Abstract Mapping of scar‐related atrial tachycardias (AT) can be challenging even with the use of high‐density (HD) mapping catheter. AdvisorTM HD Grid is the only directional HD mapping catheter which not only identify local electrical signal but more importantly capture the direction of wave front propagation especially in low voltage zone. Accordingly, we present a case of complex scar‐related AT with the use of AdvisorTM HD Grid which showed clear fractionated signal at isthmus area as compare to the absence of signal on ablation catheter at the same area despite adequate contact force. Ablation at this area terminated the tachycardia.
