Article Synopsis
- The study explores a method for ablating persistent atrial fibrillation (AF) without using a circular mapping catheter (CMC), potentially lowering costs and reducing procedural duration.
- Over three years, 261 ablation procedures were conducted without CMC, showing no loss in safety or effectiveness.
- At the one-year mark, 72% of patients experienced no recurrence of AF or atrial flutter, suggesting this technique is viable and warrants further investigation into its benefits on procedure times.
Purpose: In this study, we evaluated the feasibility, efficacy, and safety of radiofrequency ablation of paroxysmal atrial fibrillation (AF) with the use of an ablation catheter only (non-CMC group) by retrospectively comparing its procedural success and recurrence rates at 1 year to ablation performed with the help of a circular mapping catheter (CMC group).
Methods: We compared the success and recurrence rates between 226 patients and 251 patients who underwent index ablation with and without the use of CMC, respectively.
Results: Freedom from recurrence was defined as a 1-year absence of AF/atrial tachycardia (AT) episodes > 30 s, beyond the 3-month blanking period.
Article Synopsis
- The study examines the effectiveness of using a 3D navigation system during cavo-tricuspid isthmus (CTI) ablation for treating typical atrial flutter (AFL), comparing it to traditional fluoroscopy methods.
- Results showed that 3D navigation significantly reduced fluoroscopy time and radiation exposure while maintaining similar success rates, procedural times, and safety between the two methods.
- The authors recommend broadening the use of 3D navigation systems for CTI ablation due to these improved outcomes.
New insights into the clinical signs of supraventricular tachycardia: The "sign of lace-tying".
Ann Noninvasive Electrocardiol

Background: Supraventricular tachycardias (SVT) are a common arrhythmia therefore an accurate diagnosis is of clinical importance. Although an ECG performed during tachycardia greatly aids diagnosis, patient history and predisposing factors also improve diagnostic accuracy.
Methods: This prospective study included 100 consecutive patients undergoing electrophysiological study for SVT with the aim to reassess their clinical characteristics and describe frequent predisposing factors, such as the "sign of lace-tying" that to our knowledge has not previously been reported.
Introduction: Radiofrequency isolation of pulmonary vein can be accompanied by transient sinus bradycardia or atrioventricular nodal (AVN) block, suggesting an influence on vagal cardiac innervation. However, the importance of the atrial fat pads in relation with the vagal innervation of AVN in humans remains largely unknown. The aim of this study was to evaluate the role of ganglionated plexi (GP) in the innervation of the AVN by the right vagus nerve.
