Aortic Rupture and Hemorrhagic Shock After Percutaneous Retrieval of an Embolized Left Atrial Appendage Occluder.

Left atrial appendage (LAA) closure may be complicated by occluder embolization. Percutaneous retrieval is preferred for devices embolized to large vessels. In this report, the successful percutaneous retrieval of an LAA occluder embolized to the abdominal aorta was followed by several complications, culminating in iatrogenic aortic rupture requiring endovascular repair. (Level of Difficulty: Advanced.).
