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).
