Pulsed field ablation using a variable-loop circular catheter was associated with a high rate of ICLs. More than half of the lesions were in the posterior cerebrovascular territory. https://t.co/rr1WHd9fDf

DeEP and activation mapping identified the critical isthmus in a patient with ARVC. PFA delivery terminated the VT and rendered it non-inducible.

Here we go #HRS2026 On the highly touted AVANT GAURD RCT of Boston scientific Farapulse PFA vs AAD. https://t.co/WFxMCEDHl2

The Topline results are positive. Look at that KM curve

But let's look under the hood so as not to be bamboozled

A thread coming and it's quite surprising

From chaos to cadence. Persistence met its match. 50 y old male, af terminated to SR during Ripv ablation during PFA with @AfferaEP , #Onassis Hospital

@ShariqShamimMD Thank you for the great comment! Worth clarifying — we actually tried 0.035” hydrophilic first and couldn’t cross. Escalated finally to wires build for CTOs and MC for support. And 4mm was enough to pass leads without difficulty — patency is not the goal, lead delivery is!😊

Great talk @DJ_Lakkireddy on important limitations of PFA outside of the veins. Single digit long term durability in La Fazia et al. Dual energy sources can’t come soon enough for redo ablations. There need not be discussions with current PFA iterations for VT.
