Procedural complications: stroke

TAVI within failing surgical aortic bioprostheses

Rates of stroke are low today in transcatheter aortic valve implantation (TAVI) and despite the inherent challenges of dealing with degenerate surgical bioprostheses, recent registries have shown that the rate of stroke in TAV-in-SAV procedures is similar to that seen in TAVI performed in native valves. This section explores this situation in detail, looking specifically at the TAV-in-SAV procedure and examines what needs to be done to ensure that the risks for this complication remain low.
