Hydatid Cyst Invading the Tricuspid Valve: Diagnostic Pitfalls and Surgical Lessons from a Near Fatal Case

Abstract

Background: Intracardiac hydatid cysts with valvular involvement are rare and diagnostically challenging.
Case Summary: A 68-year-old man presented with fever and chest pain. Echocardiography revealed a right-sided intracardiac mass with vegetative features, suggestive of infective endocarditis. Empiric antiparasitic and antibiotic therapy was initiated. Surgical exploration confirmed a hydatid cyst infiltrating the tricuspid annulus, along with multiple pulmonary cysts. The patient developed hemorrhagic shock during the first 24 hours and was reoperated with a successful outcome.
Discussion: This case illustrates the diagnostic ambiguity of intracardiac echinococcosis mimicking endocarditis and the limitations of echocardiography in differentiating complex masses. It underscores the importance of early multidisciplinary coordination and surgical planning in managing rare dual pathologies.
