How to perform an epicardial ventricular tachycardia ablation: A contemporary and practical approach

Published:August 25, 2021DOI:https://doi.org/10.1016/j.hrthm.2021.08.024
      Catheter ablation is increasingly used for the treatment of cardiac arrhythmias. In the 1990s, in order to treat ventricular arrhythmias resulting from chagasic cardiomyopathy, Sosa et al

      developed a technique to enter the pericardium percutaneously in the absence of a pericardial effusion. Since then, “dry” epicardial access has become a regular part of complex catheter ablation. In this review, we concentrate on the technical aspects of performing epicardial ablation for ventricular tachycardia (VT), including the management of potential complications.
