Trends in replacement of pacemaker leads in the Netherlands: A long-term nationwide follow-up study.

Background: Our objective was to investigate trends over time in longevity and reasons for replacement with or without extraction of pacemaker leads after first implantation.

Methods: Data collected between 1984 and 2006 in the national Dutch pacemaker registry were used. This registry covered 84% of sold leads.

Leadless pacemaker versus transvenous single-chamber pacemaker therapy: A propensity score-matched analysis.

Background: The recent introduction of leadless pacemakers (PMs) was aimed to eliminate transvenous lead- and pocket-related complications. While the initial results with the leadless PMs seem promising, the nonrandomized nature, limited implant experience of operators, and short follow-up period of these studies preclude a simple comparison to transvenous PMs.

Objectives: The objective of this study was to provide a balanced comparison of leadless and transvenous single-chamber PM therapies through a propensity score-matched analysis.

Trends in service time of pacemakers in the Netherlands: a long-term nationwide follow-up study.

Aims: After decades of experience and strongly improved technology, service time of pacemaker generators is expected to increase. To test this hypothesis, we conducted a retrospective review of a large cohort of patients with a pacemaker.

Methods: We reviewed data collected between 1984 and 2006 in the first national Dutch pacemaker registry.
