Tricuspid Valve Infective Endocarditis with Severe Tricuspid Regurgitation

Area of Science:

• Cardiology
• Infectious Diseases
• Public Health

Background:

• Tricuspid valve infective endocarditis (TVIE) is a severe complication often linked to intravenous drug use (IVDU).
• TVIE can lead to critical issues like severe tricuspid regurgitation, septic embolization, and vegetation growth.
• Managing TVIE in IVDU patients requires specialized, multidisciplinary care strategies.

Purpose of the Study:

• To highlight the complexities in treating TVIE in an IVDU patient.
• To emphasize the critical need for multidisciplinary care and integrated social interventions.
• To discuss challenges related to treatment adherence and continuity of care in this population.

Main Methods:

• A case report of a male patient in his early 40s with a history of IVDU and hepatitis C.
• Clinical presentation included chest pain, cough, fevers, and groin swelling.
• Diagnostic workup involved blood cultures and echocardiography, revealing methicillin-sensitive Staphylococcus aureus bacteremia and a large tricuspid valve vegetation with severe regurgitation.

Main Results:

• Despite initial antibiotic treatment, the patient showed poor adherence and left against medical advice.
• The patient returned with worsening symptoms, persistent bacteremia, and vegetation growth, indicating a need for surgery.
• The patient ultimately refused surgery due to concerns about compliance, surgical risks, and ongoing substance use, leading to loss to follow-up.

Conclusions:

• Managing TVIE in IVDU patients is challenging due to issues with treatment adherence and continuity of care.
• Early multidisciplinary intervention, including addiction support and supervised therapy, is crucial.
• Integrating medical and social interventions is vital for improving outcomes and reducing recurrence in this high-risk group.
