62% of patients with recurrent symptomatic PAF have PV reconnection with PFA. Again no different to thermal!Durability of PVI Using Pulsed-Field Ablation: Results From the Multicenter EU-PORIA Registry | JACC: Clinical Electrophysiology jacc.org/doi/10.1016/j.…

The posteromedial pap muscle well defined by #PDX Initial mapping led to the PM tip. RFA shifted exit to the mid aspect then suppressed. Great mapping George Crowell #Epeeps

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

Accessory pathways related to right cardiac veins (RCV-AP), a rare type of right-sided AP, is characterized by atrial insertion distant from the annulus, and may indicate the presence of myocardial fibers along the veins beyond coronary sinus doi.org/10.1161/CIRCEP…

Maps from 3 PVIs done on a recent day look like Andy Warhol’s Campbell soup cans stacked on top of one another (hey I am on-call waiting for a patient to come down from CVICU). Like the critique against pop art, is it art? Silk screened PVIs anyone ?!🤣#EPeeps

Remote mitral valve repair. Presented with alternating mitral and roof flutters confirmed by entrainment. Anterior wall scarred so opted for anterior mitral line. Nice termination shot of the mitral flutter. Excellent mapping Lydia Trautmann George Crowell #EPeeps

PVC with abrupt V3 transition suggested L-R interleaflet triangle exit. Broad left sided early activation and poor pace mapping. Got it from below pulmonic valve w/ 98% match. Anatomy relationship always an a-ha moment. Excellent mapping Brock Gambill George Crowell #EPeeps

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

intramural LV summit PVC with V2 pattern break, broad exit. Hit it from both LV endocardium and LCC. Half normal NS RF for up to 2 min, ~700 mA current, and anterior ground location critical for success. Excellent mapping Brock Gambill #EPeeps

My PVC summer continues! 120 ms QRS PVC suspicious for fascicular origin near PM pap. 2 targeted exits and 2 morphology changes later finally got it-mapped earliest Purkinje 30 ms pre at the septal insertion of a LV false tendon. Great mapping Brock Gambill #EPeeps

Notice the possible second loop going up and around the right atrial appendage scar? ♾️ Not sure which is the dominant loop without entrainment, but from the map it looks like they both share a common isthmus? JMC Edward Gerstenfeld Jeffrey Winterfield Gregory Michaud Edward Cheng, MD, PhD

SVT during pregnancy is assoc w/ ⬆️ risk for CS & PTL in healthy women. History of SVT should be sought as early as preconception counseling, & multidisciplinary approach is warranted for both prevention & mgmt of SVT occurrence. bit.ly/3LJEEUP #JACCCEP #CardioObstetrics

AVRT via branched concealed let sided AP. Mapped and a ablated during incessant tach. First lesion at early spot with AP potential changed TCL and earliest A. Second location more lateral also with AP potential terminated in 6 sec. Great mapping at Arek Karagoezian Lydia Trautmann #EPeeps

Combo VT and PVC case. NICM-fascicular (non-Belhassen)) VT exiting from LAF, non indicible after targeting earliest exit. Also summit PVC successfully sandwiched between RL ILT and LCC. Great mapping George Crowell #EPeeps
