Do anatomical and electrophysiological parameters predict successful ablation of premature ventricular contractions originating from the left ventricular summit?
Anatomical and electrophysiological parameters can predict the success of different ablation approaches for left ventricular summit premature ventricular contractions.
Shorter anatomical distances between the epi-EAS and ECS, and between the epi-EAS and LMT ostium, predict a successful ECS ablation. The prematurity of the endo-EAS electrogram and a shorter interval between the epi-EAS and endo-EAS predicted a successful endo-EAS ablation.
