6 Committee comments
6.1 The risk of needing a permanent pacemaker and other complications after the procedure depends on the technique and the type of valve used.
6.2 There is a move towards using sedation rather than general anaesthesia for this procedure.
6.3 The longer-term evidence on transcatheter aortic valve implantation (TAVI) is from earlier generation TAVI devices and the technology is evolving. Longer-term evidence is needed and this should be taken into account by the multidisciplinary team.
6.4 TAVI offers a potential treatment for patients with aortic stenosis for whom surgical aortic valve replacement would not be suitable.
