Endocarditis in Adults with Congenital Heart Disease

Area of Science:

• Cardiology
• Infectious Diseases
• Congenital Heart Disease

Background:

• Infective endocarditis (IE) is a leading cause of death in patients with congenital heart disease (CHD).
• Adults with CHD have an elevated lifetime risk of IE due to complex cardiac anatomy, prosthetic materials, and interventions.
• IE in CHD patients presents unique epidemiological, microbiological, and clinical challenges compared to the general population.

Purpose of the Study:

• To review the distinct aspects of IE in patients with CHD.
• To highlight diagnostic challenges and management strategies specific to this population.
• To emphasize the importance of preventive measures for IE in CHD patients.

Main Methods:

• Review of current literature on IE in CHD.
• Analysis of epidemiological, microbiological, and clinical data.
• Discussion of diagnostic modalities and treatment approaches.

Main Results:

• Streptococcal species and Staphylococcus aureus are the most common pathogens.
• Diagnosis is complicated by complex anatomy and prosthetic material, necessitating high clinical suspicion and advanced imaging.
• Prolonged antimicrobial therapy and frequent surgical interventions are often required.
• Complications at presentation are more common in CHD patients.

Conclusions:

• IE management in CHD requires a multidisciplinary approach, considering unique patient factors.
• Multimodality imaging and a high index of suspicion are vital for accurate diagnosis.
• Preventive strategies, including antibiotic prophylaxis and hygiene, are paramount for reducing IE incidence in this vulnerable group.
