The risk of liberating embolic debris is inherent to most, if not all, structural heart interventions. Large-bore device placement within the heart chambers, particularly via a transseptal or transaortic approach, and substantial interaction with cardiac structures may release acute or chronic thrombus, cardiac tissue, and device-related material into the bloodstream. One major consequence, cerebral embolism, is one of the most dreadful periprocedural complications of left-sided structural heart interventions. Ongoing research on cerebral embolic protection devices aims to further improve outcome in patients undergoing transcatheter aortic valve replacement (TAVR)1.

Cerebral embolism in mitral valve interventions has received considerably less attention, ...
