Summary: This study aimed to investigate the treatment effect of combining PVI with 6 short ablation lines on paroxysmal AF patients. The results showed that the proportion of patients with freedom from atrial tachyarrhythmia was significantly higher in the PVI+6L group compared to the PVI group, and the mean AF burden was reduced, but the procedural and ablation times were slightly longer, and the X-ray exposure was similar between the two groups. Therefore, adding 6 short ablation lines on the PVI circumferences can effectively reduce the AF recurrence rate.

Summary: For patients undergoing radiofrequency pulmonary vein isolation, the necessity of pulmonary vein angiography was investigated after the use of high-resolution mapping catheters and high-power, short-duration ablation technique. The study found that omitting pulmonary vein angiography had no significant impact on the efficacy, efficiency, and complications of the ablation procedure. Therefore, avoiding pulmonary vein angiography may be useful, especially for young patients and those with chronic renal disease, when using this protocol.

Summary: In this study, extra-atrial injuries after pulmonary vein isolation (PVI) using pulsed field ablation (PFA) and thermal ablation methods were compared in 41 patients with paroxysmal atrial fibrillation (AF). It was found that PFA did not induce any signs of esophageal injury on cardiac magnetic resonance (CMR) imaging after PVI, indicating a potential improvement in safety for catheter ablation of AF.

Summary: This study analyzed the impact of different ablation strategies on patients with recurrent atrial fibrillation (AF) despite durable pulmonary vein isolation (PVI). The results showed that no ablation strategy, whether used alone or in combination, appeared to be superior in improving arrhythmia-free survival. Left atrial dilatation was found to be a significant predictor of ablation outcome in this population.

Summary: This study investigated the 10-year outcomes of radiofrequency catheter ablation (RFCA) in patients with non-paroxysmal atrial fibrillation (AF). It was found that single RFCA procedure had unsatisfactory results, and multiple procedures were required for adequate rhythm control. Enlarged left atrium, presence of non-pulmonary vein triggers, and undergoing complex fractionated atrial electrogram (CFAE) ablation were independent predictors for recurrent atrial tachyarrhythmia after a single procedure.

Summary: The recent study showed that catheter ablation did not benefit patients with AF, HF, and severely reduced LVEF. However, it was found that RFCA could improve outcomes in HF patients with AF and impaired LVEF. The RFCA group had lower mortality, HF hospitalization, and AF recurrence rates, as well as improved LVEF and quality of life.

Summary: This study retrospectively compared the efficacy of catheter ablation (CA) with medical therapy (MT) in atrial fibrillation (AF) patients with mildly reduced or mid-range ejection fraction (HFmrEF). The results showed that CA was associated with reduced HF hospitalization and all-cause mortality compared to MT. Additionally, CA led to significant improvements in left ventricular ejection fraction (LVEF) and decreased left atrium (LA) diameter. It is suggested that early rhythm control with CA should be considered in AF patients with HFmrEF.

Summary: This study aimed to evaluate the abnormal conduction velocity using isochronal late activation mapping and predict the recurrence of atrial fibrillation (AF) after pulmonary vein isolation. The presence of deceleration zone was associated with higher risk of AF recurrence. Therefore, isochronal late activation mapping is of great importance in predicting the outcome of AF ablation in patients with paroxysmal AF.

Summary: Real-time simultaneous amplitude frequency electrogram transform (SAFE-T) can be used to identify and characterize the drivers of nonparoxysmal atrial fibrillation (NP AF) during sinus rhythm (SR). The study found that termination sites during AF exhibited high similarity index (SI) and high SAFE-T values during SR, indicating the presence of high frequency components. This suggests that SAFE-T mapping is a feasible method for identifying and characterizing AF drivers.

Summary: This study aimed to investigate the risk factors for left ventricular (LV) cardiomyopathy and the outcomes of patients with ventricular arrhythmia (VA) originating from the LV summit (LVS). The results showed that QRS duration (QRSd) and absolute earliest activation time discrepancy (AEAD) were independent factors associated with deteriorating LV systolic function in patients with VA, and catheter ablation could reverse LV remodeling. Narrower QRSd and better LV ejection fraction (LVEF) were associated with better recovery of LV function after ablation.

Summary: This study aimed to evaluate the predictive value of heart rate variability (HRV) on all-cause mortality in end-stage kidney disease (ESKD) patients. The study found that post-dialysis HRV parameters were able to predict the risk of all-cause mortality, while pre-dialysis and during dialysis HRV parameters were not able to predict mortality risk. Specifically, higher very low frequency (VLF), normalized low frequency (nLF), and LF/HF ratio were associated with lower risk of all-cause mortality, while higher normalized high frequency (nHF) was associated with increased mortality risk.

Summary: This study investigated influenza vaccination coverage, knowledge level, and related factors in patients with diabetes mellitus (DM) or ischemic heart disease (IHD) in a tertiary hospital in northern Thailand. Of the 150 patients interviewed, 45.3% received influenza vaccination. Knowledge level did not differ between vaccinated and non-vaccinated individuals. Multivariable logistic regression analysis revealed that knowing their right to receive free vaccinations and perceiving a need for vaccination were significantly associated with receiving the influenza vaccine. Overall, vaccination coverage was low, but knowledge level was high in these patients. Factors such as awareness of entitlement and perceived need should be considered to promote influenza vaccination in patients with DM and IHD.

Summary: This study aimed to investigate the differences in nonlinear heart rate variability (HRV) between patients with and without recurrence before and after pulmonary vein isolation (PVI) for paroxysmal atrial fibrillation (PAF). The results showed that the non-recurrence group had significant decreases in the high-frequency component (HF), root mean square of successive RR interval differences (RMSSD), and Poincare Plot index SD1 1-3 months after PVI, and an increase in DFA(slope2) 6-12 months after PVI. The non-recurrence group also had significant decreases in the LF/HF ratio and DFA(slope1) 1-3 and 6-12 months after PVI, while no significant changes were observed in the recurrence group. These findings suggest that changes in vagal tone, long-term fractal complexity, and sympathetic tone as well as short-term fractal complexity play crucial roles in AF recurrence following PVI.

Summary: This study aims to investigate the electrophysiological characteristics and clinical implications of the critical isthmus (CI) for the maintenance of scar-related reentrant atrial tachycardias (ATs) during sinus rhythm (SR), and to map the functional substrate of the CI during SR. The results showed that the CI regions during SR were characterized by low voltage, conduction slowing, and fractionated electrogram. Targeting these regions achieved a high rate of termination or change of the reentrant circuit.
