Background: Cardiac complications in children with infectious diseases may not show obvious symptoms but can affect prognosis. Echocardiography helps identify structural and functional heart problems, supporting both immediate care and long-term management.This study aimed to assess echocardiographic findings in pediatric patients admitted with infectious diseases and to describe the types and prevalence of cardiac involvement.Method: We conducted a randomized retrospective review of 34 pediatric patients admitted to an infectious disease unit in 2024 who underwent echocardiography. Every 5th patient from the database was included. Clinical data, imaging results, and discharge diagnoses were analyzed. Echocardiographic findings were grouped as structural defects, valvular disorders, or hemodynamic abnormalities.Results: Seventeen patients (50%) had normal echocardiograms. Among the remaining cases, mitral valve prolapse and pericardial effusion were each seen in 3 patients (8.8%). Atrial septal defect (ASD) was found in 1 patient (2.9%), isolated ventricular septal defect (VSD) in 2 patients (5.9%), and one patient (2.9%) had VSD combined with coarctation of the aorta. Patent foramen ovale (PFO) without hemodynamic significance was present in 4 patients (11.8%).More complex findings included coarctation of the lower aorta with vena cava collapse and increased transmitral flow in 2 patients (5.9%), and aortic stenosis with a bicuspid aortic valve and ventricular dilatation in 1 case (2.9%).Conclusion: While half of the children had normal echocardiograms, a notable proportion showed structural or functional heart abnormalities, ranging from mild lesions like PFO or mitral valve prolapse to complex defects such as aortic coarctation and bicuspid aortic valve with stenosis.These findings highlight the value of routine echocardiographic evaluation in pediatric infectious disease patients, even when cardiac symptoms are absent, to enable timely intervention and improve long-term outcomes.
