Case Report: the transcatheter extraction of an atrial mass (TEXAS) technique.

Background: Intracardiac masses are historically treated with surgery. As percutaneous technologies continue to evolve, non-surgical techniques for mass removal may become options. We present a case of a woman with a large right atrial mass that was percutaneously removed en bloc without surgery.
Case Summary: A 77-year-old woman presents with a 40 mm right atrial mass. The mass was increasing in size, and she preferred to avoid surgical removal. The tumour was removed percutaneously from the femoral vein using a large suction cannula in combination with transection of the stalk using an electrified snare. The case was complicated by a haemopericardium that was treated successfully by injecting a haemostatic matrix into the pericardial space. The pathology returned papillary fibroelastoma.
Discussion: The TEXAS technique used to remove the right atrial mass in this case is a modification of a previously described technique (SEATTLE procedure). Using this method, we were able to remove a 40 mm tumour from the right atrium without surgery. This is the largest reported intracardiac tumour that has been removed en bloc percutaneously. Percutaneous removal of right atrial tumours appears feasible, although this may be limited to smaller tumours based on the results of our case.
