Abstract:
The use of peripherally inserted central catheters (PICCs) has expanded substantially for drug delivery in clinical practice in recent years. However, PICC lines expose patients to potential complications associated with an increasing incidence of infective endocarditis. We herein report a case of a 57-year-old woman who was diagnosed with tricuspid valve endocarditis by echocardiography. The most probable cause was direct injury to the tricuspid valve by the tip of a PICC line with excessive length in the right heart. The vegetation disappeared with conservative treatment after removal of the PICC line. Clinicians must maintain vigilance against any suspected PICC-related infection in febrile patients with a PICC line. For echocardiographers, precise evaluation of the position of the PICC tip and the detection of endocarditis is important to devise the optimal clinical strategy.
