Abstract:
Objective To compare the differences in intraoperative radiation exposure between leadless and transvenous pacemaker implantation. Methods Cumulative dose (CD), dose area product (DAP), and fluoroscopy time during procedure were recorded and analyzed in 21 patients with leadless pacemaker implantation (Micra group), 55 patients with transvenous single-chamber pacemaker implantation (VVI group), and 216 patients with transvenous dual-chamber pacemaker implantation (DDD group). Results The fluoroscopy times of the Micra group, VVI group, and DDD group were 5.0 ± 1.9, 4.8 ± 1.4, and 7.6 ± 1.9 min, respectively (P < 0.001). Their CD values were 203.5 ± 76.1, 147.0 ± 41.0, and 249.6 ± 58.2 mGy, respectively (P < 0.001). Their DAP values were 18.6 ± 7.1, 13.4 ± 3.9, and 22.6 ± 5.6 Gy·cm2, respectively (P < 0.001). Compared with the VVI group, the Micra group had similar fluoroscopy time (P=0.813) but higher CD (P=0.010) and DAP values (P = 0.012). Compared with the DDD group, the Micra group had reduced fluoroscopy time (P < 0.001), CD value (P = 0.033), and DAP value (P = 0.047). Conclusion Leadless pacemaker implantation is associated with increased radiation exposure compared to transvenous single-chamber pacemaker implantation. However, it offers a significant advantage in reducing radiation exposure for both medical staff and patients compared to transvenous dual-chamber pacemaker implantation.
