Tricuspid valve endocarditis following peripheral venous cannulation – an unusual aetiology

Isolated tricuspid valve endocarditis is rarely seen without intravenous drug abuse, invasive cardiac procedure or previous valvular disease. Another often overlooked but rarely seen risk factor is peripheral intravenous cannulation. In such cases poor cannula line care and unhygienic practices predispose patients to right sided infective endocarditis. The patient in this case developed tricuspid valve endocarditis following treatment for Dengue Hemorrhagic fever. He had pulmonary involvement as well. Blood culture was positive with MRSA and he was treated with prolonged course of IV antibiotics without surgical interventions. Eventually, he recovered completely and was discharged after 8 weeks of hospital stay.
