Another case highlighting the utility of ICE during PVC ablation originating from PMs. PVCs ablated between the ALPM heads Great tissue contact, stability and real-time monitoring of lesion formation!! (pericardial effusion was pre-existing). #Epeeps with @SteliosTzeis

Epicardial VT ablation in a patient with incessant slow VT, IHD, HFrEF, CRT-D and failed endocardial ablation 2 days earlier. Epicardial "figure of eight" circuit - critical isthmus at a corridor of viable tissue within the anterior scar. Together with @DimAsvestas @K_Letsas

50yofemale with presyncope during exercise. Stress testing induced PVCs and WCT Normal ECG, echo, MRI. CA: sevLAD stenosis - PCI performed EPS/CA: VT induced by isoprenaline. SOO ablated from both RVOT and RCC. More workup? with @SteliosTzeis and @V_Michopoulos #Epeeps

#EPeeps had a very fine day with #EnSiteX #HDGrid and #OT mapping slow pathway prior to #AVNRT ablation this week. Observed nice slow junctionals with RFA at site of collision. Non-inducible post-ablation. Maps by @MeganMalladiEP Figures by @sota_ep

Nice way to ablate PVCs from the LCC-RCC commissure using ICE.@SteliosTzeis @V_Michopoulos EP Lab @MiteraHospital. #EPeeps

SAX view showed position of the catheter in this location (red arrow), posteriorly to the distal RVOT and the left pulmonary cusp, at a safe distance from the coronary arteries (yellow arrow). First, RF in RVOT was not successful. Immediate suppression just left of the commissure

Importance of rapid pacing to achieve 2:1 block during retro mapping of concealed PS AP. Looking at last 2 beats difficult to be sure where retro A starts, but with isolated V clear that it starts at red line (early) not blue (late c/w CS 7,8). Not new but worth reminder IMHO.

Periaortic #VT in a patient with non-ischemic CMP. Late potentials evident by RV pacing and ILAM is correlated to critical isthmus of tachycardia. Activation gaps in the diastolic period highlighting 3-D nature of VT-isthmus. #AblateVT,#Epeeps

First-time ablation of persistent AF in a patient with HCM using PFA guided by ICE. Strategy: PVI + posterior wall ablation. The question remains about PW ablation: "Just because we can, does it mean we should ?". @DimAsvestas @atulverma_md @Ed_Gerst @JonKalmanEP @EduardoSaad3

Results of CRAFT, our multicenter RCT in patients with flutter, comparing CTI ablation to Cryo PVI, published in @Heart_BMJ heart.bmj.com/content/early/… PVI as effective as CTI abl in reducing flutter, and better at preventing new onset AF #EPeeps @LHCHFT

Happy and proud to announce that our article on „Low-Voltage Myocardium-Guided Ablation Trial of Persistent Atrial Fibrillation“ was published in NEJM Evidence today. The first trial ever demonstrating benefit in an individualized PVI+ strategy!
