Minimalistic strategy for coronary sinus lead implant: A single tool capable of electrophysiological mapping, pressure measurement and angiography
ConclusionIn proof of concept paper, we describe a technique of LV lead implantation potentially without the use of contrast and standard CS guiding catheters. Once familiar, this approach may provide a less complicated strategy.This article is protected by copyright. All rights reserved (Source: Pacing and Clinical Electrophysiology : PACE)

Telethonin variants found in Brugada syndrome, J ‐wave pattern ECG, and ARVC reduce peak Nav1.5 currents in HEK‐293 cells
ConclusionsWe found twoTCAP variants in the patients with BrS, J ‐wave pattern ECG, and ARVC that can cause loss‐of‐function of the hNav1.5 in heterologous expression systems. Our observation suggests that these variants might impair INa and be associated with the patients ’ electrophysiological phenotypes. Further studies linking our experimental data to clinical phenotypes are warranted. (Source: Pacing and Clinical Electrophysiology : PACE)

Physical activity and atrial tachyarrhythmia recurrence in atrial fibrillation patients after catheter ablation
AbstractBackgroundThe association between physical activity (PA) and atrial tachyarrhythmia (AT) recurrence after ablation for atrial fibrillation (AF) remains unclear.MethodsWe consecutively enrolled 496 patients treated with AF ablation therapy in Beijing Anzhen Hospital. After excluding 6 patients with valvular heart disease, 7 patients with congenital heart disease, 33 patients lost to follow ‐up, and 14 patients who did not provide PA level during follow‐ups, 436 patients had their PA level assessed by the International Physical Activity Questionnaire‐Short Form before ablation and each time of follow‐up.

Value of Defibrillation Threshold Testing in Children with Non ‐Transvenous Implantable Cardioverter Defibrillators – Are routine DFT tests indicated?
ConclusionA significant number of NT ‐ICD failures was detected by serial DFT testing. Serial DFT testing was safe in pediatric patients with a NT‐ICD as all induced arrhythmia could be terminated. Prediction of DFT with non‐invasive markers remains difficult and might help to schedule intervals for routine DFT tests to avoid unn ecessary tests.This article is protected by copyright.

CRT in a congenital heart disease patient with interventricular dyssynchrony due to an RV conduction delay
AbstractWe encountered a unique pattern of cardiac dyssynchrony in a patient with complex congenital heart disease (heterotaxy syndrome) with a biventricular physiology and systemic left ventricle (LV). On speckle tracking echocardiography, dyssynchrony was not detected within the LV, but was noted in an interventricular fashion between the LV and right ventricle (RV). An electrophysiologic study revealed a conduction delay in the subpulmonary RV. Cardiac resynchronization therapy provided reverse cardiac remodeling and an excellent result in our patient by placing the pacing leads around the dyssynchronous lesion. (Source...

We report a case of a 42 ‐year‐old lady with idiopathic restrictive cardiomyopathy, persistent atrial fibrillation status post pulmonary vein isolation, and premature ventricular complex ablation with a systolic dysfunction, who presented with incessant slow narrow complex tachycardia of 110 bpm that appeared to be an AVNRT. Her baseline EKG revealed a first‐degree AV block with a PR of 320 ms. EP study showed no evidence of anterograde fast pathway conduction. Given this fact, the decision was to attempt an ablation of the retrograde fast pathway. The fast pathway was mapped during tachycardia to its usual...

High mean entropy calculated from cardiac MRI texture analysis is associated with antitachycardia pacing failure
ConclusionsOur findings suggest lower scar heterogeneity (mean entropy) is associated with successful ATP, whereas higher scar heterogeneity is associated with more aggressive VAs unresponsive to ATP requiring shock therapy that may be due to inability of the paced wavefront to propagate through scar and terminate the VA circuit.

High ‐density mapping‐guided corrective HIS bundle pacing after failed CRT upgrade for persistent left superior vena cava
We present a complex case with successful, high ‐density electroanatomic mapping (EAM) guided corrective His bundle pacing (CHBP) following failed CRT upgrade in a patient with PLSVC, congenital heart disease, and pacing‐associated heart failure. CHBP restored physiological conduction in left bundle branch block with complete conduction block leading to clinical improvement and cardiac remodeling. The presented case supports the growing evidence that EAM‐guided CHBP may be considered a feasible alternative to conventional CRT when venous anatomy is not favorable for left ventricular lead implantation.
