Prevention of esophageal lesions during atrial fibrillation catheter ablation using esophageal temperature monitoring: A systematic review and meta ‐analysis
ConclusionsThe use of ETM does not reduce the incidence of EDELs during RF AF ablation. The higher energy delivered on the posterior wall is likely attributable to a false sense of safety that may explain the lack of benefit of ETM. Further randomized controlled trials are needed to provide conclusive results. (Source: Pacing and Clinical Electrophysiology : PACE)

Informational letters or postcards to initiate remote monitoring among veterans with pacemakers and implantable cardioverter ‐defibrillators: A randomized, controlled trial
ConclusionsThis randomized trial showed no significant difference in the proportion of chronically non-adherent patients who sent an RM transmission after receiving a low-cost postcard or a detailed, higher-cost letter encouraging their participation in RM. However, as only a minority of patients responded to either, further work is needed to engage patients in the life-saving benefits of RM. (Source: Pacing and Clinical Electrophysiology : PACE)

Elucidating left atrial electrical potential with microelectrode catheter: A case of coronary sinus ostial atresia with small persistent left superior vena cava
AbstractA 51-year-old woman presented with recurring palpitations. Electrocardiography revealed narrow QRS tachycardia with short RP configuration. Computed tomography showed coronary sinus (CS) ostial atresia along with a small persistent left superior vena cava (PLSVC). Electrophysiological study identified the retrograde earliest atrial activation site (EAAS) at the CS ostium without decremental properties, and para-Hisian pacing suggested retrograde atrioventricular nodal conduction. Using a 1.6-Fr microelectrode catheter distally placed in the CS via the PLSVC, EAAS was confirmed within the left atrium, not the CS ost...

Transvenous lead advancement in pediatric pacing to overcome growth ‐induced lead straightening and stretching
Conclusionthe advancement of transvenous leads in children seems safe and effective. This procedure may be another possible choice to preserve transvenous lead position and function until growth has completed. (Source: Pacing and Clinical Electrophysiology : PACE)

Different methods of 3D QRS area calculation from vectorcardiographic X, Y, and Z Leads
Abstract3DQRSarea is a strong marker for cardiac resynchronization therapy and can be obtained by taking the (i) summation or the (ii) difference of the areas subtended by positive and negative deflections in X, Y, Z vectorcardiographic electrocardiogram (ECG) leads. We correlated both methods with the instantaneous-absolute-3D-voltage-time-integral (VTIQRS-3D). 3DQRSarea consistently underestimated the VTIQRS-3D, but the summation method was a closer and more reliable approximation. The dissimilarity was less apparent in left bundle branch block (r2 summation  .996 vs. difference .972) and biventricular paced ECGs (r2�...

Meta ‐analysis of pulsed‐field ablation versus cryoablation for atrial fibrillation
ConclusionThe utilization of PFA provides a safer, time-saving, and tissue-specific procedure compared to CBA, while maintaining comparable success rates. This has the potential to enhance procedural efficiency and optimize resource utilization in clinical practice. These findings underscore the feasibility and promise of PFA as an alternative technique for PVI in patients with AF. (Source: Pacing and Clinical Electrophysiology : PACE)

Iatrogenic vertebral artery injury during catheter ablation treated using coil embolization
AbstractThe internal jugular vein (IJV) is occasionally used for blood access during catheter ablation. Additionally, accidental injury of the vertebral artery during an IJV puncture is a rare complication that can result in catastrophic events, such as death. However, vascular access complications cannot be completely prevented despite the introduction of ultrasound-guided punctures. Here, we present a case of a patient with symptomatic paroxysmal atrial fibrillation that required catheter ablation. (Source: Pacing and Clinical Electrophysiology : PACE)

Cryoballoon pulmonary vein isolation versus radiofrequency ablation of the pulmonary veins and left atrial posterior wall: Patient ‐reported outcomes

Intracardiac echocardiography ‐guided catheter ablation of highly symptomatic accelerated idioventricular rhythm originating from the right ventricular apical diverticulum
AbstractVentricular diverticula are saccule-like structures formed by the protrusion of the ventricular myocardium from the endocardial surface towards the free wall. Most diverticula are muscular structures, and patients usually have no obvious clinical symptoms. However, diverticula may contribute to arrhythmogenesis due to localized myocardial structural disturbances. Right ventricular apical diverticulum (RVAD) is very rare, and we report a case of highly symptomatic accelerated idioventricular rhythm (AIVR) originating from the RVAD that underwent intracardiac echocardiography (ICE) –guided catheter ablation with no...

Permanent junctional reciprocating tachycardia due to an atypical retrograde slow conducting decremental left posterolateral accessory pathway and tachycardia ‐induced cardiomyopathy in a pregnant adolescent
We report the challenging clinical course of a pregnant adolescent with PJRT due to an atypical retrograde slow conducting decremental left posterolateral AP. Pregnancy is known to exacerbate supraventricular arrhythmias and can lead to adverse maternal and fetal outcomes. To the best of our knowledge, there are no prior reports on the clinical course of rare incessant and difficult-to-treat arrhythmias such as PJRT in a pregnant adolescent patient.

Cardiac sarcoidosis with extensive and heterogeneous left ventricular FDG uptake in absence of guidelines indication for an implantable defibrillator: Ventricular tachycardia precipitated by immunosuppressive therapy, should we have done differently?
AbstractA 40-year-old man, newly diagnosed with cardiac sarcoidosis (CS) presented with symptomatic ventricular tachycardia three days after starting steroid-based immunosuppressive therapy (IT). There was no clear guideline indication for implantable cardioverter-defibrillator (ICD) before the initiation of IT. Shortly after ICD implantation and the initiation of anti-arrhythmic drugs, recurring ventricular arrhythmias required titration of the anti-arrhythmic drug therapy. One-year follow-up assessment showed no significant arrhythmias and complete PET scan FDG uptake suppression. This case, along with recent publication...

Long ‐term outcomes with abandoning versus extracting sterile leads: A 10‐year population‐based study
ConclusionAn initial lead abandonment strategy was associated with more complicated subsequent extraction procedures compared to patients with an initial transvenous lead extraction strategy. However, there was no difference in 10-year survival probability between both lead management approaches. (Source: Pacing and Clinical Electrophysiology : PACE)

Determination of sensed and paced atrial ‐ventricular delay in cardiac resynchronization therapy
ConclusionsA novel methodology for measuring electrical dyssynchrony was used to determine electrically optimal SAVD/PAVD during LV-only pacing. When BiV pacing, shorter AVDs produce better electrical synchrony. (Source: Pacing and Clinical Electrophysiology : PACE)
