Catheter ablation for tachyarrhythmia via superior approach has been used in patients without possible inferior vena cava access such as in cases of venous occlusion or complex anomaly. Difficulty in catheter manipulation, instability, number of required vascular access, and radiation exposure of operator had been described in the procedure. Application of three-dimensional (3-D) mapping system in catheter ablation via superior approach could navigate the guiding catheter and provide more precise ablation.

- - The study investigated the relationship between the distance from the descending aorta to the left inferior pulmonary vein (Dao-LIPV) and the presence of triggers and drivers in atrial fibrillation (AF) during ablation procedures.
- - A total of 886 patients with drug-refractory AF were analyzed; 63 were found to have LIPV triggers or drivers, with Dao-LIPV distance proving to be a strong predictor for these occurrences.
- - The research developed a risk score model indicating that patients with a Dao-LIPV distance of 2.5 mm or less and persistent AF have a significantly higher risk of LIPV triggers or drivers, which can help electrophysiologists plan ablation treatments more effectively.*
Background: Modifying the autonomic system after catheter ablation may prevent the recurrence of atrial fibrillation (AF). Evaluation of skin sympathetic nerve activity (SKNA) is a noninvasive method for the assessment of sympathetic activity. However, there are few studies on the effects of different energy settings on SKNA.

- The study investigates changes in skin sympathetic nerve activity (SKNA) in patients undergoing catheter ablation for idiopathic ventricular arrhythmia (VA).
- Researchers monitored 43 patients' SKNA before and after the ablation procedure to assess neuromodulation effects.
- Results showed that patients whose ablation was successful had lower post-ablation SKNA compared to those with failed procedures, particularly those whose arrhythmias involved the right ventricular outflow tract (RVOT).
