Tweetorial 1) Should we perform modification during FIRST DO? 1procedure:PVI+roof,MI,ant lines REDO due to Recurrent ATs:SR+Fib in LSPV. Bidirectional block in roof,MI Patient could’ve benefited from PVI alone.Note the low voltage in ant wall.. @evgeny_lyan @ThomasDemming #EPeeps

#EPeeps in last case we've done PVI+ roof line. The very fist burn at the roof terminated AT! After ablation the block in the roof line is proved, no tachy induction. @evgeny_lyan @ThomasDemming @KleinhansLukas @BiosenseWebster #EP_Kiel

Previous WPW case: First set of ablations in CS OS region(from ventr.side) was effective..But after 20 min conduction was resumed. Performing a CS Angio➡️Additional lesions in posterior vein abolished AP conduction @evgeny_lyan @PantlikRobert @ThomasDemming #EPeeps #EP_Bevensen

Answer to the previous case: AT1-parahisian, AT2-CristaTerminalis. Challenging mapping due to alternating of ATs. Note how perfectly P wave correlation filter discriminates between 2 morphologies!.. #Epeeps @evgeny_lyan @PantlikRobert @ThomasDemming @AbbottCardio #CardioTwitter

Tweetorial 3/3 Voltage EPI and ENDO map with @BiosenseWebster by @KleinhansLukas . Apical we see a large low voltage area. We performed an ENDO ablation around the substrate, EPI in the area of fragmented signals.
