Chagas' disease and recurrent, syncopal ventricular tachycardia (n=1)
Radiofrequency catheter ablation guided by nonsurgical epicardial mapping
Interruption of VT and noninducibility
We report a case of a 63-year-old women with Chagas' disease and recurrent, syncopal VT treated by RF catheter ablation in whom endocardial application of RF energy was guided by nonsurgical epicardial mapping. The procedure was undertaken in the electrophysiology laboratory under deep anesthesia. VT was interrupted after 2.4 seconds of application and rendered noninducible afterwards. Two weeks after the procedure, a distinct morphology VT was induced by programmed ventricular stimulation, and the patient was started on amiodarone, remaining asymptomatic 12 months after the procedure.

Sosa et al. (Fri,) conducted a case report in Chagas' disease and recurrent, syncopal ventricular tachycardia (n=1). Radiofrequency catheter ablation guided by nonsurgical epicardial mapping was evaluated on Interruption of VT and noninducibility. Radiofrequency catheter ablation guided by nonsurgical epicardial mapping interrupted ventricular tachycardia after 2.4 seconds, with the patient remaining asymptomatic at 12 months on amiodarone.
