Introduction: Electroanatomical 3D-visualization is the gold-standard for guiding the treatment of complex atrial and ventricular arrhythmias. However, detailed depiction of anatomical details that may be crucial to procedural success remains challenging.
Methods: KODEX-EPD is a novel cardiac electroanatomical imaging system. It utilizes wide band dielectric sensing and a unique bending of electric fields technology to generate high-resolution images of the cardiac anatomy. The acquisition process involves contact and non-contact mapping maneuvers using any diagnostic or ablation catheter. Here, we report our initial experience in left atrial anatomical mapping from a patient undergoing pulmonary vein isolation. The procedure was performed according to our institutional standard approach, performing electroanatomical mapping using Carto 3 and selective pulmonary vein angiography. No further cardiac imaging was performed. For this initial study, data collection for KODEX-EPD was executed passively and the acquired image was analyzed offline.
Results: Figure 1 illustrates a panoramic view of the left atrium. For this innovative view, the atrium is opened virtually along the anterior wall, allowing unrestricted view of anatomical features previously obscure to the clinical electrophysiologist. The pulmonary vein ostia (RPV and LPV), the mitral valve, the left atrial appendage (LAA) and the ridge towards the left sided veins are depicted in great detail. Of note, an accessory pulmonary roof vein (*) was also visualized.
Conclusion: Anatomical mapping of the left atrium using KODEX-EPD bears the potential to create CT-like images without the need for additional periprocedural imaging.
