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…

Hx of PVI, PWI, LAA isolation, and LA CFE. Mitral circuit using a low voltage channel on the roof and the ridge, PAC from the channel reset tach CL, confirming the isthmus. Our first lesion on the channel terminated flutter. #PMA Jeff Hsing Brock Gambill

Farfield earliest activation corroborated with downstroke notch in V1, localization RCC/LCC commissure. innovationsincrm.com/cardiac-rhythm… Initial RF lesion resulted in PVC suppression. Aortic cusp commissure imaged Abbott Cardiovascular #ViewMate. #PMA Ashit Patel Jordan Hemmen

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/

An untouched atrium, presenting with concordantly positive p-waves. A Reset ExtraStimulus Map helped limit ablation beyond PVI, despite multiple areas of deceleration and potential participating circuits. #PMA #Entrainment Ashit Patel Jordan Hemmen Abbott Cardiovascular

First of 3 posts on this case. Started case with Clockwise Mitral flutter despite posterior wall scar #PMA

2nd post: Terminated Mitral to second flutter. Can you see what it is on the left side of the screen? #PMA

Increased ectopy during ablation at this AT’s site of earliest activation, demonstrating irritation of the tachycardia’s focus Jaylynn Markey Emily Shaw #PMA

S3 protocol, once again proved valuable in identifying ablation targets within this complex ischemic substrate. Impressive decoupling of EGM's, otherwise missed with fixed S1 mapping. #AblateVT European Society of Cardiology Journals Abbott Cardiovascular academic.oup.com/europace/artic…

Hx PVI + PW, presenting with typical AFL. CTI & re-isolation of LPV performed. During left atrial post mapping, induced 230 msec tachycardia. Inadvertently terminating during left atrial mapping, though incomplete, passively activated. Unable to reinduce. Right Atrial, S3

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 pmc.ncbi.nlm.nih.gov/articles/PMC81…

Premature His Bundle Complexes distinguished AVRT and AVNRT with 100% Specificity and Sensitivity irrespective of location. A simple & intuitive maneuver. PHC delivered 42 msec ahead of HIS, perturbed A1-A2 by 15 msec = AVNRT. Benzy Padanilam Ashit Patel Emily Shaw

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 Brittany Metzler Madison West-Cary D Randy Jones

Monday started with First-in-Human Use of “ViewFlex X SE” ICE Catheter with Abbott Cardiovascular I've always loved using the ViewFlex ICE for its exceptional image quality, but now with seamless ICE integration into Ensite X, this is a total game-changer that enhances precision like

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…

A mappable VT meandering through WaDLs / Lines Of Block. Intuitive S3 Protocol discontinuities, 98% Correlation Score, and VT activation maps, supported a thoughtful ablation strategy. #EnSite Abbott Cardiovascular

Despite multiple PFA applications, unable to achieve anterior block for mitral flutter. Epicardial voltage with peak frequency emphasis highlighted RF target. Lateral splits seen after first TactiFlex application. #HDGrid Abbott Cardiovascular D Randy Jones
