Current controversies in infective endocarditis

Area of Science:

• Cardiology
• Infectious Diseases
• Medical Microbiology

Background:

• Infective endocarditis is a life-threatening infection of the heart's inner lining.
• The disease exhibits evolving microbiology and patient demographics, complicating management.
• Current clinical practice lacks extensive evidence, leading to numerous controversies.

Purpose of the Study:

• To review current uncertainties in the prevention, diagnosis, and surgical management of infective endocarditis.
• To explore strategies for reducing healthcare-associated bacteraemia and the role of antibiotic prophylaxis.
• To discuss the utility of multimodality imaging in diagnosis and challenges in cardiac device infections.

Main Methods:

• Literature review of key areas of uncertainty in infective endocarditis.
• Analysis of evidence regarding antibiotic prophylaxis and healthcare-associated bacteraemia prevention.
• Evaluation of diagnostic imaging modalities and surgical intervention timing.

Main Results:

• Significant controversies persist regarding antibiotic prophylaxis and prevention of healthcare-associated bacteraemia.
• Multimodality imaging offers potential advancements in diagnosing infective endocarditis.
• Optimal surgical timing and management of cardiac device infections remain challenging.

Conclusions:

• Addressing uncertainties in prevention, diagnosis, and surgical intervention is crucial for improving infective endocarditis outcomes.
• Further research is needed to establish evidence-based guidelines for managing this complex disease.
• The increasing incidence of cardiac device infections necessitates specific management strategies.
