Comparison between a Novel Radiofrequency-Balloon and a Standard Cryo-Balloon in Pulmonary Vein Isolation: A Propensity-Score-Matched Analysis Yannick Teumer 1, Clemens Miesbichler 1, ,Carlo Bothner 1 and Karolina Weinmann 1,* 1 Department of Cardiology, Ulm University Heart Center, Albert-Einstein-Allee 23, 89081 Ulm, Germany; Institute for Epidemiology and Medical Biometry, Ulm University, Schwabstraße 13, 89075 Ulm, Germany Abstract: Background/Objectives: Single-shot devices are important tools for efficient pulmonary vein isolation (PVI) in atrial fibrillation (AF). In addition to the standard cryo-balloon (CB) catheter, a novel multi-electrode radiofrequency balloon-catheter (RFB, Heliostar, Biosense Webster, Irvine, CA, USA) with 3D-mapping-integration is available. Currently, there is no evidence allowing for a direct comparison between RFB-PVI and CB-PVI in a matched population. The study aimed to assess the procedural data, safety profiles, and outcomes of RFB-PVI versus CB-PVI. Methods: In this prospective registry study, symptomatic AF patients undergoing first-time PVI from January 2019 to April 2023, using RFB or CB, were included, with patients matched in a 1:2 ratio to reduce potential confounders. Results: The results from 171 consecutive RFB patients and 342 matched CB patients showed comparable recurrence-free survival after 12 months (81.3% RFB vs. 76.8% CB, p = 0.359). The RFB group had a longer procedure duration (88 vs. 73 min, p < 0.001) and longer fluoroscopy time (18.9 vs. 14.5 min, p < 0.001). Conclusions: In conclusion, the novel RFB system enables efficient and safe PVI, which is broadly comparable to the established CB system. However, the 3D-mapping integration in RFB did not reduce fluoroscopy time compared to CB. #VitalStream_Caretaker_type4 #連続心拍出量 #連続ストロークボリューム 研究用 #メディカルテクニカ #Labtech_Holter #生体情報 #Heart_vest_gTec #Pedcath8 #Mennen_Medical #メディカルテクニカ #Labtech_Holter #生体情報 #Heart_vest_gTec #Pedcath8 #Mennen_Medical #Vectorcardiography_Labtech_Holter #VitalStream_Caretaker_Medical #Pedcath8_Mennen_Medical #wvelet_algorithm #Piston_Medical_COanalysi #EWS_Sepsis_Sudden_Cardial_Deah #Vitalstream #Caretaker_type4 #連続心拍出量　#連続ストロークボリューム　研究用　#メディカルテクニカ
