Article Synopsis
- The study focuses on distinguishing near-field (NF) and far-field (FF) electrograms (EGMs) to better identify critical areas for treating ventricular tachycardia (VT) during ablation procedures, using a new algorithm for EGM analysis.
- A multicenter study involving 30 patients was conducted, analyzing a massive dataset of EGMs to compare peak frequencies (PF) in different heart rhythms, revealing significant differences that could aid in pinpointing problematic heart circuits.
- Results indicated that a low-voltage area PF threshold of ≥200 Hz is effective for identifying VT isthmus, with findings suggesting that chronic amiodarone treatment can lower these PF values, potentially impacting treatment outcomes.
Article Synopsis
- - The study evaluated the effectiveness of two PVC ablation techniques: multipolar mapping using a high-density catheter and point-by-point mapping with the ablation catheter, involving 698 patients across 10 hospitals from 2017 to 2021.
- - Results revealed that the multipolar group had significantly better mapping efficiency (more activation points) and shorter procedure times, while both groups showed high acute success rates and midterm efficacy.
- - Notably, patients undergoing left-sided PVC ablation had better midterm outcomes with the multipolar method, suggesting it may lead to more successful results in certain cases.
Background: Epicardial ablation complications are more frequent in patients with preexisting pericardial adhesions. As opposed to the dry puncture technique, the coronary vein exit and carbon dioxide (CO) insufflation (EpiCO) technique allows diagnosing pericardial adhesions before subxiphoid puncture.
Objective: This study aimed to evaluate the efficacy of the EpiCO technique in diagnosing pericardial adhesions prior to subxiphoid puncture.
