Background: Leadless pacemakers are widely used, but the quality of life assessment of patients with leadless pacemakers is still unclear. Hypothesis: Assume that leadless pacemakers can improve the patients' quality of life. Methods: Total of 119 patients who received pacemaker implantation at Beijing Anzhen Hospital from January 2020 to March 2022 were selected, including 35 leadless pacemakers and 84 conventional pacemakers. The SF‐36 questionnaire was used to evaluate quality of life at baseline, 1 month and 3 months after surgery. We also used a questionnaire consisted of 4 specific questions related to the implant procedure to assess the surgery. Results: There were no differences in baseline characteristics between the two groups, except for age and oral anticoagulant treatment. There was no difference in baseline SF‐36 scores. At the 3‐month follow‐up, patients in leadless pacemakers group were significantly better at physical function (63.63 vs 47.50, p =.000), role physical (60.20 vs 40.23, p =.000), bodily pain (65.57 vs. 61.69, p =.042), physical component summary (61.25 vs. 50.57, p =.000), vitality (56.26 vs 49.57, p =.001), social function (80.14 vs 74.70, p =.004), role emotional (76.14 vs. 71.42, p =.015), mental health (75.46 vs. 68.18, p =.000), mental component summary (72.00 vs. 65.97, p =.000), even after adjusting for clinical baseline and SF‐36 baseline. Pacemaker‐related discomfort and mobility limitations were significantly reduced in leadless pacemakers group. Conclusions: Leadless pacemakers is associated with better quality of life with less activity limitations due to surgical discomfort and less emotional distress. However, current use of leadless pacemakers in China is limited due to the high cost. [ABSTRACT FROM AUTHOR]

The Micra TPS™ (Medtronic) is the first leadless pacemaker listed in China. The best fluoroscopic angle for the intraoperative fixation test is selected according to different implantation sites to reduce the fluoroscopy duration and radiation dose, and the test is based on the early safety and effectiveness of the device after implantation. A total of 110 patients who underwent Micra TPS™ implantation were selected. Eighty patients were in group A, and 30 patients were in group B. Under the guidance of the conclusions from group A, the fluoroscopy duration, radiation dose and number of fluoroscopic positions of the best fluoroscopic angle of the fixation test according to different positions of the implanted interventricular septum were compared. In 85.0% of the group A implants, these angles were based on the right interior oblique (RAO) angle, with 48.5% cranial (CRA) and 29.4% caudal (CAU) angles. The angle of the tilting head side of the RAO angle was prioritized in group B, and referring to the average angle data, the average fluoroscopy duration for finding the best angle of fixation test was 1.7 ± 0.6 vs. 3.2 ± 1.8 min (P < 0.001), the average radiation dose was 270.4 ± 56.3 vs. 338.1 ± 112.9 mGy (P = 0.002), and the average number of fluoroscopic positions was 2.2 ± 0.6 vs. 4.2 ± 2.1 (P < 0.001), which was significantly less than that in group A. This study found that there was regularity in the fluoroscopic angle for the fixation test during Micra TPS™ operation.Level of Evidence Level 3, local nonrandom sample., (© 2022. The Author(s).)
