Biatrial Global High-density Electroanatomical Mapping of Atrial Fibrillation

NCT03812601 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 22

No results posted yet for this study

Summary

This study uses two AcQMap imaging and electroanatomical mapping systems (Acutus Medical) to simultaneously visualise and map patterns of wavefront propagation in both the left and right atria during atrial fibrillation in order to identify mechanisms of rhythm propagation and maintenance and the importance of the interaction of the left and right atria. Mapping will also be performed during pacing from different sites and cycle lengths to identify regions of abnormal conduction that may be related to the maintenance of atrial fibrillation.

Interventions

PROCEDURE

Simultaneous bi-atrial electroanatomic mapping and ablation

Simultaneous bi-atrial electroanatomic mapping during atrial fibrillation and during pacing from 3 different vectors at varying cycle lengths followed by pulmonary vein isolation and AcQMap guided ablation of non-pulmonary vein mechanisms.
