AF=demolition derby, flutter=NASCAR, post AF ablation AT=Formula 1. My patients are relating to this

Redo persistent AF after PVI. Veins are quiet (right image). On left, note massive voltage attenuation after vein of Marshall alcohol ablation. No RF delivered!

Redo AF and enormous CS due to persistent left SVC with figure of 8 reentry in CS. Small circuit present on proximal roof connects to a 2nd loop traveling prox to distal and then returning along floor. Terminated with ablation on proximal CS roof

Note passive activation of LA via CS to posterior wall. CS reentry has never been so clear!

Single lesion at SVC/RA junction terminated AT to sinus. I’ve noticed in a few of my old reports that the final AT in a complex case was “focal AT” from SVC/RA junction. I think this type of biatrial AT is more common than we think

Redo AF ablation with durable roof and anterior line during biatrial AT. Note the delay as the wavefront comes across the anterior LA from lateral to medial. Then early activity in SVC/RA junction as impulse uses Bachmann’s bundle to jump to RA. Down septum and up mitral isthmus

De novo clockwise mitral flutter using anterior wall scar as posterior boundary, where it was ablated successfully. How many hours have we wasted in the mitral isthmus due to lower resolution maps!!

Roof dependent AT in patient with 2 prior AF ablations. Rhythmia shows clear isthmus in posterior roof where RF terminated AT in 10 seconds
