Transmural Electrophysiological Imaging to Guide Catheter Ablation of Arrhythmias

Linwei Wang, Principal Investigator

Cardiac arrhythmia accounts for increasing risk for all strokes (15%), heart failure, and mortality. The currently used minimally invasive procedure, i.e. catheter ablation, relies on point-by-point contact mapping on the heart surface to construct a 3D map of activation sequence.

Such invasive methods have limitations in application to humans, preventing continuous mapping with insufficient resolution in a closed chest. Transmural electrophysiological imaging (TEPI) is a new concept we introduced to overcome the limitations that have been associated with the current paradigm of invasive mapping.
