Conduction recovery and avoidance of permanent pacing after transcatheter aortic valve implantation.
Transcatheter aortic valve implantation (TAVI) is an established treatment option for patients with severe aortic stenosis and high surgical risk. Currently, various prosthesis types are available. Atrioventricular block (AVB) requiring pacemaker (PM) implantation is a typical complication after TAVI. This study investigated the recovery of AV node conduction and mid-term outcome of patients with or without PM implantation after TAVI according to prosthesis type. ⋯ Mid-term all-cause survival after TAVI seems to be independent of prosthesis type and PM implantation after TAVI. Intrinsic AV node conduction recovers in a significant proportion of patients. Therefore, regular PM interrogations including reprogramming are required to avoid unnecessary permanent right ventricular stimulation.
