LONG-TERM DATA IN AF PROCEDURES SHOWS IMPROVED OUTCOMES WHEN USING ADVISOR HD GRID MAPPING CATHETER, SE1

A new manuscript published by Dr. John Day, et. al comparing long-term outcomes of AF procedures completed with a circular mapping catheter (CMC) to those completed with the Advisor HD Grid Mapping Catheter, SE found that the use of the Advisor HD Grid Mapping Catheter, SE resulted in a:

WHEN YOU CHECK FOR GAPS IN PULMONARY VEIN ISOLATION, ARE YOU SEEING THEM ALL?

Acute data collection that includes both direct and indirect comparisons of the Advisor™ HD Grid Mapping Catheter, Sensor Enabled™ in standard pulmonary vein isolation (PVI) confirmation workflows suggests that the device can identify gaps that may be missed by other technologies.
 

Now Includes Expanded Data Sets

Circular Mapping Cathethers2

The incidence and location of gaps following PVI were tracked utilizing either a circular mapping catheter (CMC) or the Advisor™ HD Grid Mapping Catheter, SE.
 

Isolation was tracked across 559 cases

HD Grid Mapping Cathethers 52.5%

Cryoablation3

In a direct comparison, 150 patients received cryoballoon ablation with isolation confirmed by the Achieve Mapping Catheter. Isolation was then checked again with the Advisor HD Grid Mapping Catheter, SE, revealing:

27.3% of patients with greater than or equal to 1 gap missed by the Achieve Mapping Catheter.
12 total gaps missed by the Achieve Mapping Catheter were identified by the Advisor HD Grid Mapping Catheter, SE.

Pacing Ablation Line4

In a direct comparison, 111 patients received ablation with isolation confirmed by pacing the ablation line. Isolation was then checked again with the Advisor HD Grid Mapping Catheter, SE, revealing:

15 patients with greater than or equal to 1 gap missed by pacing.
30 total gaps missed by pacing were identified by the Advisor HD Grid Mapping Catheter, SE.
