Left atrial appendage (LAA) elimination is regarded to protect patients with atrial fibrillation (AF) from stroke or embolism. The Watchman occluder is a device for percutaneous LAA occlusion and is at present investigated in the PROTECT AF trial. In a 78-year-old man, embolization of the Watchman device occurred 10 minutes after implantation. At emergency cardiac surgery, the device was removed from the aortic valve and an aortic bioprosthesis and a pacemaker had to be implanted. One year postoperatively, he still suffers from heart failure. This case shows that percutaneous LAA occlusion may result in serious complications.
