An eleven-year review of pediatric echocardiogram reports in Kumasi, Ghana

Background Pediatric heart diseases (PHDs), comprising congenital heart diseases (CHDs) and acquired heart diseases (AHDs) are significant contributors to non-communicable diseases in children. CHDs alone occur in 0.8-1.0% live births globally. Data on echocardiogram diagnosed PHDs in Ghana however is lacking. We set out to describe the echocardiogram diagnosed prevalence of the various PHDs, their age profile and change in trends over an eleven-year period in children less than sixteen years seen in Kumasi. MethodsWe retrieved archived first echocardiogram scan reports from January 2010 through December 2020, and extracted the diagnosis, scan date and sex of the patients. PHDs were categorized into CHDs and AHDs and proportions of the top five reported respectively. Observed trends in proportion of types of PHDs and age at first diagnosis were computed. Data was collected using Microsoft® Excel and analyzed with R statistical software. ResultsPHDs were present in 49.9% (2474/4962) of the scans done with 51.5% (95%CI: 49.5-53.5) being males and 93.3% CHDs. The number of different diagnoses were 3344 as some of the patients had multiple diagnosis. Of these, the top five CHDs were Ventricular Septal Defect (699, 20.9%), Atrial Septal Defect (634, 19.0%), Patent Ductus Arteriosus (576, 17.2%), Tetralogy of Fallot (318, 9.5%) and Atrio-Ventricular Canal Defect (222, 6.6%). That for AHDs were Rheumatic Heart Disease (61, 1.8%), Dilated Cardiomyopathy (46, 1.4%), pericardial effusion (29, 0.9%), Hypertrophic Cardiomyopathy (26, 0.9%) and Infective Endocarditis (14, 0.4%). Proportion of various PHDs stayed constant over the years (p=0.129). The median (IQR) age in months for acyanotic CHDs (6, 1.5-18), cyanotic CHDs (15.0, 4.0-36.0) and AHDs (72.0, 19.0-120) were significantly different (p<0.001). Age at diagnosis reduced by 0.46 months per year, (95%CI: 0.01 to 0.92, p=0.046) over the 11-year period. ConclusionPrevalence of CHDs and AHD are similar to other reports worldwide and has remained largely unchanged over the 11-year period. Age at first diagnosis however is reducing for all PHDs.
