Does noncontact dipole density mapping improve visualization of propagation patterns during hybrid thoracoscopic ablation in long-term persistent atrial fibrillation?
Noncontact dipole density mapping using the AcQMap system may facilitate hybrid thoracoscopic ablation for long-term persistent atrial fibrillation by providing high-resolution visualization of propagation patterns.
May refine ablation targets in complex arrhythmias; hypothesis-generating and requires prospective validation before wider adoption.
Key Teaching Points•The dipole density (DD) map might provide detail visualization of propagation patterns and potential therapeutic targets for ablation guidance.•AcQMap (Acutus Medical, San Diego, CA) is a noncontact, high-resolution imaging and mapping system that provides heart chamber reconstruction using three-dimensional ultrasound overlaid with high-resolution maps of electrical activation either as DD or as voltage.•Noncontact, DD mapping fairly obviates the technical skill needed for high-density electroanatomic mapping. •The dipole density (DD) map might provide detail visualization of propagation patterns and potential therapeutic targets for ablation guidance.•AcQMap (Acutus Medical, San Diego, CA) is a noncontact, high-resolution imaging and mapping system that provides heart chamber reconstruction using three-dimensional ultrasound overlaid with high-resolution maps of electrical activation either as DD or as voltage.•Noncontact, DD mapping fairly obviates the technical skill needed for high-density electroanatomic mapping.
