Feel like our published CR about the coronary spasm during pulsed field ablation at the mitral isthmus line got some attentions during the last weeks' (inter)national EP meetings... what do you think about it? doi: 10.1016/j.jacep.2021.08.016. #EPeeps #JACCJournals #JACCEP

Snapshot of left atrial flutter with prior PVI. CS paced map, revealed #ILAM & #DZ Christopher Woods predicted circuit isthmus. Closed Window Technique right, displaying voltage with usual high correlation. Entrainment confirmed Abbott Cardiovascular #PDXMapping Brock Gambill Paige Mazur

Complete circuit #StaMP #EGM CS pacing map right, NNE entrainment map left. Downstream pacing site (late to p-wave) displaying long stim to upstream capture, (iegm to surface p fusion) reentry. Christopher Woods Ashit Patel Paige Mazur x.com/ashit_eps/stat…

Macroreentrant, despite 90% CL localized to LSPV/LAA ridge, determined a dead-end tract with ppi-tcl 130, color entrainment map imaged. Closed Window Technique displayed isthmus anterior and further septal to LAA. Voltage shows PV’s / PW isolated. D Randy Jones

An endless 315 msec loop around surgical ASD repair. Locally synchronized 600 msec pacing for phrenic nerve localization produced a neat response, a 2 to 1 Downstream Pacing with long Atrial Upstream Capture, image 2. Gregory Michaud NNE of 1’s? #EPeeps #Entrainment

Nice set up Ashit Patel. Thanks for sharing this moment and for your commitment to excellent #PatientOutcomes in the EP lab. Important Safety Info: cardiovascular.abbott/us/en/hcp/prod…

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

My new favourite entrance to a cardiac department!! (Created by Angela Palmer) #echofirst #cardiotwitter #whyCMR

Timing, location, or both? Gifted with this non-propagated stimulus delivered within coronary sinus, terminating typical AVNRT. Concealed into slow pathway? As described by Dr.’s Thomas Dewland, Mel Scheinman, MD & Greg Marcus? HeartRhythm heartrhythmjournal.com/article/S1547-… #EPeeps

Enjoying this collaboration with my beloved colleagues/friends Roderick Tung and Dr. Shumpei Mori. Looking forward to this ‘next level’ resource for EP’s & our next gen/fellows in training! Part of the Amara Yad project uclahealth.org/heart/arrhythm…

Successful ablation of #WPW localized to right lateral tricuspid annulus. #ECG delta showed double transition with isoelectric sum of QRS at V2 as described in academic.oup.com/europace/artic… Mason McNeil Abbott Cardiovascular

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

Entrainment with Orthodromic Upstream Capture, 85% of TCL at suspected posterior wall circuit. #HDGrid fragmented electrograms created challenge in accurately identifying consistent PPI’s. NNE (Number Needed to Entrain) color map created in leu, right image. D Randy Jones

#WPW Localized right mid septum consistent with #ECG. Pathway potential revealed with countercurrent pacing. First lesion, first second, eliminated. D Randy Jones Brock Gambill Emily Frank Abbott Cardiovascular
