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.

与小叶损伤相关的三尖瓣赘生物：导管错位的独特问题。

近年来，在临床实践中，外周插入中心导管 (PICC) 的使用已大大扩展用于药物输送。然而，PICC 线使患者面临与感染性心内膜炎发病率增加相关的潜在并发症。我们在此报告一例超声心动图诊断为三尖瓣心内膜炎的 57 岁女性。最可能的原因是右心 PICC 导管末端过长直接损伤三尖瓣。拔除 PICC 线后，经保守治疗，植被消失。临床医生必须对使用 PICC 线的发热患者的任何疑似 PICC 相关感染保持警惕。对于超声心动图医师，
