Acute and one year outcome of premature ventricular contraction ablation guided by contact force and automated pacemapping software.

ABSTRACT:

Background

Radiofrequency (RF) ablation is a well-established approach to treat premature ventricular contractions (PVC) and is associated with good outcomes.

Aim

The present study sought to analyze the acute efficacy and 1-year outcomes of PVC ablation using RF technology with an approach based on automated pace-mapping and contact force (CF) information.

Methods

Sixty-one consecutive patients (52.4% males, age 45.9 ± 12.5) underwent catheter ablation for symptomatic monomorphic PVC. All procedures were guided by a 3-dimensional mapping system; site of ablation was selected based on PASO^™ aided pace-mapping; RF was started on the selected location when stable catheter position with >10 g of CF were obtained.The procedure was defined as acutely effective if
