Purpose Of Review: The field of cardiac pacing has undergone significant evolution with the introduction and adoption of conduction system pacing (CSP) and leadless pacemakers (LLPMs). These innovations provide benefits over conventional pacing methods including avoiding lead related complications and achieving more physiological cardiac activation. This review critically assesses the latest advancements in CSP and LLPMs, including their benefits, challenges, and potential for future growth.
Recent Findings: CSP, especially of the left bundle branch area, enhances ventricular depolarization and cardiac mechanics. Recent studies show CSP to be favorable over traditional pacing in various patient populations, with an increase in its global adoption. Nevertheless, challenges related to lead placement and long-term maintenance persist. Meanwhile, LLPMs have emerged in response to complications from conventional pacemaker leads. Two main types, Aveir and Micra, have demonstrated improved outcomes and adoption over time. The incorporation of new technologies allows LLPMs to cater to broader patient groups, and their integration with CSP techniques offers exciting potential.
Summary: The advancements in CSP and LLPMs present a transformative shift in cardiac pacing, with evidence pointing towards enhanced clinical outcomes and reduced complications. Future innovations and research are likely to further elevate the clinical impact of these technologies, ensuring improved patient care for those with conduction system disorders.

We present the case of a 64-year-old man who, during the implantation of an active-fixation leadless pacemaker (LP, Aveir VR, Abbott, USA), underwent several external defibrillation shocks up to 240 Joules, due to symptomatic sustained supraventricular tachycardia at 160 bpm. The shocks, delivered both before and after the screwing of the device in the low interventricular septum, did not cause any technical damage to the device, and no complications were observed. The device was then deployed successfully.

Background: Temporary transvenous pacing (TTP) is a common procedure, predominantly performed in the catheterization laboratory (cath lab) because of presumed lower complication rate. This study aims to evaluate the efficacy and safety of TTP placement in the ICU compared to TTP placement in the cath lab.
Methods: This retrospective, real-life study included all patients requiring TTP in a tertiary care ICU between 2019 and 2022.

An infant with DiGeorge syndrome, multiple comorbidities, and truncus arteriosus type II underwent repair complicated by heart block necessitating placement of a dual-chamber bipolar pacing system with right ventricular leads and subsequent resynchronization with placement of left ventricular apical pacing leads. Resynchronization therapy improved QRS duration from 180 ms to 100 ms and ejection fraction from 25% to 54% over the course of 4 weeks with gradual return to normal function and eventual discharge.

The aim of this study was to assess the frailty status of patients with heart failure undergoing CRT-D and then explore the predictive value of frailty for all-cause mortality and heart failure-related readmissions in these patients. We retrospectively included 374 patients with chronic heart failure who underwent CRT-D treatment at the First Affiliated Hospital of Xinjiang Medical University between June 2020 and June 2024. Based on the Tilburg Debilitation Assessment Scale, 175 patients (46.

Introduction: In patients with symptomatic, refractory atrial fibrillation the ablate and pace (A&P) strategy (pacemaker implantation followed by atrio-ventricular junction ablation (AVJA)) is superior to medical therapy in improving quality of life and prognosis. Despite its well-proven benefits, this invasive therapeutic option is still underutilized in clinical practice. The choice of pacing modality (right ventricular pacing, biventricular pacing, BVP, or conduction system pacing, CSP) is crucial and can have significant clinical implications.
