Can RVOT PVCs with transition at V4 still be ablated from the left side? Despite local EGMs being much better on the right, RF resulted only in very late and brief suppression. RF from the left, opposite to the RV lesions immediately eliminated the ectopy.

Entrainment is an indispensable tool for the electrophysiologist. Colors can be misleading. Three distinct flutter circuits identified during a single procedure.

The patient with persistent atypical atrial flutter after PVI. CCW activation around mitral annulus. LIPV reconnected and the gap can be seen on its anterior aspect. Anterior mitral line slowed and terminated the flutter. Re-isolation of left TVs and CTI line afterwards.

39 yo F s/p aortic and mitral valve replacement and cryo PVI. Redo case with RSPV reconnection and re-isolation. Induced MRAT with CL of 424 ms. Confusing caudo-cranial activation on both posterior and anterior LA. Good PPI at proximal CS and LA roof.
