Summary: | Purpose
Optimal atrial pacemaker lead position and fixation mechanism have not been determined with regard to effect on complications. We aimed to determine the association between atrial lead-related complications and varying atrial lead tip positions and lead fixation mechanisms.
Methods
All patients who underwent dual-chamber pacemaker implant between 2004 and 2014 were retrospectively reviewed for atrial lead tip position and fixation type. Lead-related complications were assessed by electronic medical record review. Complication rates were compared at 1 year by chi-square analysis and at 5 years using a Kaplan-Meier analysis.
Results
During the study period, 3451 patients (mean age 73.9, 53.4 % male) underwent dual-chamber pacemaker placement. Active fixation leads were associated with a higher incidence of pericardial effusion (81 (2.9 %) vs. 6 (1.0 %),
p
= 0.005) and pericardiocentesis (46 (1.6 %) vs. 2 (0.3 %),
p
= 0.01) at 1 year compared to passive fixation leads. There was no difference in overall complication rates by fixation type (161 (5.7 %) vs. 29 (4.6 %),
p
= 0.26). Low atrial septal lead tip position was associated with a higher rate of lead dislodgement (10 (15.2 %)) compared to appendage (46 (1.6 %)), free wall (10 (2.1 %)), or high atrial septal (2 (4.7 %)) positions (
