Generation of Patient-Specific 3D Cardiac Chamber Models for Real-Time Guidance in Cardiac Ablation Procedures

Conference paper
Part of the Lecture Notes in Computer Science book series (LNCS, volume 8680)


Cardiac ablation is currently the standard of care for the treatment of certain types of arrythmias [1]. During this procedure, a cardiac electrophysiologist destroys the substrate needed for initiation or sustainment of the arrhythmia using a cardiac mapping and ablation catheter which is placed in the heart transvenously. Electro-anatomical mapping (EAM) tools have enabled real-time guidance and visualization of the catheter and have additional features which facilitate the procedure, such as, real-time visualization of the chamber surface, ability to tag anatomic landmarks and ablation lesions, catheter display, and activation, voltage (or scar) mapping. Herein, we report on the problem of surface reconstruction (SR) from 3D points collected by a novel mapping tool called catheter 3D location system (C3DLS). We highlight the challenges of translating available SR algorithms into a clinical system prototype and discuss our validation strategy. Lastly, we compare our SR results on clinical data to an existing clinical system.
