Lesion formation following pulsed field ablation for pulmonary vein and posterior wall isolation
ConclusionPFA for AF resulted in durable and transmural atrial scar tissue at the PVs and PW. LGE CMR found a very homogeneous and contiguous lesion pattern with no signs for collateral damage. (Source: Pacing and Clinical Electrophysiology : PACE)

Survival, ventricular arrhythmia, and implantable cardioverter ‐defibrillator usefulness in toxic cardiomyopathy due to substance abuse
ConclusionVA are infrequent in the T-DCM population. The prophylactic ICD benefit was not observed in our cohort. The ideal timing for potential prophylactic ICD implantation in this population needs further studies. (Source: Pacing and Clinical Electrophysiology : PACE)

The specific value of upgrading to left bundle branch area pacing in patients with pacing ‐induced cardiomyopathy or non‐pacing‐induced cardiomyopathy related upgrade status: A retrospective study
ConclusionLBBaP upgrade effectively improved the cardiac function and clinical outcomes in PICM patients, but its effectiveness seemed to be limited as the deteriorated cardiac function cannot be completely reversed. For Non-PICMUS patients, the cardiac function and clinical outcomes Post-LBBaP had no significant improvement. (Source: Pacing and Clinical Electrophysiology : PACE)

Severe cardiac conduction disease associated with titin gene mutation
We report a 9-year-old female with history of leukodystrophy and family history of atrial fibrillation who presented with syncope and conduction abnormalities, including CHB. She underwent pacemaker implantation and genetic testing demonstrated a pathogenicTTN mutation likely responsible for her cardiac findings. Our case suggests an association betweenTTN mutations and conduction disease and emphasizes broadening gene testing in assessing these patients, especially when a family history is present.

Cardiac resynchronization therapy in adults with structural congenital heart disease and chronic heart failure
ConclusionCRT is efficacious in structural ACHD including in those who do not meet conventional criteria. Extrapolation of recommendations from adults with structurally normal hearts may be inappropriate. Future research should focus on improving patient selection for CRT, for example using techniques to better quantify mechanical dysynchrony and intra-procedural electrical activation mapping in these complex patients.

Optimizing conduction system pacing lead placement utilizing the image overlay technique

Validation of a handheld single ‐lead ECG algorithm for atrial fibrillation detection after coronary revascularization
ConclusionsThe automatic interpretation algorithm in a handheld thumb ECG device can rule out AF in patients recently undergoing coronary revascularization with high accuracy, but manual confirmation is needed to confirm the diagnose of AF because of high false positive rates.

Unusual atrial pacing induced by type II far ‐field p‐wave sensing in a patient with complete atrioventricular block
AbstractAn 88-year-old Japanese woman underwent DDD pacemaker (MicroPort KORA 250 DR, V lead: VEGA R52) implantation for complete atrioventricular block. A 12-lead electrocardiogram for a routine examination showed atrial pacing within the intrinsic P wave, followed by inhibition of ventricular pacing. Pacemaker interrogation revealed no abnormalities in the basic parameters; however, ventricular pacing was inhibited by far-field sensing of intrinsic atrial waves before atrial events; type II far-field P-wave sensing. As a result, unusual atrial pacing occurred due to the pause suppression algorithm, which is the one of th...

Predictors of pacemaker implantation within three months after catheter ablation of atrial fibrillation
ConclusionsOlder age, female sex, paroxysmal AF and repeated ablation were identified as predictive risk factors for PMI after RFCA in patients with AF. A "watch and wait" strategy could be taken for patients with temporary PMI after ablation, especially for those with prolonged sinus pause after AF termination.

Left atrial roof region ablation using a visually guided laser balloon
AbstractBalloon-based catheter ablation including visually guided laser balloon (VGLB) has been adopted a first line therapeutic strategy for the patients with atrial fibrillation (AF). Recently, the roof area ablation beyond pulmonary vein (PV) isolation (PVI) using cryoballoon has been described as an effective therapy for the patients with persistent AF. However, the roof area ablation performed with a VGLB remains unknown. In this case, we report the case of roof area ablation for the patient with persistent AF using a VGLB.

Percutaneous extraction of a Micra AV transcatheter pacing system due to a rare sudden battery failure after 19 months from implantation: A first experience worldwide
We describe a case of sudden battery malfunction of a Micra AV TPS, which required the extraction and the placement of a new pacing system in the right ventricle.DiscussionThis case, which has never been reported, highlights the need to a careful fluoroscopic evaluation and the usefulness of remote monitoring.
