“…While this is an improvement over conventional RF and cryoablation other technologies have emerged, such as the QDOT (Biosense Webster) ablation catheter and pulsed field ablation. Initial studies have quoted ablation times of 8.1 minutes utilizing high power with the QDOT catheter and 3 minutes with pulsed field ablation 9,10 . It remains to be seen whether these technologies are as effective as the RF balloon or as easy to use.…”

Background: The RADIANCE first-in-man study evaluated acute (3-month) safety and design concept in terms of utility of a new multi-electrode radiofrequency (RF) balloon catheter (HELIOSTAR, Biosense Webster) to achieve pulmonary vein isolation (PVI).After study conclusion, a subset of patients was followed up to 12 months.Methods: Patients with drug refractory paroxysmal atrial fibrillation were enrolled.Neurological assessment, cardiac and cerebral magnetic resonance imagings were performed pre and post procedure. Ablation was delivered at 15 Watts to each PV for 60 seconds (electrodes adjacent to the posterior wall limited to 20 seconds). Adenosine or isoproterenol was administered to confirm PVI. Esophageal endoscopy was performed 48 hours post procedure. Patients were clinically followed up for 12 months.Results: Thirty-nine patients underwent catheter ablation from four centers. Mean age was 60.7 ± 10.0 years with 23 (57.5%) being male. Confirmation of PVI was performed in all PVs treated (152/152). Confirmation of isolation after one delivery was performed solely on 137 of 152 PVs of which 79.6% (109/137) achieved isolation with a single delivery of RF energy. Acute PV reconnection was seen in 4.6% (7/150) of PVs. Freedom from documented atrial arrhythmia at 12 months in those followed up was 86.4% (32/37). A total of 75.7% (28/37) of patients were free from atrial arrhythmia and off antiarrhythmic medications. Conclusion:The HELIOSTAR RF balloon catheter allows for rapid and safe PVI with majority of PVs only requiring one application.

“…The feasibility and safety of HPSD strategy during AF ablation has already been confirmed in a clinical setting [80]. Additional advantages of this procedure are the possible decreases in procedure and fluoroscopy times, particularly when novel catheter technologies, such as the QDOT-FAST catheter, are used [81].…”

Purpose of Review: Atrial fibrillation (AF), the most common sustained arrhythmia, is associated with high rates of morbidity and mortality. Maintenance of stable sinus rhythm (SR) is the intended treatment target in symptomatic patients, and catheter ablation aimed at isolating the pulmonary veins provides the most effective treatment option, supported by encouraging clinical outcome data. A variety of energy sources and devices have been developed and evaluated. In this review, we summarize the current state of the art of catheter ablation of AF and describe future perspectives. Recent Findings: Catheter ablation is a wellestablished treatment option for patients with Enhanced Digital Features To view enhanced digital features for this article go to https://doi.org/10.6084/ m9.figshare.11357912.
