Anterior LA pinwheel flutter, spinning around scar from prior ablations. Vectors helped to quickly define lines of block and the path of the circuit! Mapped by @C_Harrison_EP w/ Dr. Raj Shah @atrialappendage! #OT#HDGrid#Fluoroless
What’s better than one pathway…? THREE pathways! Patient presented with WPW and sustained ORT. We mapped to find a left posteroseptal AP. Following ablation, we still found 2 more pathways all 1.5cm apart! After ablating all 3 APs, we were unable to induce AVRT. #EPeeps
