Echocardiography in pediatric infective endocarditis

Area of Science:

• Pediatric Cardiology
• Infectious Diseases
• Diagnostic Imaging

Background:

• Endocarditis diagnosis in children presents unique challenges.
• Transesophageal echocardiography (TEE) shows high sensitivity in adults, but pediatric data are limited.
• Transthoracic echocardiography (TTE) is a less invasive alternative.

Purpose of the Study:

• To evaluate the diagnostic sensitivity of TTE for endocarditis in pediatric patients.
• To compare TTE sensitivity between pediatric-sized and adult-sized subjects.
• To determine if TTE is sufficient for endocarditis detection in children.

Main Methods:

• Retrospective analysis of 39 pediatric endocarditis cases.
• Subjects categorized into pediatric-sized (<60 kg) and adult-sized (≥60 kg) groups.
• Comparison of TTE sensitivity between the two groups.

Main Results:

• TTE demonstrated 97% sensitivity in pediatric-sized subjects (<60 kg).
• TTE sensitivity was lower at 70% in adult-sized subjects (≥60 kg) (P < 0.05).
• A statistically significant difference in TTE sensitivity was observed based on size.

Conclusions:

• Transthoracic echocardiography is highly sensitive and generally sufficient for detecting endocarditis in children weighing less than 60 kg.
• TEE may be considered for larger pediatric patients or when TTE is inconclusive.
• TTE serves as a valuable primary diagnostic tool for endocarditis in younger/smaller children.
