Catheter Ablation to Treat Sustained Ventricular Tachycardia in Patients With Chagas Cardiomyopathy and Implantable Cardioverter-Defibrillator

In treating hundreds of patients with these characteristics, we were able to define the substrate of most of these VTs: most re-entrant circuits in Chagas VTs originate in the inferior or lateral basal wall of the left ventricle. [...]after developing the technique of subxiphoid percutaneous access...

Description
Summary:In treating hundreds of patients with these characteristics, we were able to define the substrate of most of these VTs: most re-entrant circuits in Chagas VTs originate in the inferior or lateral basal wall of the left ventricle. [...]after developing the technique of subxiphoid percutaneous access to the pericardial space in our laboratory, we were able to identify that subepicardial myocardial fibers were the cause for re-entrant circuits of sustained VT in many patients with Chagas disease (8,9).
