Retrospective Analysis of Procedural Aspects of Transcatheter Aortic Valve Implantation (TAVI) on Peri-procedural Stroke

Retrospective Analysis of Procedural Aspects of Transcatheter Aortic Valve Implantation (TAVI) on Peri-procedural Stroke Rates in the United Kingdom

Retrospective analysis of all patients receiving TAVI in the United Kingdom (UK). Stroke rates following TAVI are roughly 3%. There are several device and procedure related characteristics which may increase the risk of stroke. We will examine if there is a signal in the UK registry. This will be important is TAVI is to be extended down to lower risk patient cohorts.

Factors to be examined include (but not limited to):

need for Pre-procedure Balloon aortic Valvuloplasty (BAV) Need for two valves need for post-dilatation need for rapid ventricular burst pacing

Inclusion Criteria:

• Had TAVI procedure in UK
