Abstract:
A 59-year-old male with a history of mitral valve replacement several years previously was admitted to the authors' institution with symptoms of advanced heart failure. Echocardiography showed a severe paravalvular dehiscence and surgery was discouraged due to high perioperative risk. A first transcatheter leak closure was unsuccessful despite the correct deployment of various occluding devices. A second percutaneous attempt was carried out with implantation of three Amplatzer Vascular Plug® III devices (five occluders were positioned in total within the oblong defect), leading to a mild residual leakage. Device embolism occurred twice during the procedure but was resolved using adequate catheter retrieval techniques.
