Jass Brooks, vice president of global strategic marketing, Biosense Webster, explains four over-arching electrophysiology (EP) trends at the 2021 Heart Rhythm Society (HRS) meeting. The vendor is working on developing, or has introduced, new technologies in each of these four areas. She said the key technology trends include:
• Pulsed field ablation (also called electroporation) as a new way to ablate cardiac tissue without damaging underlying structures like the esophagus.
• The introduction of 3D/4D intra-cardiac echo (ICE) imaging to better guide procedures.
• High-density electromapping systems that create more accurate maps of the electrical activity in the heart and can do so faster than previous generation mapping systems.
• The introduction of artificial intelligence (AI) into EP systems to speed workflow.
Key among this company's new product introductions at HRS 2021 was the Octaray high-density electro-mapping catheter, which enables faster mapping with a larger number of points. This enables more detailed maps of the heart's electrical activity and may imporve ablation procedure guidance and outcomes. Recent changes to the Carto electro-mapping system now enables integration of this new technology.
Biosense Webster also introduced the Nuvision 4-D intra-cardiac echo (ICE) ultrasound catheter with imaging support from GE Healthcare Vivid Ultra Edition ultrasound systems. This moved ICE beyond 2-D imaging to real-time 3-D and 4-D imaging inside the heart to enable better procedural navigation and visualization of the catheters within in the heart.
