Introduction: Accelerated cardiac sympathetic activity has been implicated in the development of atrial fibrillation. Ablation or excision of atrial epicardial ganglia for the treatment of atrial fibrillation has been reported. However, visualization of the atrial neural network is considered difficult. We attempted to image the sympathetic innervation with 123 I-metaiodobenzylguanidine (MIBG) using a novel solid-state whole-body scanner (VERITON). Methods: We performed pulmonary vein isolation using a cryoballoon in 10 patients with paroxysmal atrial fibrillation. MIBG images using specific processing were evaluated before and 3 months after ablation to evaluate the neural network of the left peri-atrial cardiac sympathetic activity and its response to ablation. Discrete epicardial accumulation of MIBG was identified using MIBG images fused with atrial computed tomography images. We quantitatively calculated the discrete MIBG accumulation in each pulmonary vein within 2 cm from its ostium, which may have been modified by balloon ablation. Results: Discrete MIBG accumulation was generally reproducible in the pre- and postoperative evaluations. The discrete MIBG accumulation value was 2.8 per case, with an average count of 4.15х10 5 PROPCNTS. Of the overall 28 accumulations, 15 had disappeared and three had changed in accumulation level and location after ablation. There was no specific pattern of sympathetic image modification. However, the group in which accumulation disappeared had a significantly smaller cross-sectional area of the pulmonary vein than the group in which it did not (17.2±3.4 mm vs 19.7±1.7 mm, p=0.0056). For reference, the average cryoballoon size was 28 mm. Conclusions: The sympathetic innervation of the left atrium was visualized using MIBG imaging, and the image was modified by cryoballoon ablation. The ability to image sympathetic nerve modification by catheter ablation will be clinically useful.

The Mean

Abstract Background Pulmonary vein isolation (PVI) has become the mainstay of catheter ablation of atrial fibrillation (AF). There are two commonly used methods to isolate the pulmonary veins, either point-by-point delivery of circumferential lesion sets around ipsilateral pulmonary veins using radiofrequency energy, or the application of the cryoballoon to the pulmonary vein antrum with occlusion of the vein ostium. The cryoballoon has proven to be a reliable alternative to radiofrequency ablation in acute and long-term freedom from AF. We describe our results using both modalities. Aim and Objectives to compare the safety and efficacy of cryoballoon (CB) ablation and radiofrequency (RF) ablation in treatment of paroxysmal atrial fibrillation. Patients and Methods Forty-four consecutive patients having paroxysmal AF underwent PVI using the second generation cryoballoon were compared to a retrospective cohort of 69 patients who had radiofrequency induced PVI, either by conventional RF catheter (n = 32), or a contact-force sensing-catheter (n = 37). The study took place at Ain Shams university hospitals and Royal Brompton & Harefield NHS trust. Patient data, procedural data and follow up data- at 3, 6 and 12 months- were collected and analysed. Recurrence was defined as documented AF or atrial arrhythmias with duration exceeding 30 seconds, either by 12 lead ECG or an ambulatory monitoring device. Results A total of 113 patients were studied. The mean age was 53.84 ± 15.01 for the CB group and 55.78 ± 14.84 for the RF group and females representing 40.9% vs 34.8% respectively. The mean procedural times in minutes were significantly less in the CB group (94.37 ± 39.32 vs 184.57 ± 88.19, p < 0.0001), while the median fluoroscopy times were similar [30 (11.04 - 40) vs 37.25 (14.2 - 70), p = 0.172]. Procedural complications were comparable between the two groups (p = 0.06) with 1 patient (2.3%) having long term phrenic nerve paresis. At 1 year follow up, after an initial 90-day blanking period, recurrence rate of CB was similar to RF (27.3% vs 30.4% respectively, p = 0.719), the Kaplan Meier estimates of AF- free survival for a period of 1 year were comparable between both groups (log rank test, p = 0.606). Conclusion Cryoballoon is a feasible method for pulmonary vein isolation with similar success rates to radiofrequency ablation. Cryoballoon ablation is safe with shorter duration of the procedure.
