Comparative Evaluation of Optrell and Octaray Mapping Catheters for Conduction Block Confirmation and Voltage Assessment During Atrial Ablation

NCT07563257 · Status: RECRUITING · Phase: NA · Type: INTERVENTIONAL · Enrollment: 30

Last updated 2026-06-03

No results posted yet for this study

Summary

This prospective, single-center observational study aims to compare the clinical performance, workflow efficiency, and electrophysiological metrics of two commercially available, high-density multielectrode mapping catheters (Octaray and Optrell) in patients undergoing catheter ablation for complex atrial arrhythmias.

The primary focus is to determine if the real-time vector propagation capabilities of the Optrell catheter combined with V8 software can accurately confirm conduction block across linear ablation lesions without the need for full-chamber activation remapping, which is the current standard of care. A secondary focus will pair-compare the bipolar voltage amplitude distributions recorded by both catheters, given their differing electrode sizes and spacing.
