1 HeartRhythm Case Reports
Is this Vein Isolated or Not? How a New Advanced Algorithm Helps Find Unconventional Far-Field Sources  Francesco Solimene, MD, Francesco Maddaluno, MS, Maurizio Malacrida, MS, Vincenzo Schillaci, MD  HeartRhythm Case Reports  DOI: /j.hrcr Copyright © Terms and Conditions

2 Figure 1 Post-ablation remap of LSPV with the Orion catheter. Two components were detected: the first one was blunt and far-field-looking, while the second was sharp and near-field-looking (“PV-like signal”) HeartRhythm Case Reports DOI: ( /j.hrcr ) Copyright © Terms and Conditions

3 Figure 2 Before ablation, the Orion catheter in the LSPV shows three signals displayed in the left part of each panel. Going from panel A to panel C, the LAW is sequentially placed on each component of the PV signal. Panel A: the LumipointTM algorithm illuminates the LA, which activates simultaneously with the first vein component. Panel B: the LumipointTM algorithm illuminates the LAA, which activates simultaneously with the second vein component. Pacing maneuvers confirmed those signals to be far-field activities from those regions. Panel C: the LumipointTM algorithm illuminates the PV, confirming the last Rapid activity to be the local vein depolarization.

4 Figure 3 On the left (Panel A), pacing with the ablation catheter from the LA pulls the low frequency component detected by the Orion catheter into the pacing stimulus confirming the far field origin from the LA. On the right (Panel B), pacing with the ablation catheter from the LAA, pulls the high frequency component detected by the Orion catheter into the pacing stimulus confirming the far field origin from the LAA.
