Improving procedural and one-year outcome after contact force-guided pulmonary vein isolation: the role of interlesion distance, ablation index, and contact force variability in the ‘CLOSE’-protocol

Structured PICO

Does 'CLOSE'-guided PVI improve procedural and 1-year outcomes compared to standard CF-guided PVI in patients undergoing pulmonary vein isolation?

Population

Patients undergoing contact force-guided pulmonary vein isolation (PVI)

Intervention

'CLOSE'-guided PVI (strict application of criteria for contiguity and ablation index)

Comparator

Standard contact force (CF)-guided PVI

Outcome

Procedural outcome, 1-year outcome, and procedure time

The 'CLOSE' protocol for PVI improves procedural efficiency and 1-year outcomes by standardizing interlesion distance and ablation index.

Abstract

'CLOSE'-guided PVI improves procedural and 1 year outcome in CF-guided PVI while shortening procedure time. Improvement cannot be explained by differences in CF variability and is most likely due to the strict application of criteria for contiguity and ablation index. A randomized controlled trial is needed to exclude the possible contribution of a learning curve.
