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_EPS

The value of functional substrate mapping in ventricular tachycardia ablation
heartrhythmopen.com
In the setting of structural heart disease, ventricular tachycardia (VT) is typically associated with a re-entrant mechanism. In patients with hemodynamically tolerated VTs, activation and entrainm...

Enjoying this collaboration with my beloved colleagues/friends @DrRoderickTung 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 https://t.co/2VcZ3et8d0
In development...Dedicated to making this Anatomy Atlas for Interventional EP one for the ages, at the intersection of art and science. Coming 2023. @shivkumarmd

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, @MelScheinman & @gregorymmarcus? @hrs_journal

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 @EPS_PDX

VT #StaMP guided by #DZ #ILAM with fixed RV apical pacing. Imaged: VT, ILAM, & Bipolar Voltage Maps (1.5-0.1 mv). @Ashit_EPS
Fun reproducible response to RV apical pacing, ultimately inducing this VT. Catheter strategically positioned within LV apical aneurysm. #EnSite #VT @Ashit_EPS

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. @DrGregMichaud NNE of 1’s? #EPeeps #Entrainment

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. @EPS_PDX

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
