Transcatheter Aortic Valve Implantation Without General Anaesthetic.

Transcatheter aortic valve implantation (TAVI) procedures are increasingly being performed under local anaesthetic, generally with sedation. Operators hope this will reduce mortality, morbidity and length of hospital stay. A general anaesthetic (GA), however, although involving intrinsic risk, permits transoesophageal echocardiogram (TOE) imaging throughout a procedure as well as eliminating patient anxiety, pain and movement. This article reviews the published literature, all single-centre experiences, comparing TAVI procedures performed with and without a GA. Procedures performed without GA are generally shorter with reduced length of stay compared with those performed under GA. There is no evidence of any difference in outcomes.
