    Biosense Webster open-irrigated variable-loop circular catheter (vlcc)
    Comparison of a high-density mapping catheter (Octaray) and a variable-loop circular catheter (Varipulse). The larger electrode size and greater inter-electrode spacing of the <t>VLCC</t> influence signal amplitude and morphology. As a result, voltage threshold adjustments are necessary to achieve a mapping performance comparable to that of a high-density mapping catheter.

    Techniques Used: Comparison

    The left figure in each panel shows the high-density bipolar voltage map acquired with a dedicated mapping catheter (Octaray) and displayed with the standard voltage thresholds. The right figures show the maps acquired with the novel variable-loop circular catheter (VLCC, Varipulse) displayed with different bipolar voltage thresholds. Patient #1 underwent an index PVI with four isolated veins after PFA. Patient #2 underwent a redo PVI with a reconnected left lower pulmonary vein at the beginning of the procedure. Patient #3 shows wide antral PVI and scar on the posterior wall during a redo case. Patient #4 presented with an anterior scar. This map was acquired during a roof-dependent flutter, the tachycardia mechanism of which was also correctly identified by the VLCC. PFA, pulsed-field ablation; PVI, pulmonary vein isolation.
