Intracardiac cement embolism resulting in tricuspid regurgitation

Bone cement leakage is a common complication after percutaneous kyphoplasty. In rare cases, leakage into the venous system occurs, which can be life-threatening, especially when it embolizes the heart. Here, we present a case of cement embolization of the right ventricle with tricuspid valve involvement. A 69-year-old woman with an asymptomatic severe tricuspid valve regurgitation was referred to our department. She had a history of balloon kyphoplasty because of osteoporotic collapsed vertebrae in 2010. Echocardiography showed a foreign body attached to the right ventricle, prolapsing into the right atrium and causing a severe tricuspid valve regurgitation. The foreign body was surgically removed, and the tricuspid valve was replaced with a biological valve. The foreign body was analysed by scanning electron microscopy and element analysis. Zirconium was identified within the foreign body, which is an additive in bone cement used in orthopaedic surgery. Intracardiac cement embolism following percutaneous kyphoplasty is a rare but life-threatening complication. Here, we present a case of tricuspid valve destruction caused by the long-term presence of an intracardiac foreign body, specifically a cement embolus
