#ViewFlex with #ViewMate Multi confirming #TactiFlex location and contact during CTI ablation #PMA

Prior PVI and PWI. Narrow channel of slow conduction on the roof identified by #HDGrid. Entrainment yields a return interval of 0 ms; the roof is in this atypical flutter’s circuit. #Entrainment #PMA @bmetzlerEP @madiwcEPdrop @EPS_PDX

EnSite VT map hypothesis confirmed. Entrainment with concealed fusion, PPI = TCL. Downstream Pacing with long Upstream Capture observed, S-Vu >75% TCL @CRB_EP @DrGregMichaud @AbbottCardio

Alternative form of entrainment with a sensed extrastimulus beat from a site of late activation. The paced wavefront travels orthodromically, captures atrial EGMs upstream, and resets the tach. The RA lateral wall is within the tach circuit. #PMA #REM https://t.co/D1HmwLgTXT

Increased ectopy during ablation at this AT’s site of earliest activation, demonstrating irritation of the tachycardia’s focus @JaylynnMariePDX @EP_EmilyS #PMA

Clinical PVC mapped to moderator band via continuous score mapping with a correlation of 96%. The PDX technique was employed to project points to endocavitary structures, enabling precise identification and visualization of the ablation target. #PMA https://t.co/mHy4J0K4Z7

Diagnostic maneuvers being the easiest part of this procedure. Intracardiac Echo imaging for the more challenging part, #Ablation. The classically unstable, right superior lateral Tricuspid Annular accessory pathways. Here, direct approach versus loop was performed, due to

A Nodal response to Parahisian Pacing was surprisingly discordant to a timely PHC delivered <20 msec to measured HIS bundle potential during tachycardia, perturbing subsequent A. Earliest A mapped to Superior Lateral Tricuspid Annulus, participation confirmed with reset. Always
