ConclusionIntra-Hisian block is a condition that is often associated with delayed or blocked electrical conduction within the His bundle. When symptomatic, patients often present with syncope or presyncope. Etiologies of this condition include degenerative changes, myocardial infarction, autoimmune disorders, infections, medications, and more. This case emphasizes the importance of electrophysiology studies (EPS) in the diagnosis and management of patients with intra-Hisian block. Prompt intervention, such as the placement of a dual-chamber pacemaker, can alleviate symptoms and improve patient outcomes. Thus, clinical awar...

Tricuspid regurgitation and infective endocarditis as a cause of lead dislodgement in left bundle branch area pacing
ConclusionsWe concluded that severe preoperative tricuspid regurgitation may cause lead dislodgement, and infective endocarditis may be a facilitator or main reason of lead dislodgement in cases of LBBAP. (Source: Pacing and Clinical Electrophysiology : PACE)

Ivabradine as a treatment option for junctional ectopic tachycardia in an adult female
AbstractA Junctional ectopic tachycardia diagnosis was performed using two electrophysiological maneuvers in an adult female with a narrow-complex supraventricular tachycardia with a bystander AV-node slow pathway conduction, who previously underwent catheter ablation attempts for an atrio-ventricular nodal re-entrant tachycardia misdiagnosis. The first maneuver was atrial entrainment with an atrial-His-His-atrial response. The second was based on the response to a premature atrial complex delivered at different phases of the tachycardia cycle confirming that anterograde slow pathway conduction and retrograde fast pathway ...

Sex ‐based differences in cardiac resynchronization therapy upgrade and outcome for patients with pacemaker and new‐onset heart failure
ConclusionWomen with pacemaker due to AV block are older but have less comorbidities than men. They are less likely to develop new-onset heart failure, but also less likely to receive a CRT upgrade if they do develop heart failure. Increased awareness of the positive effects of CRT upgrade and potential sex- and age-based discrimination is warranted. (Source: Pacing and Clinical Electrophysiology : PACE)

The influence of electrode ‐tissue‐coverage on RF lesion formation and local impedance: Insights from an ex vivo model
ConclusionsETC is a main determinant of lesion size and occurrence of steam pops. Baseline LI and LI-drop are useful surrogate parameters for real-time assessment of ETC and ΔLI correlates strongly with lesion size. (Source: Pacing and Clinical Electrophysiology : PACE)

Validation of a clinical model for predicting left versus right ventricular outflow tract origin of idiopathic ventricular arrhythmias
ConclusionThe published clinical score yielded a lower sensitivity and specificity in our cohort. However, for PVCs with R/S transition at V3, the combination with an existing ECG algorithm can improve the predictability of LVOT origin. (Source: Pacing and Clinical Electrophysiology : PACE)

Left ventricular endocardial activation maps during right ventricular pacing in pediatric patients
ConclusionsIn pediatric patients LVEA maps during RV pacing showed that the shortest LVAT was obtained with PHP. The LV activation pattern seemed similar in sinus rhythm, PHP and MSP, from midseptum to LV lateral base. (Source: Pacing and Clinical Electrophysiology : PACE)

Device implantation complicated by a retrosternal goiter
We report a case where the failure of the initial implantation of a primary CIED led to an unusual implantation route without goiter excision. The patient had an indication for cardiac resynchronization therapy (CRT) given his left ventricular (LV) function was impaired and had second-degree heart block Mobitz Type II; however, he had occluded bilateral subclavian veins due to a sizeable retrosternal goiter. This obstruction led to the implantation of a single lead pacemaker via the right femoral vein after multiple failed attempts at CRT, dual chamber pacemaker and left bundle branch area pacing (LBBaP).

Left ventricular CRT ‐D lead implantation using the retrograde approach following lateral vein balloon angioplasty
AbstractA 60-year-old female with heart failure with reduced left ventricle ejection fraction, implantable cardiac defibrillator and left bundle branch block was admitted to Department of Cardiology for cardiac resynchronization therapy defibrillator upgrade. Due to difficulties with advancement of left ventricular lead to lateral coronary vein, balloon angioplasty with use of retrograde approach via collateral branches and two CS sheaths positioning was performed. Final position of lead in lateral vein was achieved resulting with pacing threshold of 0.7 V/0.5 ms, impedance of 720 Ω and QRS of 130 ms. (Source: Pacing...

Challenges of atrial fibrillation and atrial flutter ablation in patients with pectus excavatum
AbstractAtrial fibrillation (AF) may be associated with chest wall abnormalities such as pectus excavatum (PE). Pulmonary vein isolation (PVI) has proven to be a useful strategy for radiofrequency catheter ablation (RFCA) of AF. However, the presence of chest wall abnormalities, such as pectus excavatum, imposes certain challenges during ablation due to the anatomic distortion that it causes. We highlight these challenges during ablation in this three-patient case series. (Source: Pacing and Clinical Electrophysiology : PACE)

Septal scar as a barrier to left bundle branch area pacing
ConclusionsThe presence of septal scar appears to make it more challenging to deploy a lead to the left ventricular septum via the transeptal route. Additional implant tools or alternative approaches may be required in patients with extensive septal scar. (Source: Pacing and Clinical Electrophysiology : PACE)

Atrial fibrillation catheter ablation associated silent cerebral emboli: A narrative review
AbstractThe incidence of silent cerebral emboli (SCE) associated with atrial fibrillation catheter ablation (AFCA) is much higher than that of stroke/transient ischemic attack (TIA). Interventional electrophysiologists have been increasingly alerted to asymptomatic cerebral infarction over the years. Plentiful studies revealed that diagnostic definitions, detection modalities, energy sources, ablation strategies, perioperative anticoagulation regimens, and patient-related factors were associated with the risk of AFCA-associated SCE. Studies related to non-interventional procedures found that SCE may prompt stroke, cognitiv...

Atrial paced rhythm and heart rate ‐dependent worsening of left atrial and ventricular function
ConclusionsIn patients with atrial paced rhythm, the increase in HR could be associated with worsening of LA and LV functions, as assessed by two-dimensional speckle tracking analyses. These results offer new data on HR-related atrioventricular function and could be useful for guiding the optimal HR responsiveness of the implanted devices.

Chinese expert consensus on the construction of the fluoroless cardiac electrophysiology laboratory and related techniques
AbstractTranscatheter radiofrequency ablation has been widely introduced for the treatment of tachyarrhythmias. The demand for catheter ablation continues to grow rapidly as the level of recommendation for catheter ablation. Traditional catheter ablation is performed under the guidance of X-rays. X-rays can help display the heart contour and catheter position, but the radiobiological effects caused by ionizing radiation and the occupational injuries worn caused by medical staff wearing heavy protective equipment cannot be ignored. Three-dimensional mapping system and intracardiac echocardiography can provide detailed anato...
