Abstract

A 70-year-old man was referred to our hospital for an intermittent high fever attributed to subcutaneous pocket infection of an implanted central venous access port device caused by methicillin-resistant staphylococcus aureus and subsequent bloodstream infection. Echocardiography revealed a large vegetation on the posterior tricuspid leaflet, annular dilatation and moderate-to-severe tricuspid regurgitation. Valve surgery was performed for persistent infection despite 8 weeks of antibiotics therapy. At operation, vegetations and torn chordae tendineae were found on the posterior tricuspid leaflet. After total resection of the posterior tricuspid leaflet, bicuspidalization valvuloplasty with prosthetic ring annuloplasty was achieved without relapse of the infection or residual regurgitation.
