Figure Lengend Snippet: Simultaneous unipolar EGMs recorded from the low-density, lower-contact basket mapping catheter and bipolar EGMs recorded from the high-resolution, contact MiFi ablation catheter positioned at the location of an EGF-identified active source located at G6-7. Basket unipolar EGMs at the G6-7 source location are shown in purple (see red box) with the corresponding unipolar EGMs from each closely spaced ablator tip electrode shown in light blue and bipole pairs shown in white. More organized electrical activity is seen on the high-resolution local ablation catheter electrodes (see blue boxes) interspersed with more chaotic fractionated electrical activity (see yellow boxes). MiFi 1, MiFi 2, MiFi 3 = mini-electrode unipoles; MiFi 1-2, MiFi 2-3, MiFi 3-1—mini-electrode bipoles.

Article Snippet: Through the 12-Fr sheaths, long steerable sheaths (AgilisTM, Abbott, Abbott Park, IL) were inserted to facilitate the advancement of a 50 mm basket mapping catheter with 64 electrodes (AblaCathTM; Ablacon, Wheat Ridge, CO and/or FIRMapTM; Abbott, Abbott Park, IL) and an ablation catheter into the right (RA) and subsequently left atrium (LA).
