Comparison of Lead Complications with Polyurethane Tined, Silicone Rubber Tined, and Wedge Tip Ventricular Pacemaker Leads
A prospective study of lead-related complications was undertaken over a five year period to compare unipolar tined endocardial pacemaker leads with silicone rubber insulation (SR), to those with polyurethane insulation (PU). Overall complications were similar in both groups - 3.6% for the 364 SR leads and 4.2% for the 238 PU leads.
The total series of 602 tined leads (SR + PU) was then compared to a retrospective review of 220 wedge tip silicone rubber ventricular leads. A marked reduction was demonstrated in dislodgements (0.3% vs 7.7%, P < 0.001) reoperations (2.0% vs 15.0%, P < 0.001) and total complications (3.8% vs 15.5%, P < 0.001) with tined leads. We conclude that tined ventricular leads are far superior to wedge tip leads with respect to lead complications. There were no significant differences between the two types of tined leads used in this study.
