What is Cardiac Mapping?


Mapping the electrical activity of the heart is a critical component for the diagnosis and treatment of heart disease. Many advanced therapies (such as ablation for the treatment of arrhythmias) require detailed electroanatomic mapping. Currently, mapping is performed in an electrophysiology (EP) lab, during which mapping catheters are inserted into the heart and carefully moved to various locations around the heart to map and identify the origins of the arrhythmia. Once the origin of the arrhythmia is identified, the specific tissue is destroyed by ablation. Current catheter mapping technologies have several limitations including:

  • Risks and limitations associated with being an invasive and time consuming procedure.
  • Current point-to-point mapping technology does not provide simultaneous, beat-by-beat mapping. Electrical activity has to be skillfully aggregated and annotated to make sense of the information provided by these point-to-point mapping systems.
  • Does not provide the whole picture (bi-atrial or bi-ventricular) of electrical activity. Only provides mapping information one chamber at a time.
  • Does not fit into the current work flow of device based therapy (e.g. Cardiac resynchronization therapy devices for heart failure).

Catheter ablation hasĀ evolved to become a mainstream treatment for arrhythmias, while mapping to identify ablation treatment targets and confirm success of therapy has emerged as its significant and critical counterpart.

For device-based therapy like Cardiac Resynchronization Therapy (CRT) for heart failure, point-to-point, non-simultaneous catheter mapping provides very limited benefit while adding cost and complexity to the procedure. Therefore, there is no practical mapping solution available for use today.

CardioInsight's ECVUE system has the potential to substantially improve EP clinical practice by addressing significant unmet clinical needs associated with current mapping technologies.
