Background: Catheter ablation (CA) of atrial fibrillation (AF) is used routinely to establish rhythm control. There is mounting evidence that CA procedures should be performed during continuous oral anticoagulation and direct oral anticoagulants (DOACs) are considered the first anticoagulation strategy.

Methods: IRIS is an Italian multicenter, non-interventional, prospective study which will be enrolled consecutive AF patients eligible for CA and treated with Rivaroxaban; patients in treatment with Rivaroxaban proceeded directly to CA while Rivaroxaban-naive patients were scheduled for CA after 4 weeks of uninterrupted anticoagulation unless the exclusion of atrial thrombi. Rivaroxaban was uninterrupted or shortly uninterrupted (<24 hours) prior CA, in line with routinely practice of each operator. Patients will be followed on continuous anticoagulation for 1 month after the ablation.

Abstract
Background: Catheter ablation (CA) of atrial fibrillation (AF) is used routinely to establish rhythm control. There is mounting evidence that CA procedures should be performed during continuous oral anticoagulation and direct oral anticoagulants (DOACs) are considered the first anticoagulation strategy. Few real-life data are now available and even less in the Italian panorama. Methods: IRIS is an Italian multicenter, non-interventional, prospective study which will be enrolled consecutive AF patients eligible for CA and treated with Rivaroxaban; patients in treatment with Rivaroxaban proceeded directly to CA while Rivaroxaban-naive patients were scheduled for CA after 4 weeks of uninterrupted anticoagulation unless the exclusion of atrial thrombi. Rivaroxaban was uninterrupted or shortly uninterrupted (<24 hours) prior CA, in line with routinely practice of each operator. Patients will be followed on continuous anticoagulation for 1 month after the ablation. The primary efficacy outcome is the cumulative incidence of all-cause death and systemic embolism while the primary safety outcome is the incidence of major bleeding events. The secondary outcomes are represented by non-major bleeding events. All events must be occurred within the first 30 days after the procedure. Results: 250 patients are expected to be enrolled and the study is estimated to be completed by the end of 2022. Up to now 56 patients have been enrolled. Conclusions: This study is the first large Italian prospective study on the management of Rivaroxaban in patients undergoing CA of AF. It aims to depict a comprehensive view of anticoagulation strategy prior CA in several Italian electrophysiology labs.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
