Procedure success rate and complications
All studies exclusively used a fixed curve sheath (C315 HIS, Medtronic
Inc., Minneapolis, MN, USA) and the Select Secure pacing lead (model
3830, Medtronic Inc., Minneapolis, MN, USA) except for Wu et al.,in whose study also used a deflectable delivery system (C304, Medtronic
Inc., Minneapolis, MN, USA)22. The overall implant
success rate was 88.3%, ranging from 77.5% to 98%. The most common
reason for implant failure was difficulty/inability to penetrate the
septum, representing 41.67% of all failures.
Eight studies reported procedure-related complications (Table 3). There
were 15 complications observed in 245 patients. The most commonly
reported complication was transient right bundle branch injury (14 total
complications). The only other complication reported was one case of
lead dislodgement.
