A forty-year review of bacterial endocarditis in infancy and childhood
Insights
Bacterial endocarditis (BE) survival has improved in young patients, with congenital heart disease posing the highest risk. Surgical correction of congenital heart disease may be the best prevention strategy.
Area of Science:
- Pediatric Cardiology
- Infectious Diseases
- Cardiovascular Surgery
Background:
- Bacterial endocarditis (BE) is a serious infection affecting heart valves.
- Congenital heart disease (CHD) and rheumatic heart disease (RHD) are significant risk factors for BE.
- Understanding trends in BE is crucial for pediatric patient management.
Purpose of the Study:
- To analyze trends in bacterial endocarditis (BE) in patients under 25 years of age.
- To identify specific congenital heart conditions associated with increased BE risk.
- To evaluate survival rates and outcomes following BE in relation to underlying heart conditions.
Main Methods:
- Retrospective review of 149 BE episodes in 141 pediatric patients (1933-1972).
- Analysis of patient demographics, underlying cardiac conditions, pathogens, and outcomes.
- Comparison of outcomes based on specific congenital heart defects.
Main Results:
- Increasing survival rates for bacterial endocarditis (BE) observed over the study period.
- Tetralogy of Fallot, small ventricular septal defect, and aortic stenosis identified as high-risk congenital heart conditions for BE.
- Patients with ventricular septal defect and tetralogy of Fallot showed better outcomes post-BE compared to those with aortic outflow lesions.
- Alpha Streptococcus and Staphylococcus aureus were the most common pathogens identified.
Conclusions:
- Surgical correction of congenital heart disease may serve as a primary preventive measure against BE.
- Specific congenital heart defects confer different risks and prognoses for bacterial endocarditis.
- Long-term trends indicate improved management and outcomes for pediatric bacterial endocarditis.
Abstract:
A retrospective review of 149 episodes of bacterial endocarditis (BE) in 141 patients under 25 years of age, at The Children's Hospital Medical Center from 1933 through June of 1972, demonstrates increasing survival and a distinct change in the frequency of underlying congenital heart disease and rheumatic heart disease (RHD). Certain forms of congenital heart disease such as tetralogy of Fallot, small ventricular septal defect, and aortic stenosis are at particular risk for BE. Following BE, patients with ventricular septal defect and tetralogy of Fallot have less morbidity and higher survival rates than children with aortic outflow lesions. over the entire time period, alpha Streptococcus is the most common pathogen and Staphylococcus aureus, second most frequent organism. Surgical correction in patients with congenital heart disease may offer the best form of prevention.
