Background-Vasovagal syncope (VVS) is the most common cause of recurrent syncope that can be debilitating despite optimal conventional therapy. The aim of this study was to evaluate the feasibility and efficacy of selective endocardial autonomic denervation in left atrium (LA) as an alternative treatment strategy in patients with highly symptomatic VVS. Methods and Results-Ten consecutive patients (mean age, 50.4Ϯ6.4 years; 7 women) with a medium of 3.5 (range, 2-20) recurrent episodes of VVS during the preceding year and positive head-up tilt testing in whom standard therapies were ineffective or poorly tolerated were enrolled. Ganglionated plexi (GP) in the LA, identified by high-frequency stimulation, was targeted by radiofrequency catheter ablation. The patients were then followed up at 3, 6, 12, 24, and 36 months, including repeated head-up tilt testing and Holter at 3 and 12 months. Radiofrequency energy was applied at the left superior GP in 10 patients, right anterior GP in 5, and left inferior GP in 3, using an 8-mm ablation catheter.

“…However, improved outcomes are reported for catheter ablation of PeAF guided by real-time dominant frequency analysis 2 and by dynamic 3-dimensional (3D) electroanatomic mapping,3, 4 particularly when this is used to target the origin and trajectory of rotors 5, 6. Here, we present a complete case study of a patient with PeAF who was treated successfully with stepwise linear ablation.…”

Background:The multielectrode array (MEA) enables noncontact mapping of cardiac arrhythmias; our experience is reviewed and reported. Hypothesis: The MEA has a role as first line therapy in multiple arrhythmias. Methods: Retrospective and prospective analysis of all consecutive cases performed using the MEA over a 6 year period. Results: Electrophysiological study and catheter ablation, 46% under general anaesthesia, using radiofrequency (RF), cryothermal and low energy direct current (DC) was performed in 66 procedures on 31 females and 29 males, average age 50.2 yrs (19.3-81.6); 8 patients underwent multiple procedures. 24 patients (36%) had undergone past ablation for the same arrhythmia. A wide variety of arrhythmias from all chambers were treated, majority right atrial (56%) and right ventricular (29%). Procedural success was complete in 77.4% and partial/indeterminate in 11.3%, highest in right atrial tachycardia, right ventricular outflow tract ectopy and typical atrial flutter (79, 82 and 100%). RF energy was most commonly used (67%) and DC carried 100% success. Ablation was delivered at 'early activation' and 'breakout' in focal arrhythmias. In re-entrant circuits linear ablation transectingpath of activation extending to regions of functional/anatomic block was performed. Two of 7 complications were attributed to the MEA: groin haematomas. At mean 12.4 mo follow up 56% were arrhythmia free, 15% asymptomatic or minimally symptomatic and 12 patients had new arrhythmias. Conclusions: The MEA is effective, safe and suitable for first line therapy in multiple cardiac arrhythmias particularly in the right heart. Further study is warranted comparing it to other mapping techniques.
