title: Coil embolization of left ventricular outflow tract pseudoaneurysms: techniques and 5-year results.
abstract: We present 3 cases of percutaneous coil embolization of left ventricular outflow tract (LVOT) pseudoaneurysms. All patients had a history of repetitive aortic root surgery and/or inflammatory disease. Computed tomography showed pseudoaneurysms connecting the sacs to the LVOT lumen. In each case, a 6-Fr catheter was advanced to the sac by the transfemoral approach. A 0.052-in coil was placed across the tract. There was no significant complications associated with the procedure. No recurrence was evident in any case during the 5-year follow-up. Coil embolization may be an effective treatment for these pseudoaneurysms in patients with complicated histories of aortic root surgery.
