A novel focal lattice-tip catheter toggling between pulsed field energy and radiofrequency for atrial arrhythmia ablation: Results from a real-world, multicenter registry.

Background: A novel focal lattice-tip catheter allowing the delivery of either pulsed field (PF) or radiofrequency (RF) energy has recently received regulatory approval. The technology features a proprietary 3-dimensional electroanatomic mapping system.

Objective: We describe the first real-world and multicenter experience.

Ultrasound-guided versus fluoroscopy-guided axillary vein puncture for cardiac implantable electronic device implantation: a meta-analysis enrolling 1257 patients.

Introduction: Ultrasound-guided (Echo-AVP) and Fluoroscopy-guided Axillary Vein Puncture (Fluoro-AVP) are both acknowledged as safe and effective techniques for transvenous implantation of leads for cardiac implantable electronic devices (CIEDs). Nonetheless, it is still debated which of the two techniques has a better safety and efficacy profile. Therefore, we performed a meta-analysis to evaluate the efficacy and safety of Echo-AVP versus Fluoro-AVP for CIEDs implantation.

From trendsetters to second movers: Commitments as catalysts for social change.

This paper examines the dual role of commitment in accelerating the mitigation of maladaptive norms. By drawing on the literature on social norms and commitment, I analyze how commitments (i) explain the deviant behavior of trendsetters and (ii) expedite social change by prompting counterpreferential choices among second movers. Specifically, the paper explores two key aspects of this dynamic: (1) the importance of moral norms, particularly in the relationship between trendsetters' commitments and their unconditional preferences, and (2) the unique role of second movers, whose commitment to trendsetters can lead them to make choices that contradict their conditional preferences in favor of trendsetters' behavior.
