I.- Initial experience on cardiac magnetic resonance-aided VT ablation in South America(2023) PISANI, Cristiano F.; ALEXANDRE, Felipe Kalil; KULCHETSCKI, Rodrigo; MAYRINK, Marina; WU, Tan Chen; CHOKR, Muhieddine; HARDY, Carina; MELO, Sissy Lara; ROCHITTE, Carlos; NOMURA, Cesar; SCANAVACCA, MauricioBackground: 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.

- Applicability of the PAINESD risk score for 30-day mortality prediction post ventricular tachycardia catheter ablation in Chagas disease(2021) KULCHETSCKI, R. M.; PISANI, C. F.; ALEXANDRE, F. K. B.; MAYRINK, M. P.; FERRAZ, A. P.; GOUVEA, F. C.; GONCALVES, A. L. M.; HARDY, C. A.; MELO, S. L.; CHOKR, M. O.; SCANAVACCA, M. I.Purpose The PAINESD risk score was developed in 2015 as a tool to stratify the risk of acute hemodynamic decompensation during ventricular tachycardia (VT) ablation in structural heart disease patients and further then used for post procedure 30-day mortality prediction. The original cohort however did not include Chagas disease (ChD) patients. We aim to evaluate the relevance of the score in a ChD population. Methods The PAINESD risk score gives weighted values for specific characteristics (chronic obstructive pulmonary disease, age > 60 years, ischemic cardiomyopathy, New York Heart Association [NYHA] functional class 3 or 4, ejection fraction less than 25%, VT storm, and diabetes). The score was applied in a retrospective cohort of ChD VT ablations in a single tertiary center in Brazil. Data were collected by VT study reports and patient record analysis at baseline and on follow-up. Results Between January 2013 and December 2018, 157 VT catheter ablation procedures in 121 ChD patients were analyzed. Overall, 30-day mortality was 9.0%. Multivariate analysis correlated NYHA functional class (HR 1.78, 95% CI 1.03-3.08, P 0.038) and the need for urgent surgery (HR 31.5, 95% CI 5.38-184.98, P < 0.001), as well as a tendency for VT storm at presentation (HR 2.72, 95% CI 0.87-8.50, P 0.084) as risk factors for the primary endpoint. The median PAINESD risk score in this population was 3 (3-8). The area under the receiver operating characteristic (ROC) curve was 0.64 (95% CI 0.479-0.814). Conclusions The PAINESD risk score did not perform well in predicting 30-day mortality in ChD patients. Pre-procedure NYHA functional class and the need for urgent surgery due to refractory pericardial bleeding were independently associated with increased 30-day mortality. Prospective studies are needed to take final conclusions in Chagas disease when using PAINESD score.
