  • This core curriculum session from Heart Rhythm 2018 will provide an overview and update on the pathophysiology underlying ventricular arrhythmias, the indications and outcomes of VT ablation procedures, and a variety of strategies to improve mapping of ventricular arrhythmias within the EP laboratory.

The session is 90 minutes in length and is comprised of four presentations:

  • Idiopathic vs Scar Related Ventricular Arrhythmias: Review of Pathophysiology and Arrhythmia Mechanisms 
  • Indications, Procedure Complications, and Outcomes in PVC and VT Ablation 
  • Tools and Techniques to Optimize VT Ablation: High Resolution Mapping, Hemodynamic Support, and Imaging 
  • PVC-induced Cardiomyopathy: How to Prevent, Predict and Treat

Learning Objectives

  • To review updates on the latest developments in VT pathophysiology and substrate assessment
  • To outline current indications for VT ablation procedures and associated outcomes
  • To review the role of mapping, hemodynamic support, and imaging modalities during VT ablation
