Mechanical Circulatory Support During Ventricular Tachycardia Ablation: A Systematic Review and Meta‐Analysis of Procedural and Clinical Outcomes

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Catheter ablation is an established therapy for ventricular tachycardia (VT); however, hemodynamic instability frequently limits procedural mapping and success. Temporary mechanical circulatory support (tMCS) devices are increasingly used to maintain end‐organ perfusion during VT ablation, yet their impact on clinical outcomes remains ...

Clinical Utility of Tissue Proximity Indication With a Variable‐Loop Circular Catheter for Pulmonary Vein Isolation

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background The variable‐loop circular catheter (VLCC, VARIPULSE) is a pulsed‐field ablation (PFA) catheter equipped with a Tissue Proximity Indication (TPI) function, which monitors catheter‐tissue contact. Although TPI‐negative sites have been reported to contribute to gap formation, no studies have evaluated the utility of real‐time function.

A Simplified Epicardial Ablation Strategy for Ventricular Tachycardia Integrating CT‐Derived Epicardial Adipose Tissue Into Three‐Dimensional Electroanatomic Mapping

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Introduction Epicardial adipose tissue (EAT) can attenuate electrograms and limit lesion formation during epicardial ventricular tachycardia (VT) ablation. Case Presentation We developed a simplified workflow using predefined CT attenuation values to integrate EAT into the CARTO 3 system. We applied this approach in three patients with dilated

Impact of Left Bundle Branch Pacing on Left Ventricular Mechanical Efficiency

Journal of Cardiovascular Electrophysiology, EarlyView.
The analysis of myocardial work in 115 consecutive patients receiving left bundle branch area pacing revealed a strong correlation between all myocardial work indices recorded during spontaneous or paced rhythm. Conversely, no significant correlations were observed between myocardial work indices and the R wave peak time in V6 or the V6–V1 interpeak ...

Invasive Assessment of Right Ventricular Dysfunction Predicts Periprocedural Outcomes in Patients Undergoing Unplanned Ventricular Tachycardia Ablation

Journal of Cardiovascular Electrophysiology, EarlyView.
Displays bar graphs showing outcome rates stratified by clinical and hemodynamic variables. Asterisks (*) denote statistically significant differences (p ≤ 0.05). “NS” indicates non‐significant comparisons. Percentages are shown above each bar. The top panel corresponds to acute kidney injury (blue bars), and the bottom panel corresponds to acute ...

Impacts of Hemodynamic Support on Ventricular Arrhythmia Ablation

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Data on the efficacy of hemodynamic support (HS) for protecting ventricular arrhythmia (VA) ablation in high‐risk heart failure (HF) patients with an impaired left ventricular function and its impact on mortality is limited. Objectives This study aimed to assess procedural efficacy, related complications, VA‐free survival, and ...

In Vitro Assessment of 3T MRI Effects on Non–3T‐Compatible Cardiac Implantable Electronic Devices

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background The safety of cardiac implantable electronic devices (CIEDs) during 3‐Tesla (3T) MRI remains uncertain, particularly for devices not designed for 3T use. We experimentally evaluated 3T MRI effects on 3T‐compatible and non–3T‐compatible CIEDs.

Electrophysiologic Assessment of the Successful Left Bundle Branch Pacing Using the Standardized Criteria

Journal of Cardiovascular Electrophysiology, EarlyView.
The left bundle branch anatomy graphic was created using AI‐assisted medical illustration. ABSTRACT Introduction Left bundle branch area pacing (LBBAP) is an emerging physiological pacing method that preserves ventricular synchrony. Achieving true LBB capture remains challenging, and the reported success rates vary considerably due to nonuniform ...

Comparison of Spatio‐Temporal Dispersion Electrogram Ablation and Low Voltage Zone Ablation in Patients With Persistent Atrial Fibrillation

Journal of Cardiovascular Electrophysiology, EarlyView.
This study compared STDE‐guided versus LVZ‐guided ablation beyond PVI in 107 persistent AF patients. At 24 months, the AF‐free survival rate was significantly higher in the STDE group (76.3% vs. 58.4%, p=0.027). STDE ablation independently reduced recurrence risk (HR: 0.29, p=0.004), providing superior clinical efficacy over LVZ ablation.

Impact of Carina Width on Re‐Ablation Rate of Atrial Fibrillation After Primary Cryoballoon‐Ablation

Journal of Cardiovascular Electrophysiology, EarlyView.
Right side carina width is associated with the incidence of reconnection of RPVs and re‐ablation. Increased left side carina width was associated with re‐ablation rate, but there was no association with reconnection of the LPVs. ABSTRACT Background Reconnection of the pulmonary veins (PVs) is the primary cause of atrial fibrillation (AF) episodes after
