The hybrid thoracoscopic ablation approach, which combines video-assisted epicardial radiofrequency (RF) ablation with endocardial catheter ablation, has proven to be useful in the treatment of persistent atrial fibrillation (AF).1, 2 Standard electroanatomic mapping is based on direct contact to measure the electric field (voltage). Although used in everyday practice in AF ablation procedures, voltage-based mapping demands substantial time and technical ability of the operator. Noncontact, dipole density (DD) mapping fairly obviates the technical skill needed for high-density electroanatomic mapping. 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.3, 4
