Overview

Observational analysis identifies right ventricular false tendons as arrhythmogenic substrates for PVCs, suggesting improved ablation protocols.

Key Points

  • All identified RVFTs in the free wall contribute to arrhythmogenic PVCs originating from the right ventricle.
  • Utilization of ICE for 3D anatomical reconstruction significantly enhances target location and successful ablation outcomes.
  • Morphological and histological evaluations of RVFTs reveal cardiac muscle composition that may trigger PVC activity.
  • RVFTs serve as crucial electro-anatomical substrates for understanding PVC mechanisms and guiding effective treatments.
