetralogy of Fallot were the most common acyanotic and cyanotic CHDs, respectively. Among the acquired heart diseases, rheumatic heart disease was the leading diagnosis.
