D-PO02-097 - Long-term Performance Of Small Tip And Non-corticosteroid Eluding Selectsecure™ Leads Compared To Small Tip Corticosteroid Eluding Fineline™ Lead (ID 202)

Abstract

Background: HIS bundle pacing (HBP) is an emerging method of physiological pacing. The lead used for HBP is a small tip and non-corticosteroid eluding lead. There are reports of capture threshold rise over the time attributable to the lead size and non-corticosteroid eluding nature of the lead.
Objective: To evaluate the long-term performance of a small tip non-corticosteroid eluding lead in non-HIS position when compared to another small tip corticosteroid eluding lead
Methods: In this study, the long-term performance of 393 SelectSecure™ leads in non-HIS position with maximum follow up of 10 years compared to 96 FineLine™ leads in non-HIS position with maximum follow up of 10 years.
Results: 393 SelectSecure™ leads were implanted in patients with mean age of 71.8±12.8, and 56% of the patients were male. The mean capture threshold at implantation and after 10 years was 0.9±0.8V@0.4ms and 1±0.4V@0.4ms respectively. The mean lead impedance at implantation and after 10 years was 706±175Ω and 543±122Ω respectively (Figure-1). 96 FineLine™ leads were implanted in patients with mean age of 78±11.4, and 66% of the patients were male. The mean capture threshold at implantation and after 10 years was 0.6±0.4V@0.4ms and 0.9±0.3V@0.4ms respectively. The mean lead impedance at implantation and after 10 years was 556±105Ω and 607±205Ω respectively (Figure-1)
Conclusion: SelectSecure and FineLine leads had stable long-term capture thresholds and impedances. Corticosteroid eluding tip in small size leads did not make significant difference in long-term lead performance in non-HIS position.
