500 Cedenilla et al. Requirements for permanent pacemaker afterTAVI Int J Cardiovasc Sci. 2019;32(5):492-504 Original Article Figure 3 - Permanent pacemaker-free survival after transcatheter aortic valve implantation and comparison between pacemaker-free survival in patients undergoing CoreValve ® implant and in patients undergoing implantation of other prostheses. patients who needed a pacemaker had the CoreValve ® prosthesis implanted. Other authors also demonstrated that the need for a permanent pacemaker with the CoreValve ® prosthesis is significantly higher compared to the Sapien ® prosthesis. 16-19,21-24 In the study by Piazza et al., who used the CoreValve ® prosthesis, the pacemaker implant rate was 19% in 91 patients evaluated. 22 In the PARTNER study, which used Sapien ® prostheses, this rate was 3.8% in 699 patients evaluated up to 30 days after the procedure. 10 In the study by Aktug et al., 20 of the 72 patients (28%) who had the CoreValve ® prosthesis implanted required a permanent pacemaker, whereas only 4 of the 82 patients (5%) who had Sapien ® implanted required the device. 35 Due to its longer length (53 to 55 mm), the CoreValve ® prosthesis extends from the ascending aorta to the LV Free from permanent pacemaker implantation Days of follow up after TAVI Free from permanent pacemaker implantation
