Challenging Case of Marantic Tricuspid Endocarditis Treated With Percutaneous Vegetation Debulking

Marantic endocarditis is a rare entity often diagnosed in the setting of advanced malignant disease. We present the case of a 66-year-old man with stage IVb non-small cell lung cancer, with large tricuspid and small aortic valve vegetations. A multidisciplinary team determined the patient to be a poor surgical candidate, but given the likelihood of pulmonary and systemic embolization, an intervention was required. We proposed AngioVac-assisted vegetation debulking of the tricuspid valve to be the best approach in consideration of the small aortic valve vegetation and lung cancer. He successfully underwent this procedure and was discharged on postprocedure day 2.
