    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.

    Feasibility of Transatrial Access for Epicardial Ablation Evaluation of 2 Different Techniques in Swine
    (2023) CHOKR, Muhieddine O.; VANDONI, Pedro Mario Pinto; NETO, Jose Nilo de Carvalho; MOURA, Lucas G. de; SOUSA, Italo Bruno dos Santos; AIELLO, Vera D.; BRITO, Fabio Sandoli de; PISANI, Cristiano F.; HARDY, Carina A.; MELO, Sissy L. de
    BACKGROUND The subxiphoid pericardial access is technically difficult and has a considerable rate of complications, thus transatrial access may be an alternative. OBJECTIVES This study sought to assess the feasibility and safety of this strategy regarding periprocedural period and after 1-week follow-up. METHODS The investigators performed epicardial mapping through transatrial puncture in 20 swine. Animals were divided into group A, in which aspiration of the sheath was performed to maintain negative pressure after the withdraw of the catheters, and group B, in which a device (Konar-MF VSD Occluder) was delivered to occlude the right atrial appendage perforation. Bleeding was investigated immediately and 1 week after. RESULTS Access was safe in 19 of 20 animals (95%) with small amount of bleeding (6.4 +/- 6 mL). In group A (n = 10), 1 animal presented hemopericardium right after the puncture. In the other 9, epicardial ablation was performed and 60.0 +/- 28.0 mL of blood was aspirated without events. After 1 week, fibrin-hemorrhagic pericarditis was identified in 3 animals. In group B (n = 10), reaching the epicardial surface was possible in all animals. An adequate position of the prosthesis was obtained in 90% (9 of 10). One death occurred in the immediate postoperative period, secondary to pneumothorax. After 1 week, postmortem analysis showed absence of pericardial bleeding and a normal-appearing pericardium in the 8 animals with adequate prosthesis position. CONCLUSIONS Transatrial access allows epicardial mapping and ablation. Sheath removal after negative pressure contributes to achieving acute bleeding control but does not prevent its occurrence. The use of the device prevents bleeding and hemorrhagic pericarditis.
