Intra-procedural transesophageal echocardiography showing an intense smoke in the left atrium and left auricle appendage (A). To prevent cerebral embolization during the procedure, a cerebral protection system (SENTINELTM) was advanced from the right radial artery to the aortic arch and positioned with its ‘’baskets” at the level of the brachiocephalic (BA) and left carotid arteries (LCA) (B).
