Chronic inflammation harbors a vulnerable substrate for atrial fibrillation (AF) recurrence after catheter ablation. However, whether the ABO blood types are associated with AF recurrence after catheter ablation is unknown. A total of 2106 AF patients (1552 men, 554 women) who underwent catheter ablation were enrolled retrospectively.

We aimed to investigate the isochronal late activation mapping to access the abnormal conduction velocity for predicting AF ablation outcome.
Methods: Forty-five paroxysmal AF patients (30 males, 57.
Article Synopsis
- Atypical atrial flutter (aAFL) is common after cardiac surgeries or procedures for atrial fibrillation, and this study aimed to improve ablation techniques using a new mapping algorithm.
- Researchers studied 15 patients with 20 cases of aAFL, finding that the ablation sites identified by analyzing global activation histograms (GAH) were highly effective in targeting reentry circuits.
- The use of the Lumipoint algorithm facilitated better identification of slow conduction areas, leading to quicker aAFL termination and improved patient outcomes.
Background: The comprehensive surveillance for interval changes in signal-averaged P-wave (SAPW) after pulmonary vein isolation (PVI) remains lacking. We aimed to analyze the SAPW parameters before and after PVI and explored their link to the left atrial electrical properties.
Methods: Eighteen patients with paroxysmal atrial fibrillation receiving primary catheter ablation were enrolled.
Background: The identification of post pulmonary vein isolation (PVI) gaps by activation and voltage maps is time-consuming. This study aimed to investigate the characteristics, efficiency and accuracy of LiveView dynamic display module (EnSite™ Dynamic Display; Abbott, Abbott Park, IL, USA) in unmasking post PVI gaps and conduction block line.
Method: Twenty four patients with paroxysmal atrial fibrillation (PAF) who failed to achieve first-pass PVI or with recurrent PAF were enrolled.
Long QT syndrome (LQTS) is commonly presented with life-threatening ventricular arrhythmias (VA). Renal artery denervation (RDN) is an alternative antiadrenergic treatment that attenuates sympathetic activity. We aimed to evaluate the efficacy of RDN on preventing VAs in LQTS rabbits induced by drugs.
