Resumo
Background: Cardiac magnetic resonance (CMR) allowed to precisely identify the substrate in scar-related ventricular tachycardia (VT). New software has been developed to define the 3D scar and corridors to help VT ablation by integrating the scar and electroanatomical mapping (EAM). The objective of this study is to evaluate the results of VT ablation aided by the integration of EAM and CMR software processed scar.Methods: We selected patients that underwent VT ablation with the integration of EAM and CMR processed using ADAS software and imported to the CARTO system using VTK file format.Results: From 2019 to 2021, eight patients (mean age 63 +/- 4.4, 62.5% male; EF 47 +/- 12%) underwent CMR-aided VT ablation. Mean procedural time was 281 +/- 77 min. There was of 9 +/- 4.4 epicardial and 7.9 +/- 4.3 endocardial bulls eye segments with at least 2 g of border zone or core scar. In a median follow-up time of 532 days (Q1: 284, Q3: 688), three patients (37.5%) presented VT recurrence, all three underwent a second procedure, with no VT recurrence on the follow-up. No patient died in the follow-up.Conclusion: CMR aided is ablation is feasible and effective in patients with scar related VT.
