Out with the old: Single center experience with transvenous extraction of leads older than 15 years.

Abstract

Lead dwell time is the single strongest predictor of failure and complications in transvenous lead extraction. To report the success rate and complications of transvenous lead extractions with implant dwell time of at least 15 years. Procedural and patient data were prospectively collected into a database. The excimer laser was the primary method for lead extraction with the use of mechanical rotational sheaths and femoral snares at operator discretion. A total of 442 patients between 2011 and 2020 underwent lead extraction (705 leads) primarily for infection or device failure at our high-volume center. Forty-one patients with 71 leads>15 years old were included in this cohort. Mean patient age was 53.5 ± 18.5 years, 67.5% were male. Mean lead dwell time was 19.6 ± 4.4 years. Thirty-six of 41 (88%) patients had successful extraction of all leads compared to 96% in the remaining 401 patients, p value.004. Of the five patients without fully successful extractions two of these patients had abandoned leads (three total) that were clinically significant. There were two (4.9%) major complications in the very old lead group and six (1.5%) in the other group. In the very old lead group, one patient experienced right atrial appendage perforation requiring surgical repair and recovered well. One patient experienced new complete heart block requiring 2 min of CPR but did well thereafter. There was no procedure-related mortality. Despite challenges posed by older leads, very old leads can be safely and effectively extracted with low complication rates.
