title: Pacemaker implantation after transcatheter aortic valve implantation.
abstract: Thirty- to 35% of patients after transcatheter aortic valve implantation undergo implantation of a permanent pacemaker (PPM) because of development of atrioventricular block (AVB) or development of a condition with high risk of progression to AVB. There are insufficient data regarding long-term follow-up on pacing dependency. From February 2009 to July 2011, 191 transcatheter aortic valve implantation procedures were performed at the Rabin Medical Center (125 CoreValve and 66 Edwards SAPIEN). Thirty-two patients (16.7%) received a PPM (30 with CoreValve and 2 with Edwards SAPIEN). Data from the pacemaker clinic follow-up was available in 27 patients. After a mean follow-up of 52 weeks (range, 22 to 103), only 8 (29%) of 27 patients were pacing dependent. The indication of PPM in these 8 patients was complete AVB. In conclusion, in our center, the rate of PPM implantation was 16%, which is lower than that reported in the published works. Only 29% of those patients implanted with PPM were pacemaker dependent. Further studies are necessary to define reliable predictors for long-term pacing.
