Stroke events after transcatheter aortic valve implantation: Temporal relationships and affected brain regions

Most strokes occurred early after TAVI - but not necessarily during the procedure - and affected multiple brain regions only partially protected by current CEP devices. Efficient prevention of cerebrovascular events may require strategies beyond the TAVI procedure to minimize stroke risk and additional randomized controlled trials will be required to clarify the role of CEP in efficient stroke prevention during TAVI.
