PVC mapped to the apical base of AL Pap, predicted by ECG. #PDXTechnique used to highlight earliest, ablated using #TactiCath ahajournals.org/doi/full/10.11… #PMA

At this clinical PAC’s earliest, the QS unipole indicates the origin of the wavefront as conduction moves away from the recorded EGM. Compared to NSR, a RS unipole is seen, demonstrating the change in conduction towards and then away from the area #TactiCath #PMA Lydia Trautmann

PVC with abrupt V3 transition suggested L-R interleaflet triangle exit. Broad left sided early activation and poor pace mapping. Got it from below pulmonic valve w/ 98% match. Anatomy relationship always an a-ha moment. Excellent mapping Brock Gambill George Crowell #EPeeps

intramural LV summit PVC with V2 pattern break, broad exit. Hit it from both LV endocardium and LCC. Half normal NS RF for up to 2 min, ~700 mA current, and anterior ground location critical for success. Excellent mapping Brock Gambill #EPeeps

Earliest signal mapped on LCC side of commissure. Interestingly, best pace match from the RCC side #PMA Saket Sanghai MD FACC FHRS Jaylynn Markey

AVRT via branched concealed let sided AP. Mapped and a ablated during incessant tach. First lesion at early spot with AP potential changed TCL and earliest A. Second location more lateral also with AP potential terminated in 6 sec. Great mapping at Arek Karagoezian Lydia Trautmann #EPeeps

Always wary when EKG shows right anterolateral for WPWs, but even with challenging stability, we were able to successfully ablate this AP with #TactiFlex. Antegrade map on left and V pace map on right in both images. #PMA

Patient Hx 3 yrs post Cryo PVI & CTI. 3 months post PFA of posterior wall. Presented in 340 ms tachycardia. #HDGrid showed scarring with slow conduction through left atrial roof and floor. Termination at isthmus, confirmed with entrainment, with #TactiFlex. Lydia Trautmann #PMA

Atrial overdrive pacing suppresses the tachycardia and upon resumption, an AH-HA response is observed. Junctional tachycardia confirmed following this SP modification. #PMA Brock Gambill sciencedirect.com/science/articl…

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 pubmed.ncbi.nlm.nih.gov/33515142/

A patient frequently burdened with these PVC's originating at an anterior lateral attachment network of trabeculae carneae. Elongated strands of muscles lining the LV that attach to the solid portion of the LV wall. Permanently suppressed by #TactiFlex at site of 99%

The notorious papillary muscle PVC. Originating from lateral aspect of the pap, these bigeminal PVCs were eliminated during the first RF session with the help of the tried and true PDX method. Link to publication: pmc.ncbi.nlm.nih.gov/articles/PMC81…
