Abstract
Background
Our aim was to compare pediatric infective endocarditis (IE) with the clinical profile and outcomes of IE in adults.
Methods
Prospective multicenter registry in 31 Spanish hospitals including all patients with a diagnosis of IE from 2008 to 2020.
Results
A total of 5590 patients were included, 49 were <18 years (0.1%). Congenital heart disease (CHD) was present in 31 children and adolescents (63.2%). Right-sided location was more common in children/adolescents than in adults (46.9% vs. 6.3%, P < 0.001). Pediatric pulmonary IE was more frequent in patients with CHD (48.4%) than in those without (5.6%), P = 0.004. Staphylococcus aureus etiology tended to be more common in pediatric patients (32.7%) than in adults (22.3%), P = 0.082. Heart failure was less common in pediatric patients than in adults, due to the lower rate of heart failure in children/adolescents with CHD (9.6%) with respect to those without CHD (44.4%), P = 0.005. Inhospital mortality was high in both children, and adolescents and adults (16.3% vs. 25.9%; P = 0.126).
Conclusions
Most IE cases in children and adolescents are seen in patients with CHD that have a more common right-sided location and a lower prevalence of heart failure than patients without CHD. IE in children and adolescents without CHD has a more similar profile to IE in adults.
Impact
-
Infective endocarditis (IE) in children and adolescents is often seen in patients with congenital heart disease (CHD).
-
Right-sided location is the most common in patients with CHD and heart failure is less common as a complication compared with patients without CHD.
-
Infective endocarditis (IE) in children/adolescents without CHD has a more similar profile to IE in adults.
-
In children/adolescents without CHD, locations were similar to adults, including a predominance of left-sided IE.
-
Acute heart failure was the most frequent complication, seen mainly in adults, and in children/adolescents without CHD.
