AT mapped to the lateral mitral isthmus (Rachel Willis). Distal CS signals preceded all LA signals. Notice signal change as the ablator subselects the vein of Marshall (imp. to 200+ ohms). VOM alcohol ablation terminated rhythm. Case performed by Dr. Cain at St. Helena Hospital
RIPV leak omnipolar map. Arrows constructed INDEPENDENTLY of reference catheter. Algorithm analyzes bipoles&unipoles from every right triangle of 3 adjacent electrodes on HDGrid giving us instantaneous local indication of wavefront direction. One burn isolation by @AxisDeviation
Incessant, slow idiopathic VT, looking LV Summit (MDI: 0.64). -20ms in RVOT & LCC, -40 in GCV. Mapped with #HDGrid, pacemapped perfectly 99% in LCC and GCV. Non-irrigated RF transiently suppressed at 10s. #TactiCath got it after only 2.5s. All ablation from the LCC. @AbbottCardio
