Summary: Recurrent atrial tachycardia is a common phenomenon after catheter ablation for AF, with gap-related macro re-entrant atrial tachycardia being the dominant mechanism. The optimal ablation strategy and procedural endpoint for multiple inducible ATs after ablation of the clinical AT are still unclear, but ensuring durable linear block and PV isolation may be sufficient for preventing further AT.

Summary: The study found that HPSD-AFCA significantly reduced procedure time compared to ConvP-AFCA, with no significant difference in complication rate and 3-month HRV. At one-year follow-up, rhythm outcomes were similar between the two groups. These results suggest that HPSD-AFCA has similar efficacy, safety, and influence on autonomic function as ConvP-AFCA.

Summary: A systematic review and pooled analysis of randomized control trials showed that catheter ablation of atrial fibrillation is associated with low rates of procedure-related complications and mortality, which have declined over the past decade.

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: A 63-year-old healthy male with atrial fibrillation presents with symptoms of dyspnea and irregular heartbeat. Physical examination reveals high blood pressure, irregular pulse, and ECG confirms atrial fibrillation. Further evaluation and treatment plan are needed.

Summary: This article reviews and compares the rationale and evidence supporting high-power, short-duration radiofrequency (RF) ablation with conventional-power, conventional-duration RF ablation for atrial fibrillation (AF). Both approaches are similarly safe and effective for AF ablation, with theoretical advantages of high-power, short-duration ablation including greater procedure efficiency and limited conductive heating of collateral structures, but must be weighed against the narrower safety margin related to rapid energy delivery.

Summary: The study compared outcomes of septal myectomy with and without the Cox-maze IV procedure in patients with hypertrophic obstructive cardiomyopathy and atrial fibrillation. Results showed that patients who underwent the Cox-maze IV procedure had better mid-term survival and reduced mid-term atrial fibrillation recurrence, indicating its potential to lower recurrence rates in patients with atrial fibrillation.

Summary: Andrade et al. found that initial catheter cryoballoon ablation strategy resulted in lower incidence of persistent atrial fibrillation and lower arrhythmia burden compared to antiarrhythmic drug therapy in patients with paroxysmal atrial fibrillation during 3 years of follow-up. The study builds upon the findings of the EARLY-AF trial and the STOP AF First trial. Due to the relatively small sample size (303 patients) and short follow-up period, it may be difficult to detect mortality benefits of cryoballoon ablation.

Summary: This study aimed to investigate the safety of high-power short duration radiofrequency ablation for atrial fibrillation, with a focus on oesophageal lesions. The results showed a 6% incidence of thermal oesophageal injury, with a low risk of perforating complications. Factors such as total ablation time, history of stroke, and body mass index were associated with the incidence of oesophageal injury.

Summary: This study aimed to measure the effects of two different esophageal protection strategies on procedure time and variability in procedure time during radiofrequency pulmonary vein isolation (PVI). The results showed that active esophageal cooling during PVI is associated with reduced procedure time and reduced variation in procedure time.

Summary: This study evaluated the use of a visualizable steerable sheath compared with a non-visualizable steerable sheath for catheter ablation of atrial fibrillation (AF). The results showed that the visualizable sheath significantly reduced fluoroscopy time, dose, and dose area product, but increased mapping time without affecting the overall procedure time.

Summary: This study found a linear and positive association between P wave duration within 72 hours after radiofrequency ablation and the risk of atrial fibrillation recurrence in patients with early persistent atrial fibrillation. This association was consistent across different subgroups and there was no significant interaction.

Summary: This study compared the outcomes of aortic valve replacement with and without the Cox-maze IV procedure in patients with calcific aortic valvular disease and atrial fibrillation. The results showed that the Cox-maze group had better mid-term survival and lower mid-term atrial fibrillation recurrence compared to the no Cox-maze group.

Summary: In this systematic review, pulsed field ablation (PFA) was found to have a high success rate and low major adverse events in the treatment of atrial fibrillation, leading to a decreased recurrence of atrial arrhythmia compared to thermal ablation. However, further randomized controlled trials are needed to validate the efficacy and safety of PFA.

Summary: This meta-analysis compared the effectiveness of zero fluoroscopy (ZF) and non-zero fluoroscopy (NZF) strategies for atrial fibrillation (AF) ablation procedures. The ZF approach significantly reduced procedure time, fluoroscopy time, and fluoroscopy dose without compromising acute and long-term success rates or complication rates.
