Entire cycle length of 2:1 tach seen in Right Superior Pulmonary Vein. PVI restored patient to NSR #PMA Cat Capper EP

S/P PVI and PWI ablation, a 445ms flutter found its way through a recovered voltage channel. First burn with #TactiCathSE lead to successful termination #PMA Cat Capper EP

Posterior wall once again isolated with complete roof and floor line

Open Window Mapping (OWN) used to highlight the ventricular insertion of this posterior #WPW . Lost pre-excitation with 2 seconds of RF #PMA

Patient presented with stable 260 msec incessant tachycardia. Unusual P-Wave to be localized to LA side of Bachmann's Bundle insertion for this seemingly centrifugal / microreentrant AT. Prior CTI only. Jeff Hsing Jamison Nutting - EP Abbott Cardiovascular #SVT #PMA #TactiFlex

Persistent AF. A realtime snapshot of #PVI + PW. HPSD, FPI with #TactiFlex Credit Edward Cheng, MD, PhD Abbott Cardiovascular

ECG morphology similar to sinus. Crista AT mapped and ablated. Irritability seen upon initial RF application. #PMA Sandeep Saha, MD MS FACC FHRS

Cryo & RF for PVI + PW + CTI in 2021. AF cardioverted, SR mapped, Voltage with Fractionation map highlighting RPV antrum ablated. Veins and Posterior Wall remain isolated, CTI assessed conduction leak at annulus. D Randy Jones #PMA #TactiFlex

Substrate/decel zone based VT ablation in LVOT/ anterior septum in mixed CM correlating with exit of clinical VT Pt with preéxisting CHB so His/LB not an issue. Transeptal access due to comorbid PAD. Non indicible Excellent mapping George Crowell #EPeeps

PAC perturbs HIS but does not affect A-A proving AT #PMA D Randy Jones Lydia Trautmann

Happy Fib Friday! Live images during recent AF procedures. Accurate anatomy makes for a seamless ablation with #TactiFlex #PMA

Right lateral accessory pathway, although difficult to get contact and stability, successful ablation within 3 seconds Lydia Trautmann #PMA

Prior PVI, PWI, CFE, and anterior septal line. Biatrial flutter circuit mapped with #HDGrid, using epicardial connection to jump across to RA. Entrainment confirmed circuit, ablation of mid anterior line broke rhythm and never reinduced. #PMA Jeff Hsing Brock Gambill

CS pacing reveals an increase in transisthmus conduction time across the CTI during ablation with #TactiCath. 3D block confirmed after completing the line #PMA

Prior cryo and CTI line for this patient, returned in atypical flutter. Fractionation and slowing on both the roof and mitral annulus, collision on CTI. Where to burn first? #PMA

Projection Overlap Map (POM) to show locations with multiple therapy applications in PFA cases. Here are the map settings we landed on using the “Point Count” map type. Looking forward to seeing what clinical utility this has, and also how the Abbott Cardiovascular teams continue to

Abrupt V3 transition with V2 pattern break, and this time got it from R-L interleaflet triangle (ILT) within seconds. 27 ms pre-QRS. V2 pattern break so likely too close to pLAD from GCV/AIV, so didn’t waste time there. Great mapping George Crowell #EPeeps

Another iatrogenic flutter- this case in the right atrium on a patient with prior ablation of typical flutter + RA focal AT. Not typical CTI flutter this time, but still CTI-dependent! 🎡 Where would you ablate? ⚡ #EPeeps

Live screen grab from recent first pass PVI with #TactiCath Total RF time of 730sec #PMA Ashit Patel
