First-in-man report of transsubclavian venous implantation of the Aveir leadless cardiac pacing system

IntroductionTranssubclavian venous implantation of the Aveir leadless cardiac pacemaker (LCP) has not been previously reported.Methods and ResultsThree cases of transsubclavian implantation of the Aveir LCP are reported. Two cases were postbilateral orthotopic lung transplant, without appropriate femoral or jugular access due to recent ECMO cannulation and jugular central venous catheters. In one case, there was strong patient preference for same-day discharge. Stability testing confirmed adequate fixation and electrical testing confirmed stable parameters in all cases. All patients tolerated the procedure well without significant immediate complications.ConclusionsWe demonstrate the feasibility of transsubclavian implantation of the Aveir LCP.
