Biosense Webster varipulse catheter
Local activation time map (on the left) and voltage map (on the right) of the RA with shadowing of the <t>VARIPULSE</t> catheter location during PFA application with the electrodes in contact with RA wall highlighted and from which PFA was delivered with termination of AT. Phrenic nerve capture sites are indicated by yellow dots . Sites of earliest activation and signals of interest are indicated by black and magenta tags . RF ablation lesions are indicated in red dots . PFA ablation sites are indicated in purple dots . AT = atrial tachycardia; PA = pulse field; PFA = pulse field ablation; RA = right atrium; vRF = radiofrequency.

Figure Lengend Snippet: Thermal surface footprints per electrode with changes in irrigation rates and force with the Varipulse catheter.

Article Snippet: Darkened areas indicative of high temperatures and accompanying dehydration and degradation of the hydrogel and pigment were observed in the Farapulse and Varipulse catheters.

Techniques:

Almost-circumferential thermal footprint when a clinical workflow set of applications is delivered using the Varipulse catheter (left panel). Areas of darkening and scorch in stacked applications with the Varipulse catheter (middle panel). Section through the darkened lesions demonstrating that these changes are observed not only on the surface but also deeper in the hydrogel (right panel). The darkened areas are highlighted with blue arrows.
