Transjugular Approach for Implantation of Active Fixation Leadless Pacemakers

Brief Summary

This study is a prospective, single-arm, single-center feasibility study evaluating the safety and feasibility of transjugular (internal jugular vein) implantation of the Aveir VR leadless ventricular pacemaker in patients requiring ventricular pacing. A total of 15 patients will be enrolled at Xijing Hospital. The primary objective is to assess procedural feasibility and acute safety (from intraoperative to 48 hours post-procedure). Secondary objectives include short-term (1 to 3 months) pacing parameter stability (threshold, R-wave amplitude, impedance), technical success rate, procedure-related metrics, and adverse event rates.
