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.

Variable morphologies of preexcitation due to a concomitant Brugada pattern.

Since the first publication of the Brugada syndrome in 1992 several variants of this ECG pattern have been described. We report a very unusual case of preexcitation with changing electrocardiographic morphologies which appeared to be an association of a variable Brugada pattern with a persistent antegrade preexcitation.

Pneumothorax is a rare complication of pacemaker lead insertion by subclavian way. We report a case of temporary ineffective biventricular pacing due to pneumothorax. This complication has to be ruled out before electing to reposition or to replace the lead.
