The historical restriction of magnetic resonance imaging (MRI) for patients with cardiac implantable electronic devices (CIEDs) has been lifted by certified MRI-conditional systems in recent years. Mixed-brand CIED systems consisting of a generator from one manufacturer and at least one lead from another manufacturer are not certified for MRI. We evaluated the temporal trend in the prevalence of mixed-brand systems in the era of MRI-conditional systems.

Introduction: Transvenous lead extraction (TLE) is generally considered a safe procedure, albeit not without risks. While gender-based disparities have been noted in short-term outcomes following TLE, a notable gap exists in understanding the long-term consequences of this procedure. The objective of this analysis was to investigate sex differences in both acute and long-term outcomes among patients who underwent TLE at a tertiary referral center.

Article Synopsis
  • - The study analyzed outcomes of leadless pacemakers (LPMs) in patients with varying stages of chronic kidney disease (CKD) collected from the international i-LEAPER registry, focusing on major complications and electrical performance post-implantation.
  • - Results indicated that while patients with CKD experienced similar rates of major complications during and after LPM implantation compared to those with normal kidney function, all-cause mortality was notably higher in severe CKD stages (G4/G5).
  • - Additionally, patients with CKD displayed a slightly increased pacing threshold during the initial follow-up month, but overall, LPM electrical performance remained comparable across all groups. The research suggests that patients with advanced CKD are less frequently represented in LPM procedures despite

Article Synopsis
  • Subclinical atrial fibrillation (AF) increases risks of developing clinical AF, stroke, and cardiovascular death; researchers aimed to test if closed loop stimulation (CLS) could reduce atrial high-rate episodes (AHREs) in pacemaker patients compared to conventional dual-chamber rate-adaptive pacing (DDDR).
  • A study with 1,210 patients showed that those using CLS had a lower incidence of the primary endpoint (first AHRE lasting ≥6 min, stroke, or TIA) compared to DDDR over a 3-year period, particularly effective in patients without atrioventricular block or AF history.
  • The findings suggest that dual-chamber CLS significantly reduces AHRE occurrence, highlighting its potential benefits for patients

Background: Atrial high-rate episodes (AHREs) are frequent in patients with cardiac implantable electronic devices. A decrease in device-detected P-wave amplitude may be an indicator of periods of increased risk of AHRE.

Objective: The objective of this study was to assess the association between P-wave amplitude and AHRE incidence.
