Electrocardiographic morphology during left bundle branch area pacing: Characteristics, underlying mechanisms, and clinical implications.
In this study, we investigated the characteristics and underlying mechanisms of the electrocardiographic (ECG) morphology during left bundle branch area pacing (LBBAP), which have not been systematically described. ⋯ LBBAP-ECG patterns are characterized by a shorter terminal R' wave duration in lead V1 compared with that of native RBBB configurations. Bundle branch conduction integrity has an impact on ECG characteristics during LBBAP.

Case ReportsFirst-in-man fully leadless transvenous CRT-P with a transseptal implant of WISE-CRT® system and Micra® PM.
We describe the world's first fully leadless cardiac resynchronization therapy pacing implant with transseptal approach, in a patient with pacemaker dependency, atrial fibrillation, ischemic hypokinetic cardiomyopathy, and a history of pocket infections. After lead extraction, we implanted a MicraTranscathether Pacing System® (Medtronic, Minneapolis, MN, USA) as the sole right ventricular pacemaker, and the WISECRT system (EBR Systems, Sunnyvale, CA, USA) to provide biventricular pacing. We performed the WISECRT implant procedure using the transseptal approach given the presence of a prosthetic aortic mechanical valve, achieving satisfactory periprocedural results.

Multicenter StudyIncreased risk of hematoma with uninterrupted warfarin in patients undergoing implantation of subcutaneous implantable cardioverter defibrillator.
The perioperative management of anticoagulation with the use of subcutaneous implantable cardioverter-defibrillator (S-ICD) implantation is still evolving. ⋯ The uninterrupted use of warfarin in the perioperative period of S-ICD implantation is associated with an increased risk of lateral pocket hematoma.

Link between Brugada phenocopy and myocardial ischemia: Results from the International Registry on Brugada Phenocopy.
Brugada phenocopies clinical entities that have indistinguishable electrocardiographic (ECG) patterns from true congenital Brugada syndrome. However, they are induced by other clinical circumstances such as myocardial ischemia. The purpose of our study was to examine the clinical features and pathogenesis of ischemia-induced Brugada phenocopy (BrP). ⋯ Myocardial ischemia is a commonly reported etiology of BrP. Importantly, this study found no association between BrP induced by myocardial ischemia and sudden cardiac death or malignant ventricular arrhythmias.

Meta AnalysisProphylactic pulmonary vein isolation during cavotricuspid isthmus ablation for atrial flutter: A meta-analysis.
Atrial arrhythmias (AA), including atrial fibrillation (AF), have been reported in patients after cavotricuspid isthmus (CTI) ablation for typical atrial flutter (AFL). Several studies have examined the effect of performing concomitant pulmonary vein isolation (PVI) with CTI on recurrent AA. These studies were analyzed to determine the overall effect of this approach on recurrent AA. ⋯ This meta-analysis shows addition of a prophylactic PVI during CTI ablation significantly reduces recurrent AA at 1 year without significantly increasing major complications.
