VX1 CLINICAL EVIDENCE Ev-AIFib2 Ev-AIFib2 is a prospective, multicentric, non-randomized study conducted to determine the feasibility and relevance of constructing VX1 dispersion maps for the ablation of persistent AF and that the use of VX1 allows for a robust center-to-center standardization of ablation outcomes. 12-Month Follow-up persistent & long-standing persistent AF patients sites (1 primary center and 7 satellite centers) operators using the 3 major mapping systems. Acute termination After single procedure Freedom from AF/AT* After one or multiple procedures (average of 1.3...
