Need for a Permanent Pacemaker after Transcatheter Aortic Valve Implantation
A permanent pacemaker is commonly required in patients undergoing transcatheter aortic valve implantation (TAVI) at ranges up to 30-50%. In general, the incidence is higher with the self- vs balloon-expandable valves. Several risk factors have been identified. Importantly, pacemaker implantation does not seem to improve prognosis and this needs to be further explored. Finally, new generation valves appear to increase the complication of AV block and need for permanent pacing. These issues are herein briefly reviewed.
