Redo with Hx PVI, CTI & Roof dependent AFL. Mapping revealed narrow passage through roof encompassing 80% of TCL. Linear #TactiCathSE was unable to appreciate isthmus EGM’s by #HDGrid. Unipolar Voltage complimented LAT and #Entrainment maps. Successful endpoint D Randy Jones

Redo PVI pt. presented to @dsabayon at UTMB Health with roof dependent LAFL. INTELLAMAP ORION™ collected 7500 EGMs in 5 min. The arrhythmia was terminated with DIRECTSENSE™ with a line of block across the high voltage area between the LIPV & RIPV.

Based on the twitter posted by Syamkumar How can we make a accurate diagnosis from a challenge telemetry tracing of Wide complex tachycardia? Labadet et. al. from Argentina found this interesting finding. It worths reading it. doi: 10.1093/europace/eux103.

Interesting PVC at MUSC Health with Jeffrey Winterfield. PVC was quickly mapped to lateral wall near ALPM insertion. A False Tendon was seen on ICE connecting from PM to basal Septum. LAT there was earlier than rest of septum. Are we seeing the FT activation?#Epeeps Abbott Cardiovascular 1of3

Challenging case of PMpap VT runs/PVC’s with marked TCM( EF:15%) in a young male; large LV ; TS approach;so catheter stability was a problem!( was not better with TA as well) finally we got it here👇!😰 40-45wts/ HNS/120s with consolidation burns! #Epeeps

The anterior right pulmonary vein antrum, an under appreciated topography? Atrial diverticulum seen here, perhaps culprit of temperature & impedance limiting during Radiofrequency #Ablation. Imaged during unrelated, Focal Atrial #Tachycardia #Ultrasound #EPeeps credit Ashit Patel

.Philipp Sommer We need a new classification for #AFib! There is a disconnect between current classification / phenotype and underlying substrate. ➡️PVI-dependent vs non-PVI dependent may be more accurate and more predictive of success Need mechanistic understanding! #WAFib2023

Neat addition to localization algorithms for R/L manifest accessory pathways. Using P-Delta Interval, R/S ratio, and QRS onset polarity in lead V1. Proved consistent with this #WPW.

In the setting of redo accessory pathways, the tricuspid annular variety hosts highly complex atrial & ventricular electrograms. This stability-limited location makes for the unique signal characteristics seen here in ORT. Jaylynn Markey Austin Cummings Abbott Cardiovascular

How to avoid AF recurrence in atrial fibrillation? Lesion formation geometry is crucial, resistive vs. conductive heating lesion durability. More to come in LAHRS 2023. Thanks to Jose Osorio for being a great educator and Elad Anter for publishing disrupting science.

#EPeeps Is it possible to capture / conceal into slow pathway? Are there other explanations for what’s happening here? No lines of block in atrium. Pacing from abl at 4 o’clock at 10mA on TA. #PMA Syamkumar Brock Gambill
