Abstract

PURPOSE
This study aimed to evaluate and compare the characteristics of infective endocarditis (IE) between children and adults with congenital heart disease (CHD) at a single tertiary care center.
METHODS
In this retrospective medical record review, we extracted the demographic characteristics, diagnostic variables, and outcomes of patients diagnosed with IE and CHD between 2000 and 2016.
RESULTS
We identified a total of 14 pediatric patients (nine male; median age at diagnosis, 3 years). Of the 14 patients, six had a history of previous open heart surgery, while four had undergone tetralogy of Fallot repair, with transannular patch or Rastelli procedure. Among the 10 children with positive blood cultures, the most common isolated organism was Staphylococcus spp. (8/10, 80%). Eleven adult patients had IE and CHD. Among the adult patients, only four were diagnosed with CHD before IE, and ventricular septal defect was the most common CHD. The most common isolated organism was Streptococcus spp. (6/11, 55%). Compared with adult patients, pediatric patients had a higher incidence of previously diagnosed CHD (P=0.001), with Staphylococcus spp. as the causative organism (P =0.027). The median duration between the onset of symptoms and diagnosis of IE was 9 days in children and 42 days in adults (P=0.012).
CONCLUSIONS
Significant differences with regard to the diagnosis and progress of IE were observed between children and adults. Ageadjusted and systematic reassessment may be necessary for the diagnosis and management of IE.
