A surgical odyssey: Conquering a titanic tricuspid vegetation reaching into the superior vena cava - A case report.

INTRODUCTION

Right-sided infective endocarditis, particularly of the tricuspid valve, is rare and challenging to diagnose, often presenting with nonspecific symptoms, and associated with high mortality rates. This case underscores the complexities in managing such conditions and the importance of early diagnosis and multidisciplinary intervention.

CASE PRESENTATION: This case study details the medical history of a 34-year-old woman who had a background of intravenous drug abuse. She subsequently developed a fungal tricuspid valve endocarditis, leading to the formation of vegetation that extended into the superior vena cava. The mass measured 15 × 3 cm upon surgical removal.

DISCUSSION: Right-sided infective endocarditis is rare, comprising only 5-10 % of cases, with tricuspid valve endocarditis being even rarer. Damage to the endothelium facilitates bacterial attachment, especially in IV drug users, with Staphylococcus aureus being common. Fungal endocarditis is rare but deadly, with high mortality. Diagnosis relies on the modified Duke criteria, including microbiological and imaging evidence. Major complications affect both valvular and systemic areas. Treatment p1rimarily involves IV antibiotics, but surgery is needed for persistent infections or severe complications.

CONCLUSION

This case underscores the critical importance of early diagnosis and intervention in managing right-sided infective endocarditis, especially with a fungal pathology and in patients with complex medical histories.
