An 83-year-old man with severe organic mitral regurgitation underwent mitral valve surgery with implantation of a biologic prosthesis. Four months later he presented with hemolytic anemia and heart failure due to severe paravalvular regurgitation. Since the patient refused surgery, the paravalvular leak was closed percutaneously using two Amplatzer devices, with angiographic and clinical success. Two months after the intervention he developed heart failure again and embolization of one of the devices was documented, with significant worsening of paravalvular regurgitation. A redo percutaneous closure was attempted but although initially promising, was ultimately unsuccessful as heart failure symptoms and hemolytic anemia persisted. Surgical correction was the final solution for this case. This is the second case of late device embolization reported in the literature and highlights the importance of careful long-term follow-up of such patients, as late complications, although rare, may occur.
