Redukcja ekspozycji na promieniowanie podczas ablacji migotania przedsionków z wykorzystaniem systemu elektroanatomicznego 3D zintegrowanego z fluoroskopią w codziennej praktyce klinicznej.

Introduction:Fluoroscopy integration with three dimensional (3D) electroanatomical mapping system may allow dose reduction while invasive electrophysiological procedures. In this retrospective study we present real-population experience with integrated model. Material and methods:96 patients with paroxysmal AF after radiofrequency (RF) pulmonary vein isolation (PVI) have been analyzed. In 48 patients, 3D mapping system integrated with fluoroscopy (Carto 3 UniVu) has been used. Clinical and peri-procedural data, inclusive, fluoroscopy time and dose, in-hospital complications and efficacy rate at 6 months have been compared. Results: Patients treated with classic 3D mapping system were significantly older (p=0.036). Both fluoroscopy mean time (11.6±4.3 vs. 6.7±2.9 minutes, pu003c0.05) and a median of the fluoroscopy dose (460.0 [IQR: 288.0; 785.5] vs. 271.0 [IQR: 145.0; 535.0] mGy, pu003c0.05) have been significantly reduced by using Carto3 UniVu. Total procedure time was comparable between groups. Periprocedural complications and recurrence of clinical arrhythmia rate in 6-month follow-up were comparable. Conclusions: Utilization of novel 3D mapping systems with classic fluoroscopy integration support the radiation time and the dose reduction during AF ablation procedure, without any adverse impact on the total procedure time neither complication or success rate. This real-life population results corresponds with previously presented prospective studies.
