Brief background of the proposal and its relevance to the CDI’s objectives

For patients with cardiac rhythm abnormalities (arrhythmias), ablation procedures are the mainstay of modern therapy. These procedures have been enhanced by the development of electro-anatomic mapping systems, which construct point-by-point maps of the interior heart surface. These systems are limited by the display of key measurements on 2D screens. The skill to mentally relate this data to the overall 3D cardiac anatomy, which is hidden behind the chest wall, remains a daunting challenge for cardiac electrophysiologists. This problem also exists in the cardiac catheterization laboratory, where patients routinely undergo procedures for congenital heart defects with very complicated anatomies. The goal of this project is to develop a novel display system to allow physicians to visualize patient-specific cardiac 3D holograms.

Specific aims

·         Complete a proof-of-concept study for pediatric patients undergoing ablation procedures.

·         Create a workflow to develop patient-specific cardiac models for patients with congenital heart

disease undergoing interventional catheterization.

Potential impact on child health

By facilitating visualization and enhancing interaction with the cardiac model during these procedures, we expect to improve patient outcomes via reduced radiation exposure and shortened procedure time.
