Abstract

The aim of this study is to evaluate the feasibility of creating fast three-dimensional maps of coronary arteries and to develop a bipolar coronary guidewire in vitro and determine whether it can be localised accurately within the model.A total of five patients were recruited, and EnSite Precision was utilised to create 3D coronary anatomy. A water bath to accommodate a 3D-printed coronary model was developed to test the performance of the bipolar angioplasty wire.Successful guidewire localisation and 3D reconstruction of coronary anatomy were achieved in all the cases. No complications. The bipolar wire was able to collect point clouds, and localisation of the distal tip was excellent when tested in the water bath.Our study demonstrates the feasibility and safety of utilising EAMS to collect coronary anatomy. Real-time tracking with a bipolar catheter is accurate when tested in vitro.

Keywords: 3D navigation system; Electroanatomical mapping systems; PCI; Percutaneous coronary intervention; Three-dimensional mapping systems.
